I though, by practicing using ruby in solving problems on that online
site, I’ll gain more knowledge. I also think that it’s a good approach
for beginners like me. And it’s one of many way to show that ruby is
also capable on this area.
So, I try to use ruby in solving some of the problems on that site but
sometimes I must come back to c/c++ for speed/time limit and input
Anyone have ever use ruby for this area? Could you give some tips for
ruby beginners in handling time limit and input processing problem.
