We saw that neither brute force string searching nor Rabin-Karp string searching
are effective. However in order to improve some algorithm, first we
need...

Brute force string matching
is a very basic sub-string matching algorithm, but it’s good for
some reasons. For example it doesn’t require preprocessing...
