Hi kana you should print a blank line between the output lines of two consecutive inputs.Here is an example for you.

Input : Output : Hope it will work.Good Luck...

Hi shimon you should rather precalculate all primes instead of using your Isprime() so many times.You can use sieve method to determine all primes before you start taking input.Then just check through only the prime nubers.I hope it will work. Good Luck.
