      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?
      A From the beginning of the pattern. Correct Answer Incorrect Answer
      B From the middle of the pattern. Correct Answer Incorrect Answer
      C From the end of the pattern. Correct Answer Incorrect Answer
      D Randomly chooses a starting point. Correct Answer Incorrect Answer
      E From the beginning of the text. Correct Answer Incorrect Answer

      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.
