· 3 pulled
Popular programming languages provide methods or functions which locate a substring in a given string.
During past decades several algorithms to solve this problem were designed.
Basically these algorithms could be split into two major categories: (1) based on Deterministic Finite Automaton, like Knuth-Morris-Pratt, Boyer Moore, etc., and (2) based on a simple comparison, like the Karp-Rabin algorithm.
Snippet from the RSS feed
Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr, the C++ class std::string has the method find, Python's string has methods pos and index, and so on, so forth. All these
