CodeChef solutions and tidbits...

What is this?

A collection of my solutions to competitive programming questions.

Can I use this?

Sure, just follow the GPL license (and keep in mind that plagiarising source codes for contests would essentially disqualify you).

How do I use this?

The file name is the code for the question on the site. That's all.

What can I use this for?

Practice, improving your solutions, not a lot.

What does "ios_base...." mean?

A standard CP method to enable fast I/O. See https://stackoverflow.com/questions/31162367/significance-of-ios-basesync-with-stdiofalse-cin-tienull for exact clarification. It IS C++-specific.

Why do I use C++ only?

Because it is the best option for CP. C++ comes with STL (Standard Template Library) while most do not. Remember that other languages might offer better options depending on the solution required. Other popular languages for CP are Java, C and Python, do check them out.

What are some good sites to get into CP?

CodeChef, Codeforces, Topcoder, Project Euler... the list goes on.
