How does the Rabin-Karp algorithm handle potential spurious matches?

  • It adjusts the length of the search window dynamically to avoid spurious matches.
  • It ignores potential spurious matches and relies on a post-processing step to filter them out.
  • It rehashes the entire text for each potential match to verify its accuracy.
  • It uses a rolling hash function to efficiently update the hash value of the current window.
The Rabin-Karp algorithm handles potential spurious matches by using a rolling hash function. This allows it to efficiently update the hash value of the current window in constant time, reducing the likelihood of false positives.
