xxx: Some programmers use the fountain method to de-order the code. To do this, you need to put a toy duck on the desk (or present it) and explain in detail line by line what the program should do. By resorting to this method, the programmer often encounters a demanding error, which he did not notice when viewing the code in the development environment.

WOW: Yes, I almost do that.

I only have a timid instead of a whirlwind.
