Thread: How to check!!

    How to check!!

    How to check whether a number is prime or not however it is arranged.
    e.g:- 113 , no matter how you arrange it, it will be prime, 131, 311, how to implement it in C# ??

    If something is prime it has no divisors other than 1 and itself. So write some code that checks for that
    Rotating digits in a number is a rather simple problem which can be solved using modulo, division and multiplication.

    Good luck with your Project Euler answers. I'd recommend trying to solve the problems yourself rather than getting others to do them for you. It kinda defeats the purpose otherwise
