Problem: We know that prime numbers are positive integers that have exactly two distinct positive divisors. Similarly, we'll call a positive integer t Т-prime, if t has exactly three distinct positive divisors.

You are given an array of n positive integers. For each of them determine whether it is Т-prime or not.

Input

The first line contains a single positive integer, n (1 ≤ n ≤ 105), showing how many numbers are in the array. The next line contains n space-separated integers xi (1 ≤ xi ≤ 1012).

Please, do not use the %lld specifier to read or write 64-bit integers in С++. It is advised to use the cin, cout streams or the %I64d specifier.

Output

Print n lines: the i-th line should contain "YES" (without the quotes), if number xi is Т-prime, and "NO" (without the quotes), if it isn't.

Examples

Input

3
4 5 6


Output

YES
NO
NO

Note

The given test has three numbers. The first number 4 has exactly three divisors — 1, 2 and 4, thus the answer for this number is "YES". The second number 5 has two divisors (1 and 5), and the third number 6 has four divisors (1, 2, 3, 6), hence the answer for them is "NO".

Solution (in PYTHON3):

Solution:
from sys import stdin
import math
a=int(stdin.readline())
A=stdin.readline().split()
for k in range(0,a):

   Q=0
   if int(A[k])==1 or int(A[k])==3:
       print('NO')
       continue

   if math.floor(math.sqrt(int(A[k])))==math.sqrt(int(A[k])):
       B=int(math.sqrt(int(A[k])))
       for k in range(2,math.floor(math.sqrt(B))+1):
           if B%k==0:
               print('NO')
               Q=1
               break
   else:
       print('NO')
       Q=1

   if Q==0:
       print('YES')
