Solution (in PYTHON):

Solution:
import math
def is_prime(n):
    if n == 2:
        return True
    if n % 2 == 0:
        return False
    max = n**0.5+1
    i = 3
    while i <= max:
        if n % i == 0:
            return False
        i+=2
    return True

	
t = int(raw_input())
raw_input()
while t>0:
	n=int(raw_input())
	if is_prime(n):
		print "YES"
	else:
		print "NO"
	t=t-1
