Another Suffix Tree
September 10, 2003
Just yesterday I ran a pointer to some Suffix Tree code, not a particularly common occurrence here. It just happens that yesterday's article gives much credit to a Suffix Tree implementation by Shlomo Yona, which is pointed to here.
Shlomo's code is designed as a library, and includes some sample code to drive it, as well as some Perl code to make it easier to exercise.
