FM-index

This repository contains educational implementations of Burrows-Wheeler Tranformation and Ferragina-Manzini index.

The implementations are fully commented and the main goal is to provide clear implementations of BWT and FM-index.

Speed is considered secondary although there are different implementations with different algorithmic complexity.
