WebApr 12, 2024 · The KMP algorithm is an efficient string matching algorithm due to Donald Knuth, Vaughan Pratt, and James H. Morris. It is a linear time algorithm that exploits the observation that every time a match (or a mismatch) happens, the pattern itself contains enough information to dictate where the new examination should begin from.

We search … WebHow do you explain KMP algorithm in very simple terms? The idea behind KMP is “recovering” from mismatches by using partial match information to skip over positions where the needle can’t possibly be found and avoid redoing comparisons where we already know that a prefix of the needle matches the haystack.
