WebMar 13, 2024 · The matching characters are determined, first by finding the longest common substring (LCS) and then, recursively, finding the matching characters (using LCS again) in the non-matching regions of both strings. We illustrate this algorithm with the example used in the original algorithm using the words ‘Pennsylvania’ and ‘Pencilvaneya’. WebApr 1, 2011 · Pattern searching is an important problem in computer science. When we do search for a string in a notepad/word file or browser or database, pattern searching algorithms are used to show the search results.
