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 CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
bool ar[1000005];
vector<long long> v;
void seive() {
  ar[0] = 1;
  ar[1] = 1;
  for (long long i = 2; (i * i) < 1000005; i++) {
    if (ar[i] == 0) {
      for (long long j = i * 2; j < 1000005; j += i) ar[j] = 1;
    }
  }
}
int main() {
  long long n, r;
  int kas;
  seive();
  scanf("%d", &kas);
  for (int t = 0; t < kas; t++) {
    scanf("%I64d", &n);
    r = sqrt(n);
    if ((r * r == n) && (ar[r] == 0)) {
      printf("YES\n");
    } else {
      printf("NO\n");
    }
  }
  return 0;
}
