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:
import math

pr = [1]*1000010

def __init():
    pr[0],pr[1]=0,0
    for i in range(2,int(math.sqrt(1000010))+1):
        if pr[i]:
            for j in range(2*i,1000010,i):
                pr[j]=0;

def isTPrime(n):
    root = int(math.sqrt(n))
    if root**2 == n:
        return pr[root]
    return 0

n = int(input())
arr = list(map(int,input().split()))

__init()
for i in range(0,n):
    stat = isTPrime(arr[i])
    if stat:
        print('YES')
    else:
        print('NO')
