/* write a c++ program power of 2.<gfg>
Given a positive integer N, check if N is a power of 2.
Input:
The first line contains 'T' denoting the number of test cases. Then follows description of test cases.
Each test case contains a single positive integer N.
Output:
Print "YES" if it is a power of 2 else "NO". (Without the double quotes)
Constraints:
1<=T<=100
0<=N<=10^18
Example:
Input :
2
1
98
Output :
YES
?NO
Explanation:  (2^0 == 1)
