leetcode-231-power of two

Given an integer, write a function to determine if it is a power of two.

给定一个整数，判断是否是2的整数幂。

class Solution {
    public:
        bool isPowerOfTwo(int n) {
            while(n>1)
                {
                    if(n%2>0) return false;
                    n/=2;
                }
            return n==1;
        }
};
