Horspool's algorithm
WebUsing it alone produces a very efficient algorithm in practice. Horspool proposed to use only the bad-character shift of the rightmost character of the window to compute the shifts in the Boyer-Moore algorithm. The preprocessing phase is in O (m+sigma) time and O (sigma) space complexity. WebMar 5, 2024 · Use horspool algorithm to find first instance of pattern in overall string.
