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 TPrimes(n,arr):
    l = [1]*1000001
    l[0] = 0
    l[1] = 0
    limit = int(1000001**(1/2))
    for i in range(2,limit):
        if l[i] == 1:
            k = i
            while k+i <= 1000000:
                k += i
                l[k] = 0
    for i in arr:
        ok = int(i)**(1/2)
        if ok == int(ok):
            if l[int(ok)] == 1:
                print("YES")
            else:print("NO")
        else:
            print("NO")
n = int(input())
arr = list(map(int,input().split()))
