Mr. Retardo has lost his marbles. He's a professor, and absolutely loathes his students. And since going full retard, he asks them all sorts of useless questions. His latest obsession is prime numbers, and he gives all his a students random number n and asks them to check if it is prime. 
Check if it is!!
