感谢楼主！祝拿offer!

谢啦~，大家都搞定~

有同学说看不到图，照着敲了一遍：

For input your receive a string that represents all text in a file.
Lines in the string are separated by '\n' and words in the lines are separated by spaces.

Write a function that parses the file and returns a string containing all the words in a file in alphabetical order and the line numbers containing the words.
The index built should be case insensitive and the results should be all lower case.

Consider this example input:

1. My name is Simon
   
2. my favorite color is blue
   
3. Why is the sky blue

复制代码

The function should return:

1. blue 2,3
   
2. color 2
   
3. favorite 2
   
4. is 1,2,3
   
5. my 1,2
   
6. name 1
   
7. simon 1
   
8. sky 3
   
9. the 3
   
10. why 3

复制代码

谢谢楼主，这题的 function signature 是啥呀？

印象中应该是 string f(string) 吧

请问楼主为何你的是hackrank上的OA?

楼主，hackrank上面开摄像头吗？屏幕录像吗？

不用开摄像头，屏幕录像不知道，应该没有吧。
