C program to implement KnuthMorrisPratt algorithm(KMP String Matching) Knuth-Morris-Pratt algorithm keeps the information that nave approach wasted gathered during the scan of the text. By avoiding this waste of information, it achieves a running time of O(n m), which is optimal in the worst case sense. Knuth-Morris-Pratt algorithm is based upon forward pattern matching and Boyer-Moore is based upon backward pattern matching.1.
