Horspool python
WebJun 15, 2024 · The core idea of Horspool algorithm is to improve the movement of the pattern matching window by using space to exchange time. Unlike a brute-force algorithm, the pattern matches from right to left and is stored in the table by pre-calculating the distance of each move. The code is as follows: WebMay 9, 2024 · Horspool is a simplified version of Boyer-Moore (with only a bad character rule) and uses smaller internal tables. The average complexity is linear, but the worst-case might be O (mn). In Boost You might be familiar with …
