Hey guys! Literally just started today, and trying to do problem 42.
I'm using C++ with clang-3.5 and it compiles fine on my computer, but the SPOJ compiler is complaining at me. Seems like it's not recognising some of the STL functions I use, namely std::to_string(x), and std::stoi(s).
So my question is, exactly what libraries you are actually allowed to use? Or am I doing something wrong? I trying using both clang-3.7 and C++ 5 settings on SPOJ.
