Math::DyckWords - Perl module for generating Dyck words. Dyck words are named after the mathematician Walther von Dyck. River stage one • 1 direct dependent • 1 total dependent

Dyck words are even numbered string of X's and Y's, or 0's and 1's, or any other binary alphabet for that matter, such that no initial segment has more Y's or 1's. The following are the Dyck words of length 2n where n = 3: 000111 010011 010101 001101...
