rabin karp Algorithm

In computer science, the Rabin – Karp algorithm or Karp – Rabin algorithm is a string-searching algorithm created by Richard M. Karp and Michael O. Rabin (1987)In contrast, the Aho – Corasick algorithm can find all matches of multiple shapes in worst-case time and space linear in the input length and the number of matches (instead of the total length of the matches).
