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:
primes = [1]*1000001
primes[0]=primes[1]=0
for i in range(2,int(1000001**0.5)):
	if primes[i]:
		for j in range(i**2,1000001,i):
			primes[j]=0

import math
n = int(input())
x = list(map(int,input().split()))
for item in x:
	root = math.sqrt(item)
	if item==1:
		print("NO")
	elif item==4:
		print("YES")
	elif item%2==0:
		print("NO")	
	elif int(root+0.5)**2==item and (primes[int(root)]):
		print("YES")
	else:
		print("NO")
