唔布跪经

两轮店面，第一轮没写对，思路错了（后来发现是裂口原题），感谢第一轮中国大哥高抬贵手，又安排了第二轮。但第二轮很扯，不知道是不是听说我写过前端，出了个从来没见过的题，直接交了个白卷，还请知道思路的题友指点一二。

第一轮题目如下：

// This is the text editor interface.
// Anything you type or change here will be seen by the other person in real time.
//call stack profiling,
/*
logs
enter func1 ts1
enter func2 ts2
exit func2 ts3
exit func1 ts4

question, what is exclusive time used by a function (e.g fnc1)
func1 ts4 - ts1 - ( ts3 - ts2)

input list of logs, records enter/exits time of funcitons
output will be exclustive time used by a "given&qu

n(msg) {    console.log(`got "${msg}", happyBirthdayGreet should have been called once and was called ${greetingCalled} time(s)`)    bd('Anne', 31, function(msg) {      console.log(`got "${msg}", happyBirthdayGreet should have been called twice and was called ${greetingCalled} time(s)`)    })  })})%希望对准备面试的有所帮助！

第二题不知为啥格式有问题。

// This is the text editor interface.
// Anything you type or change here will be seen by the other person in real time.

// memoization: (x, y) => x + y

// fs.readFile('foo.txt', function(text) {})
// var memoizedReadFile = asyncMemoize(fs.readFile)
// memoizedReadFile('foo.txt', function(text) {}) // hits disk, caches result, and calls callback
// memoizedReadFile('foo.txt', function(text) {}) // only returns cache
// memoizedReadFile('bar.txt', function(text) {}) // hits disk




/**
* fn: asyncrounous function where the last argument is a callback
* (a function taking one argument that is a result)
*
* Given a function, return another function that when it is called
* with the same parameters (sans callback) of a previous invocation,
* does not call the original `fn` but "immediately" callbacks with
* with the cached result.
*/
function asyncMemoize(fn) {

}

var keyObject={
    String funName;
    ArrayList<Object> params;
}

// test cases
var greetingCalled = 0
var happyBirthdayGreet = function(person, age, cb) {
  greetingCalled++
  setTimeout(() => cb(`Happy ${age}${{1:'st', 2:'nd'}[age % 10] || 'th'} Birthday ${person}!`), 800)
}

var bd = asyncMemoize(happyBirthdayGreet)

bd('Bob', 24, function(msg) {
  console.log(`got "${msg}", happyBirthdayGreet should have been called once and was called ${greetingCalled} time(s)`)
  bd('Bob', 24, function(msg) {
    console.log(`got "${msg}", happyBirthdayGreet should have been called once and was called ${greetingCalled} time(s)`)
    bd('Anne', 31, function(msg) {
      console.log(`got "${msg}", happyBirthdayGreet should have been called twice and was called ${greetingCalled} time(s)`)
    })
  })
})%
