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
