My name is Danilo and i'm from Kragujevac , Serbia. I am 15 years old.
I like mathematics and programming very much so i decided to sign in here. Even if i am better in programing i like mathematics also, and i like to solve math problems. I am actualy so good in programming that i represent my country on Junior Balkan Olympiad in Informatics (if anyone is contestant on JBOI 2012 this year let me know about it ).
I'm here also to help to anyone who has problems with programing.
