A Blog about Programming,Algorithms,Coding Competitions, and Discrete Mathematics!
- C++ I/O. Note: Be very careful when you use getline after using cin! The first getline may return an empty line (why?)
- Another I/O tutorial by Yury Kholondyrev (warmingup).
- C++ STL (vectors, lists, sets, maps, pairs) and algorithms. Part 1, Part 2, and Part 3.
- Graph algorithms (BFS, colored DFS, shotest paths, union/find, spanning trees, Euler paths, flow and matching). Part 1, Part 2, Part 3, Part 4, and Part 5.
