Leetcode 231: Power of Two

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

 

public class Solution {
    public bool IsPowerOfTwo(int n) {
        if (n <= 0) return false;
        if (n <= 2) return true;
        
        while (n > 2)
        {
            if (n % 2 != 0) return false;
            n = n / 2;
        }
        
        return true;
    }
}
