i If I'm going to keep that item, item i, if I'm going to take it, I give it a 1.

But if you keep on doing boxes within boxes, I'm going to converge in on that intersection.
如果你不断缩小方格,最后就会只剩交点了
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?
I then assign thankful true, if so, but notice this little trick: -- I'm going to keep doing this while I am bang thankful -- bang exclamation point means "not," so this is shorthand, sort of clever elegant notation for "while I'm not thankful, keep doing this."
然后我给thankful赋true值,如果是这样,注意这里有个小技巧:,我将一直这样做,当我用满意时-,感叹号在这里的意思是“非“,这是一个可速记的,有几分机灵优雅的符号,用来说明:“当我不满意,保持这样做“
