Question
The Boyer-Moore algorithm is known for its efficiency in
practice, especially for long patterns and large alphabets. It uses two heuristics: the bad character heuristic and the good suffix heuristic. Which direction does it typically start matching from?Solution
Unlike Naive and KMP algorithms, the Boyer-Moore algorithm starts comparing the pattern with the text from the rightmost character of the pattern. This allows it to make larger shifts when a mismatch occurs, leveraging its bad character and good suffix heuristics.
