Heyo Codefoworcers! As I was practicing some of the problems, I came across the problem 1553C - Penalty and while solving this I literally blown up CF OJ and my Laptop!!!

The fact is my submission 280945613 gets AC while getting {warning: control reaches end of non-void function [-Wreturn-type]} this on my laptop and also this is not the end!

I ran this code on ideone.com it just works perfectly fine there as well, I literally don't have any idea about this. Even I changed compiler it still gets an AC. Drop your thoughts on it!
