PM technical question

问题：假装你在和一个陌生人说话。你会如何解释产品管理？
Pretend you’re talking to a stranger. How would you explain product management?
答：产品经理制定战略性、创造性和数据驱动的产品决策，进行用户研究和市场分析，以帮助领导产品团队创建满足客户需求的独特且有吸引力的产品，并最终帮助公司实现其业务目标。
Product Managers make strategic, creative, and data-driven product decisions, conducting user research and market analysis to help lead a product team to create unique and attractive products that meet customers’ needs and ultimately help a company meet its business goals.

除了提供对产品管理是什么的简单解释之外，还值得将其与战略问题类似地对待，并包含更多关于产品管理团队可以通过仔细引导产品从构思和产品中带来的价值的理念设计阶段到发布。
In addition to supplying a simply worded explanation of what product management is, it’s also worth treating this similar to strategy questions and including a bit more of your philosophy on the value that a product management team can bring by carefully steering products from the ideation and product design phase through launch.

问题：请解释您监控绩效和成功的方法？
Question: Please explain your approach to monitoring performance and success？

答：像这样的产品问题应该被视为一个机会，既可以展示您用于评估产品成功的过程，又可以吹嘘您过去的一些产品的成功。
Answer: Product questions like this one should be looked at as an opportunity both to show the process you use for evaluating the success of your products, as well as a chance to brag about the success of some of your past products.

讨论您如何为您从事的每个产品和项目定义相关 KPI，然后仔细监控它们是否基于以下因素进行评估：Talk about how you define relevant KPIs for each product and project you work on, then carefully monitor them whether you’re evaluating based on:

用户数The number of users
收入Revenue
漏斗Funnel*
客户终身价值Customer lifetime value
测试结果Testing results
在你的面试中，你还应该提到分析工具、用户研究策略和其他策略，以了解你的产品是如何被接收和使用的。In your interviews, you should also mention the analytics tools, user research strategies, and other tactics you employ to build an understanding of how your products are being received and used.

强调您在动态调整以提高滞后性能时对细节和适应性的关注，以及您对数据驱动决策的奉献精神。Emphasize your attention to detail and adaptability in adjusting on the fly to boost lagging performance, as well as your dedication to data-driven decision-making.

*销售漏斗是访问者到达他们成为客户的点所经历的一系列阶段。The sales funnel is the series of stages that visitors go through to reach the point at which they become customers.

通过使用某些销售漏斗指标，您将能够确定您在整个销售漏斗中失去潜在客户的位置，从而改善营销和销售工作并提高转化率。Through the use of certain sales funnel metrics, you’ll be able to identify where you’re losing prospects throughout the sales funnel so that you can improve your marketing and sales efforts and boost your conversion rate.

1. 确定漏斗各部分的总计数Identify Areas of Focus Instead of Guessing
首先要衡量的是数量——或进入销售漏斗并通过每个阶段的访客数量。以下是衡量销售漏斗量的过程：The first thing to measure is volume — or the number of visitors that are entering the sales funnel and that make their way through each stage. Here is the process for measuring the volume of your sales funnel:

测量流量
Measuring Traffic
测量流量可以让您了解您的营销工作在销售漏斗的初始阶段有多有效。有多少人正在进入销售漏斗的认知阶段？网络流量是一个非常广泛的指标，但它确实让您了解当您比较一段时间内的流量数字时，您是如何产生品牌知名度的。Measuring traffic gives you an idea of how effective your marketing efforts are at the initial stages of the sales funnel. How many people are entering the awareness stage of the sales funnel? Web traffic is a pretty broad metric to follow, but it does give you an idea of how you’re doing generating brand awareness when you compare traffic numbers over time.

测量返回流量
Measuring Return Traffic

并非每位访问者都会在首次​​访问您的网站时进入销售漏斗的下一阶段。如果您在意识阶段没有很好地告知他们他们的问题或需求，他们可能会离开去寻找另一个信息来源。测量返回流量可以让您了解您在意识阶段的营销工作的有效性。这意味着离开的访问者已经回来做进一步的研究，无论他们是否仍处于意识阶段，或者他们已经在销售漏斗中移动得更远。高流量数字但低返回流量数字通常表明，虽然您在吸引潜在客户到您的网站方面做得很好，但在保持他们的参与度方面做得很差。
Not every visitor will advance to the next stage of the sales funnel on their first visit to your website. If you don’t do a good job informing them about their problem or need during the awareness stage, they may leave to find another source for their information. Measuring return traffic gives you an idea of how effective your marketing efforts during the awareness stage were. It means that the visitor who left has come back to do further research, whether they’re still in the awareness stage or they’ve moved further down the sales funnel. High traffic numbers but low return traffic numbers often indicate that while you’re doing a good job attracting potential leads to your website, you’re doing a poor job keeping them engaged.

产生的测量线索Measuring Leads Generated
仅仅因为有人访问您的网站并不会自动使他们成为潜在客户。只有表现出一定的兴趣，潜在客户才能成为合格的潜在客户。在衡量您生成的潜在客户数量时，有两种类型的潜在客户需要衡量：MQL（营销合格潜在客户）和 SQL（销售合格潜在客户）。潜在客户使用潜在客户评分软件指定为 MQL 或 SQL，该软件根据他们提供的信息或他们采取的行动为每个潜在客户分配分数。Just because someone visits your website doesn’t automatically make them a lead. It’s only by showing a certain amount of interest that prospects become qualified leads. When measuring the number of leads that you’ve generated, there are two types of leads to measure: MQL (marketing qualified leads) and SQL (sales qualified leads). Leads are designated as MQL or SQL using a lead scoring software that assigns points to every prospect based on the information they’ve provided or the actions that they’ve taken.

营销合格的潜在客户Marketing Qualified Leads
衡量您随时间生成的 MQL 数量有助于您确定销售漏斗中间（兴趣阶段）的有效性。MQL 是已被确定为可能成为客户的潜在客户。低数量的 MQL 意味着您没有很好地将线索从意识阶段引导到兴趣阶段。Measuring the number of MQLs you’ve generated over time helps you identify the effectiveness of the middle of your sales funnel (the interest stage). An MQL is a lead that has been identified as someone who is likely to become a customer. A low number of MQLs means that you’re not doing a good job guiding leads from the awareness stage to the interest stage

销售合格的潜在客户Sales Qualified Leads
与 MQL 不同，SQL 是已被确定为更有可能很快购买的线索。在理想情况下，SQL 的数量应该反映您生成的 MQL 的数量。这表明您已经成功地从销售漏斗到决策阶段培养了您的 SQL，并且它们已准备好被您的销售团队参与。As opposed to MQLs, SQLs are leads that have been identified as being more likely to make a purchase soon. In a perfect world, the number of SQLs should mirror the number of MQLs you’ve generated. This indicates that you’ve successfully nurtured your SQLs through the sales funnel down to the decision-making stage and they are ready to be engaged by your sales team.

衡量销售机会Measuring Sales Opportunities
不要将您的 SQL 误认为是销售机会。SQL 仍然只是你认为的潜在客户——通过他们的行动和个人信息——准备好被你的销售团队聘用。它们还不代表销售机会。SQL 可能仍需要由您的销售团队培养，然后才能成为实际的销售机会。只有当您的销售团队与他们联系并确定他们提供机会时，他们才会成为销售机会。在您联系他们之前，他们仍然只是 SQL。通过衡量您的销售机会，您将能够确定您的团队与识别为 SQL 的潜在客户互动的效率。Don’t mistake your SQLs as sales opportunities. SQLs are still just leads who you think – through their actions and personal information – are ready to be engaged by your sales team. They don’t yet represent sales opportunities. SQLs may still need to be nurtured by your sales team before they become an actual sales opportunity. They only become sales opportunities when your sales team reaches out to them and determines that they present an opportunity. Before you reach out to them, they are still only SQLs. By measuring your sales opportunities, you’ll be able to identify how effectively your team has been able to engage with leads identified as SQLs.


衡量已完成的赢得交易Measuring Closed Won Deals
达成交易的能力表明您的销售策略有多有效。如果您有大量的 SQL 和销售机会，但转化次数很少，这意味着您的销售漏斗末端存在问题。当您的已完成交易的数量尽可能接近您的销售机会时，这是理想的选择。The ability to close deals indicates how effective your sales strategy is. If you have a high number of SQLs and sales opportunities but a low number of conversions, it means that there’s an issue at the end of your sales funnel. It is ideal when your closed deals are as close in number as possible to your sales opportunities.

问题： 解释良好用户界面的关键？Question: Explain the key to a good user interface.
答：简单性和功能性对于良好的用户界面都是至关重要的。它们应该是直观的使用和导航，具有一致的外观和感觉。Answer: Simplicity and functionality are both crucial to a good user interface. They should be intuitive to use and navigate, with a consistent look and feel.


用一个实际例子回答
This question type could be a good opportunity for you to bring in a real-life example or two.


尝试展示您认为具有特别有吸引力和功能界面的产品（您甚至可以考虑在这里展示您自己的作品）和另一个您认为不起作用的产品（以及改进它的一两个想法）。
Try showcase a product that you think has a particularly attractive and functional interface (you could even consider showing your own work here) and another that you think doesn’t work (along with an idea or two to improve it)

问题：你有什么使你与其他产品经理不同的技术技能吗？
Question: Do you have any technical skills that set you apart from other Product Managers?

答：不同的公司对他们的产品经理的技术知识水平有不同的要求——例如，人们常说谷歌更喜欢像软件工程师一样学会编码的产品经理。
在面试之前，记下你认为自己已经掌握的所有编程语言，以及其他技术优势领域。此外，请记住，您的面试官可能不是来自技术背景，因此请准备好提供外行的翻译，了解这些技能如何为产品经理的工作角色带来价值。
Answer: Different companies require different levels of technical know-how from their PMs – it’s often said that Google, for instance, prefers Product Managers who have learned to code like a Software Engineer.
Before your interview, jot down all the programming languages you feel you’ve mastered, along with other areas of technical strength. Also, keep in mind that your interviewer might not come from a technical background, so be prepared to provide a layman’s translation for how those skills could bring value to a Product Manager job role.



Additional Technical Product Manager Interview Questions
-- How do you define market opportunity in a business plan?
这是您的市场和销售的预计潜在规模。您的商业计划的市场机会部分是您提供经过充分研究的估计，估计有多少消费者或企业属于您的目标市场，以及您可以从该市场获得多少潜在销售额。It’s the projected potential size of your market and sales. The market opportunity section of your business plan is where you provide a well-researched estimate of how many consumers or businesses belong to your target market, as well as how much potential sales you could make from that market.

它基本上回答了这个问题，“有多少人想要你提供的产品或服务？”It basically answers the question, “How many people want the product or service you are offering?”

根据我们的商业计划专家 Cheree Warrick 的说法，商业目标包含在此部分中。“例如，我可能会说，“有 10,450 人居住在我餐厅方圆 1 英里的范围内。我的每日目标是以每人 15 美元的平均价格点（或订单量）每天售出 330 份餐食。” 切丽解释道。According to our Business Plans Expert Cheree Warrick, the business goals are included in this section., “For example, I might say, “There are 10,450 people that live within a 1-mile radius of my restaurant. My daily goal is to sell 330 meals per day at an average price point (or order size) of $15 per person.” Cheree explains.

市场机会：如何识别和书写？Market Opportunity: How to Identify and Write?
以下是有关如何识别市场机会并将其写入业务计划的步骤。The following are steps on how to identify and write your market opportunity on your business plan.

第1步：你的目标客户是谁？Step 1: Who is your Target Customer?
您的第一步是定义您的销售对象。您的目标市场（也称为您的甜蜜点）与您认为最有可能购买您的特定产品或服务的理想客户有关。尽管您想迎合所有人，但您的业务不可能对所有人都适用。无论您考虑产品或服务的吸引力有多大，并不是每个人都会对它感兴趣。Your first step is to define who you’re selling to. Your target market – also known as your sweet spot – pertains to ideal customers you believe will most likely buy your particular product or service. As much as you would want to cater to everybody, your business can’t be all things to all people. No matter how broad you consider the appeal of your product or service, not everyone will be interested in it.

以下 3 个因素可以帮助您确定理想的客户：Here are 3 factors that can help you identify your ideal customer:
1) 人口统计数据（例如年龄、性别、收入、婚姻状况、职业/行业和教育水平等）Demographics (ex. Age, Gender, Income, Marital Status, Occupation/Industry, and Educational Level, etc.)
2) 位置 Location
3) 心理学（兴趣、态度/意见、爱好、常规活动和行为）Psychographics (Interest, Attitudes/Opinions, Hobbies, Regular Activities, and Behaviors)

您还可以使用 Facebook Audience Insights 和 Google Trends 等市场工具。You can also use Market Tools such as Facebook Audience Insights and Google Trends.

第 2 步：确定有利可图的市场并收集数据以支持它 Step 2: Identify a Profitable Market and Gather Data to Support It

下一步是根据可信和可靠的统计数据、事实和研究为您的企业确定一个有利可图的市场。
这里有3件事要弄清楚：The next step is to identify a profitable market for your business based on trusted and reliable statistics, facts, and studies.
Here are 3 things to figure out:
1) 市场规模：
有多少潜在客户可用？了解目标客户的特征很重要的原因是帮助您准确估计您的市场规模。
Market Size:
How many potential customers are available? The reason why it's important to know the characteristics of your target customer very well is to aid you in having an accurate estimate of your market size.
2) 盈利能力：
您的潜在客户是否愿意并且有能力购买您的产品和服务？
Profitability:
Are your potential customers willing and able to spend on your products and services?
3) 潜在增长：
是否有迹象或研究表明市场规模会增长、保持相对静止或下降？
Potential Growth:
Are there signs or studies that the size of the market will grow, stay relatively static, or decrease?


--2. To build your product roadmap, what inputs do you use?

product-related
1)market needs
2)business goals - profitability, growth - deliver the outcomes
3)key features - product hooks - aha moment, engage your customer

quantity up: add ideas - group the ideas based on 123

--3. What is a product you can’t live without? How would you improve it?
举例问题
for me -- google map in the US
transportation + restaurant review website + location markets
add augmentation video services +  continuously improve accuracy + security helps + directly sell tickets

--4. Please explain how you managed the roadmap for a product in the past.
如果没有成熟的产品经验，比如找intern的话，可以基于自己上课学习到的东西说一个你自己的SOP：
Visualize it all on a timeline+releases+features
Building a product roadmap starts with strategy — you must establish the product goals and initiatives that your efforts will support. Once those are defined, you can decide which releases and features are best aligned with your strategy and then visualize it all on a timeline.
构建产品路线图从战略开始——您必须建立您的努力将支持的产品目标和计划。一旦定义了这些，您就可以决定哪些版本和功能最符合您的策略，然后在时间线上将其全部可视化。
Participants
A few considerations will shape your road mapping process. One is your audience — what you show on your roadmap depends on your intended viewers. In the table above, you saw how different types of roadmaps help to highlight different elements. As you build and customize your product roadmap, you can make additional decisions about which details to include (and which to leave out) so that the information portrayed is relevant to whoever is viewing it.
一些考虑因素将塑造您的路线图流程。一个是你的观众——你在路线图上展示的内容取决于你的目标观众。在上表中，您看到了不同类型的路线图如何帮助突出显示不同的元素。在您构建和自定义产品路线图时，您可以就要包括哪些细节（以及要省略哪些细节）做出额外的决定，
Track and visualize following the strategy

For example, the leadership team will want to understand the strategic importance of what you will deliver, conveyed through roll-up relationships between major releases and associated goals and initiatives. Your product marketing team, on the other hand, will be more concerned with the details and dependencies — so they can track and visualize moving pieces leading up to a product launch and coordinate all go-to-market plans accordingly. 例如，领导团队将希望了解您将交付的内容的战略重要性，通过主要版本与相关目标和计划之间的汇总关系来传达。另一方面，您的产品营销团队将更加关注细节和依赖关系——因此他们可以跟踪和可视化导致产品发布的移动部件，并相应地协调所有上市计划。

You might share a version of your roadmap with customers too. Customers will want to see what is upcoming — especially any critical functionality they need. On a customer-facing roadmap, you might choose to show a broader release time frame instead of an exact date so that you have the flexibility to shift if necessary.您也可以与客户分享您的路线图版本。客户将希望了解即将推出的功能——尤其是他们需要的任何关键功能。在面向客户的路线图上，您可能会选择显示更广泛的发布时间框架而不是确切的日期，以便您可以在必要时灵活调整。
Follow the current value
Your product roadmap will also reflect the development methodology that your organization follows. For example, an agile team will create a product roadmap that is incremental and flexible to accommodate changes in customer needs and the market. But product roadmaps for organizations following a traditional waterfall approach will be more fixed — conveying a long-term commitment to building specific features within a given time frame. 您的产品路线图还将反映您的组织遵循的开发方法。例如，敏捷团队将创建一个增量和灵活的产品路线图，以适应客户需求和市场的变化。但是，采用传统瀑布方法的组织的产品路线图将更加固定——传达出在给定时间范围内构建特定功能的长期承诺。

Components of a product roadmap 产品路线图的组成部分：
Goals, releases, epics, features, timeline,
The details and context may vary, but all product roadmaps should include a few key elements. Here is a quick overview of the main components you need: 细节和背景可能会有所不同，但所有产品路线图都应包含一些关键要素。以下是您需要的主要组件的快速概览：
Goals: Measurable, time-bound objectives with clearly defined success metrics. Goals represent the critical accomplishments needed to deliver your product.
目标：具有明确定义的成功指标的可衡量的、有时限的目标。目标代表交付产品所需的关键成就。
Initiatives: High-level themes of work describing how your efforts will contribute to your goals. On a roadmap, initiatives show how specific releases and features relate to your strategy.
倡议：描述您的努力将如何为您的目标做出贡献的高级工作主题。在路线图上，计划会显示特定版本和功能与您的策略的关系。
Releases: A launch of new product functionality represented on a timeline. Releases often contain multiple features that get delivered at the same time.
发布：在时间线上表示的新产品功能的发布。版本通常包含同时交付的多个功能。
Epics: Larger bodies of work (like categories) that typically span multiple releases. Epics break down into smaller features that are delivered incrementally.
史诗：通常跨越多个版本的大型工作（如类别）。史诗分解成增量交付的较小功能。
Features: A specific piece of new or improved functionality that results in value to users. Features can be related to capabilities, components, appearance, and performance.特性：为用户带来价值的特定新功能或改进功能。特性可以与功能、组件、外观和性能相关。
Timeline: A visualization of when product releases will occur over time. The time scale can range anywhere from days to quarters or years depending on the amount of work and level of detail involved in a particular release.
时间线：随着时间的推移，产品发布时间的可视化。时间范围可以从几天到几个季度或几年不等，具体取决于特定版本中涉及的工作量和详细程度。

How to create a product roadmap
With these components and considerations in mind, here are the five main steps to building a product roadmap:
1. Define your product strategy 定义你的产品策略
As mentioned above, setting strategic product goals and initiatives is an important first step in building a roadmap. Strategy is the "why" behind your product — it explains how your efforts will support the overall business. You will also need a strong product vision — capturing who your customers are, what they need, and how you will go to market with your offering. Together, the elements of your product strategy will inform everything that goes on your roadmap. 如上所述，设定战略产品目标和计划是构建路线图的重要第一步。战略是产品背后的“原因”——它解释了你的努力将如何支持整个业务。您还需要一个强大的产品愿景——了解您的客户是谁、他们需要什么，以及您将如何将您的产品推向市场。一起，您的产品战略元素将告知您路线图上的所有内容
2. Review and manage ideas审查和管理想法
Most product teams have a co nstant influx of product ideas from customers and customer-facing internal teams. When these ideas are organized and prioritized, they are valuable input for deciding what to put on your roadmap. For an objective method of idea evaluation, try scoring ideas based on metrics that reflect your strategy. 大多数产品团队都有来自客户和面向客户的内部团队的不断涌入的产品创意。当这些想法被组织和优先考虑时，它们对于决定在您的路线图上放置什么是有价值的输入。对于想法评估的客观方法，请尝试根据反映您的策略的指标对想法进行评分。
3. Define features and requirements 定义功能和要求
This is when your product roadmap starts to take shape. With your goals, initiatives, and prioritized ideas to guide you, identify the specific product features that you want to deliver. Use a template or tool to put your features into words, add the necessary details in the requirements, and group related ones into epics (if needed). Anything valuable that does not fit on the first iteration of your product roadmap can be saved for later in your product backlog.
这是您的产品路线图开始形成的时候。根据您的目标、计划和优先考虑的想法来指导您，确定您想要提供的特定产品功能。使用模板或工具将您的功能转化为文字，在需求中添加必要的细节，并将相关的细节分组（如果需要）。任何不适合您的产品路线图第一次迭代的有价值的东西都可以保存到您的产品待办列表中。
在这个阶段，您还可以将您的功能转换为用户故事，以从客户的角度描述收益。用户故事为您的工程团队提供实施最佳解决方案所需的环境。
At this stage, you can also translate your features into user stories to describe the benefit from the customer's perspective. User stories give your engineering team the context they need to implement the best solutions.
4. Organize into releases 组织成发布
Up to this point, you have focused on defining the "why" and the "what" for your product roadmap — next, you will think about the "when." Once your features are prioritized and sorted, you can plot out your delivery timeline with releases. Releases are often organized by product launch but some teams prefer to arrange their roadmaps based on development capacity.
到目前为止，您已经专注于为您的产品路线图定义“为什么”和“什么”——接下来，您将考虑“何时”。一旦你的功能被优先排序和排序，你就可以用发布来绘制你的交付时间表。发布通常是按产品发布来组织的，但一些团队更喜欢根据开发能力来安排他们的路线图。
5. Choose roadmap views 选择路线图视图
To get your product roadmap up and running, the final step is to visualize everything you have defined up to this point. Try roadmap templates or a roadmapping software tool to experiment with different roadmap views. Consider the following questions to help you decide what to include: 为了让您的产品路线图启动并运行，最后一步是可视化您到目前为止定义的所有内容。尝试使用路线图模板或路线图软件工具来试验不同的路线图视图。考虑以下问题，以帮助您决定包含哪些内容：
Who needs to see this product roadmap? 谁需要查看此产品路线图？
What is the most important information I want to convey? 我想传达的最重要的信息是什么？
Does my audience care more about the big picture or details? 我的观众更关心大局还是细节？
Does my audience need to know the general timing or exact dates? 我的听众是否需要知道一般时间或确切日期？

总而言之就是要建立一个对观众有用的工具#帮助他们管理任务#启发创新#mece！～

Here are five common types of product roadmaps and what makes each of them useful:
Epics roadmap
史诗路线图 - 计划和组织开展工作
Helps you plan and organize upcoming work by grouping related features together. An epics roadmap is useful for visualizing work delivered across multiple releases, communicating key focus areas, and making prioritization decisions.通过将相关功能组合在一起，帮助您计划和组织即将开展的工作。史诗路线图对于可视化跨多个版本交付的工作、传达关键重点领域以及制定优先级决策非常有用。
Features roadmap
功能路线图 - 交付时间线
Shows the timeline for when new features will be delivered. Features roadmaps are perfect for communicating the details of what is coming and when to customers and other teams. 显示交付新功能的时间线。功能路线图非常适合向客户和其他团队传达即将推出的内容和时间的详细信息。
Portfolio roadmap
投资组合路线图 - 广泛多个产品团队协同
Shows planned releases across multiple products in a single view. Portfolio roadmaps are useful for providing a strategic overview of your plan to leadership and a broad view of how multiple product teams work together.在单个视图中显示跨多个产品的计划发布。产品组合路线图有助于为您的领导计划提供战略性概述，并广泛了解多个产品团队如何协同工作。
Release roadmap
发布路线图 - 跨职能部门协调发布活动
Communicates the activities that must happen before you can bring releases to market — what needs to be done when and who is responsible for delivery. Release roadmaps are helpful for coordinating release activities with other cross-functional teams, such as marketing, sales, and customer support.传达在将版本推向市场之前必须发生的活动——需要在何时完成以及由谁负责交付。发布路线图有助于与其他跨职能团队（例如营销、销售和客户支持）协调发布活动。
Strategy roadmap
战略路线图 - 跨职能团队总体业务战略
Displays the high-level efforts that you plan to invest in to achieve your product goals. A strategy roadmap is great for presenting progress on initiatives to leadership and keeping cross-functional teams aligned on overarching business strategy.显示您为实现产品目标而计划投入的高水平工作。战略路线图非常适合向领导层展示举措的进展，并使跨职能团队在总体业务战略上保持一致。

-- Define machine learning.
What is machine learning simple definition?
Machine learning is a subfield of artificial intelligence, which is broadly defined as the capability of a machine to imitate intelligent human behavior. Artificial intelligence systems are used to perform complex tasks in a way that is similar to how humans solve problems.
机器学习是人工智能的一个子领域，它被广义地定义为机器模仿人类智能行为的能力。人工智能系统用于以类似于人类解决问题的方式执行复杂任务。
Cognitive technology

-- Define recursion.https://www.cs.utah.edu/~germain/PPS/Topics/recursion.html
Recursion means "defining a problem in terms of itself". This can be a very powerful tool in writing algorithms. Recursion comes directly from Mathematics, where there are many examples of expressions written in terms of themselves. For example, the Fibonacci sequence is defined as: F(i) = F(i-1) + F(i-2)
递归意味着“根据自身定义问题”。这可能是编写算法的一个非常强大的工具。递归直接来自数学，其中有许多用它们自己编写的表达式示例。例如，斐波那契数列定义为：F(i) = F(i-1) + F(i-2)

Recursion is the process of defining a problem (or the solution to a problem) in terms of (a simpler version of) itself.
For example, we can define the operation "find your way home" as:
If you are at home, stop moving.
Take one step toward home.
"find your way home"
Here the solution to finding your way home is two steps (three steps). First, we don't go home if we are already home. Secondly, we do a very simple action that makes our situation simpler to solve. Finally, we redo the entire algorithm.
The above example is called tail recursion. This is where the very last statement is calling the recursive algorithm. Tail recursion can directly be translated into loops.



The above example is called tail recursion. This is where the very last statement is calling the recursive algorithm. Tail recursion can directly be translated into loops.


Parts of a Recursive Algorithm
All recursive algorithms must have the following:
Base Case (i.e., when to stop)
Work toward Base Case
Recursive Call (i.e., call ourselves)
递归算法的一部分
所有递归算法必须具有以下内容：
基本情况（即何时停止）
朝着基本案例努力
递归调用（即调用我们自己）
The "work toward base case" is where we make the problem simpler (e.g., divide list into two parts, each smaller than the original). The recursive call is where we use the same algorithm to solve a simpler version of the problem. The base case is the solution to the "simplest" possible problem (For example, the base case in the problem 'find the largest number in a list would be if the list had only one number... and by definition, if there is only one number, it is the largest).
“针对基本情况的工作”是我们使问题更简单的地方（例如，将列表分成两部分，每部分都小于原始部分）。递归调用是我们使用相同算法来解决问题的更简单版本的地方。基本情况是“最简单”可能问题的解决方案（例如，问题“查找列表中的最大数”中的基本情况是如果列表只有一个数字......并且根据定义，如果有只有一个数字，它是最大的）。
