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:
def istprime(n):
	if(n==1):
		return "NO"
	else:
		x=n**0.5
		if(int(x)!=x):
			return "NO"
		else:
			z=int(x)
			if(z%2==0):
				if(z==2):
					return "YES"
				else:
					return "NO"
			else:
				for i in range(3,int(z**0.5)+1,2):
					if(z%i==0):
						return "NO"
				return "YES"

t=int(input())
L=list(map(int,input().split()))
for i in range(0,t):
	print(istprime(L[i]))
