Algorithm libraries

This repository contains my implementation for various algorithms.

My implementation is targeted at ACM or Olympiad in Informatics, so don't tell me about bad code style or they are not generic.

Current implementations:

• rsort: sort int blazing fast

• fastio: IO with unsigned, blazing fast

• fastrand: xorshift RNG, very fast

• treap: balanced binary search tree, with insert, delete, rank and select

• nt: various number theory algorithms

• str: various string manipulation algorithms
