## PON - Prime or Not

Given the number, you are to answer the question: "Is it prime?"

Solutions to this problem can be submitted in C, C++, Pascal, Perl, Python, Ruby, Lisp, Hask, Ocaml, Prolog, Whitespace, Brainf**k and Intercal only.

### Input

t – the number of test cases, then t test cases follows. [t <= 500]
Each line contains one integer: N [2 <= N <= 2^63-1]

### Output

For each test case output string "YES" if given number is prime and "NO" otherwise.

### Example

```Input:
5
2
3
4
5
6

Output:
YES
YES
NO
YES
NO
```

 Alex Tran: 2014-06-30 03:53:46 my fermat primality implementation fails to recognize 32416187567 as prime.. Ashwini: 2014-06-28 08:13:21 @Simarpreet You will need to write a new function for multiplication too apart from powering. Just think for a moment and you will get it. Ashwini: 2014-06-28 08:09:06 AC in one go.. I can't believe :) My first randomised algo program.. Last edit: 2014-06-28 08:09:47 Soma: 2014-06-25 01:42:58 worth solving... my first problem solved using probabilistic method..../ learnt a lot.. simararorarox9: 2014-06-22 04:13:54 it really works.. just one doubt, I did this program in python because.. In c++ it will get out of range when i find square using fast exponentiation method taking modulo at each step..How to avoid it. ?
