Problem: A Power Number is a positive number that can be expressed as x^x, i.e. x raise to the power of x, where x is any positive number. You will be given an integer array A and you need to print if the elements of array A are Power Numbers or not.

Input: First line contains N, a positive integer.

Next line contain N space-separated integers.

Output: For every integer, print 'Yes' if its a power number, else print 'No'. These outputs must be separated by space.

Constraints: 1 ≤ N ≤ 100

1 ≤ A[i] ≤ 10^16

Sample Input: 3

1 3 4

Sample Output: 

Yes No Yes
