我们之间的这几番交流表明，有时候必须反复多次才能彻底了解问题的实质。

This exchange shows that sometimes you have to iterate to get to the bottom of an issue.

死记硬背建立在这个理论之上——如果你反复的看一个信息很多次，它就会魔法般的储存在你的大脑里。

Rote memorization is based on the theory that if you look at information enough times it will magically be stored inside your head.

还要记住的是，在循环中，每次反复都是在浪费时间，因此不要多次使用相同的循环，而是要尽量在一个循环中执行所有的操作。

Remember also that each iteration through the loop wastes time, so rather than working through the same loop a number of times, try to perform all the actions in one pass through the loop.
