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:
N = 1000000
primeFlagList = [True]*(N)
primeFlagList[0] = False
primeFlagList[1] = False

numSet = set()

for i in range(2,N):
	if primeFlagList[i] is True:
		primeFlagList[i*2::i] = [False]*len(primeFlagList[i*2::i])
		# for j in range(i*2,N,i):
			# primeFlagList[j] = False
		numSet.add(i*i)	


nStr = input()
# n = int(nStr)
numList=list(map(int,input().split()))
for number in numList:
	if number in numSet:
		print('YES')
	else:
		print('NO')
