Now I seem to be violating my own mantra here by just calling this variable A, but this is reasonable, I much as with four loops when you just call an incrementing variable I, because you just need an index, well, same here.

Again I should have said first, index 0, the first one. I can similarly go in and say I'd like all the things between index 2 and index 4. And again, remember what a b c that does. Index 2 says start a 0. 1, 2. So a, b, c.
我还是要说一遍，索引为0的元素，是第一个元素，我可以要求返回索引,2和4之前的所有元素，请记住2,是从0开始的,那么0，1，2对应的是。

I get to the end of the loop, and I actually do a little bit of wasted motion there. And the little bit of wasted motion is, I take the value at i, store it away temporarily, take the value where min index is pointing to, put it back in there, and then swap it around.
我走到了循环的末尾，事实上我做了多余的动作了,有点多余的是我把i的值，临时保存起来了，看看MinIndex指向的值，放回到哪里，然后再交换。

To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.
取得列表中的任何一个值,简单说来，想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4，加到start上,然后定位到内存单元，并取出值就是固定的时间了,好的，如果元素以固定大小存储。
