Day-08-Power of Two.cpp

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

Example 1:

Input: 1
Output: true
Explanation: 20 = 1
Example 2:

Input: 16
Output: true
Explanation: 24 = 16
Example 3:

Input: 218
Output: false




class Solution {
public:
    bool isPowerOfTwo(int n) {
         if(abs(floor(log2(n))-ceil(log2(n)))==0) return true;
         else return false;
    }
};
