I've got a list, walk you through it an element at a time, do I look at each element of the list more than once?

你一次只能得到他的一个元素,我是不是把数组里面的每个元素，都过了大于等于一次？,你不这样认为么？大家有什么建议？

That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.

现在我的过程就是,通过一个个访问这个集合中,的元素的方式，来遍历这个集合,为了达到这个目的，我们有一个特定的结构，成为FOR循环。
