I think it's the political implications of this missile test that are noteworthy-and that is that Iran views the talks as dead-it doesn't view the talks positively, and now it's bracing for sanctions and quite possibly for war, and this missile test is a sign that Iran takes the military option very seriously and is ready to reciprocate if it's attacked."

Let's check it out. I've written a little bit of a test script here, so if we test cell sort, and I've written this so that it's going to print out what the list is at the end of each round, OK.

And when I do this test, what I want to do, is say I'm going to pick the middle spot, and depending on the test, if I know it's in the upper half, I'm going to set my start at the mid point and the end stays the same, if it's in the front half I'm going to keep the front the same and I'm going to change the endpoint.
如果我知道目标数可能,再比中值点大的区间里,我可能就会把开始点设为中值点,而尾点不变,如果在小的那个区间里,就保持开始点不变而把尾点设为中值点,你们可以看到这儿的代码,就是这么做的,对不对?它是怎么做的?
So I'm going to go over here, and I'm going to type test search-- I can type and if you look at your handout, it's just a sequence of tests that I'm going to do OK. So initially, I'm going to set up the list to be the first million integers.
大家可以看看你们的课堂材料,那儿有一些我要做的实验,好,一开始我先去建立个,含有一百万个integer的数组,对,这有点儿简单,但是这给我提供了这样一个有序的数组。
All right? So if I called sqrt alone, that return test value is done, but in this case I bound it to test, so I can go look at test, and there it is.
执行完返回值语句,但是在这里我将把它赋值给,所以当我看test的值的时候就是返回的值。
