##Algorithms by Ishaan Sang:
Collection of different algorithms, used for programming competitions (like ACM ICPC).
Contains algorithms divided by topic. Most algorithms are runnable from the file as is. All algorithms have a reference problem on which they can be tested (or are waiting for this problem to be provided).
List of algorithms with some additional information is available at adilet.org/algos
