WebOct 9, 2016 · Find the number of comparisons made by Horspool's string search algorithm in the following case: String: 001001001001. Pattern: 111. Attempt 1. The shift table value … WebThe best and average-case performance of this algorithm is O(n/m) (since only 1, or some small constant number out of every m characters of t needs to be checked). So, somewhat counter-intuitively, the longer that p is, the faster we will likely be able to find it. The worst-case performance of the algorithm is approximately O(nm).
