Rabin-karp algorithm example
WebExample. The Rabin–Karp algorithm or Karp–Rabin algorithm is a string searching algorithm that uses hashing to find any one of a set of pattern strings in a text.Its average and best case running time is O(n+m) in space O(p), but its worst-case time is O(nm) where n is the length of the text and m is the length of the pattern. Webexpressed, for example, in terms of a percentage-match value or the length of the common portions. Neweyes employs a novel string matching algorithm, Running Karp-Rabin Greedy String Tiling (RKR-GST), which will be outlined below. (For a complete description, the reader should consult (Wise 1994).)
