Learning Algorithms: Never getting any better
I want to implement algorithms and data structures for practice. I have a bunch of textbooks I am working through and although I can understand the idea and theories I can never seem to close the book and implement working code on my own, like people do in ACM programming contests. I can learn how to write a linked list in C, and forget...

Which language is better suited for a programming competition: Java or C++?
Hi! I'd like to know which one is more suitable for programming contests, online judges. I don't want answers like "go with java" or "c++ is the fastest". I'd like to know that in more details, lets say like "95% of the time you wont need to write in c++, java solution will get accepted too" or "java has BigInteger object and c++ doesn...
