math/libdivsufsort 2.0.2.1.20151027 DragonFly

libdivsufsort is a software library that implements a lightweight suffix array construction algorithm.

This library provides a simple and an efficient C API to construct a suffix array and a Burrows-Wheeler transformed string from a given string over a constant-size alphabet. The algorithm runs in O(n log n) worst-case time using only 5n+O(1) bytes of memory space, where n is the length of the string.
