WebKMP algorithm is just like the naive algorithm when there is a match, but whenever there is a mismatch KMP algorithm uses LPS array of the pattern to decide what to do ahead. Let us take an example, text – “aaebcaaeaaebcaadaa” pattern – “aaebcaadaa” Output – “8” The LPS array for the pattern is {0, 1, 0, 0, 0, 1, 2, 0, 1, 2} WebJul 6, 2011 · 1 Answer. Sorted by: 2. from this site: The KMP algorithm preprocess the pattern P by computing a failure function f that indicates the largest possible shift s using previously performed comparisons. Specifically, the failure function f (j) is defined as the length of the longest prefix of P that is a suffix of P [i . . j].
