It's only copying the address that was returned by get string so even though conceptually is the name this program suggests, I really just want to make a copy so that maybe I can make one version of D-A-V-I-D or F-O-O all uppercase or all lowercase or I want to spell check, something.

That's certainly one way to do it, but for computers that's not necessarily the easiest way. So another way of solving it is to do something we already saw last time, which is basically, why not simply enumerate all possible examples and check them?
将一个等式代入另一个等式,这当然是一种办法,但是对电脑来说这绝对不是一件简单的事,所以解决这个问题的办法,正如我们上一次看过的,非常基本?
All right, we're-- well actually, I should say that better, we first check to see, is x 0 greater than or equal to zero, if it's not, then we come down here and we print something out, otherwise we run through a little loop to get the answer, and then we check it and we spit something out.

Is the first part. That says, I took the branch through here that eventually got to the end and said, there wasn't a solution, in which case I'mgoing to print out, there ain't no solution, otherwise I'll print out the pieces. All right, let's check it out. Ah, what did I say?
