Implement Pow (x, n).This problem let us ask X of the N-square, if we simply use a for loop to X times their own n time, it would be too easy to think on the Leetcode, a word describing the pattern Tucson broken AH. OJ cannot pass because of timeout, so we need to optimize our algorithm so that it can work out the results more efficiently. We can use the recursive return binary calculation, each time the n is reduced by half, so that N will eventually
