Knuth-Morris-Pratt (KMP) algorithm utilizes a _______ to optimize the search process.
- Backtracking mechanism
- Dynamic programming table
- Failure function
- Greedy approach
The Knuth-Morris-Pratt (KMP) algorithm utilizes a failure function (also known as the longest prefix suffix array) to optimize the search process. The failure function is precomputed based on the pattern and helps the algorithm determine the maximum length of a proper suffix that matches a proper prefix within the pattern. This information is then used to efficiently skip unnecessary comparisons during the search.
