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

What are the compile options for Rust, particularly the optimization level? When will be the next update? |

time limit is 21s and I got AC in 0.00s. is it because the server is much stronger than 15 years ago ? or the test cases are too weak ? |

Works with just fermant's with 20 iterations and by taking care of overflow during multiplications |

Carmichael numbers may be giving you WA. Read this https://crypto.stanford.edu/pbc/notes/numbertheory/millerrabin.html |
