NAME

AlgorithmsIT - Provides some functions from Introduction to Algorithms, Third Edition

SYNOPSIS

use AlgorithmsIT :ALL;
use AlgorithnsIT::Classes;
my $P = ArrayOneBased.new: "abab";        # the pattern to be sought
my $T = ArrayOneBased.new: "abababcabab"; # text to search (target)
my @matches = KMP-Matcher $T, $P;         # find matches, if any
say @matches.gist;
# OUTPUT: «[0, 2, 7]␤»
# 0, 2, and 7 are shifts from the input's # first character to the match
# positions. The @matches array would be empty if no match were found.

Note the original version (v0.0.1) had an error in its implementation so it could not handle overlapping pattern matches. Later versions now work as its authors intended, thanks to Professor Cormen's reply to my erroneous bug report.

DESCRIPTION

AlgorithmsIT is a collection of a small subset of functions in Reference 1.
