Q. Implement the String Match KMP algorithm.
Ans. 

The KMP algorithm is used for pattern matching in strings.

  • KMP algorithm avoids unnecessary comparisons by utilizing a prefix-suffix table.

  • It has a time complexity of O(n + m), where n is the length of the text and m is the length of the pattern.

  • The algorithm is efficient for large texts and patterns with repetitive characters.

  • Example: Searching for 'abc' in 'ababcabc' using KMP algorithm will return the index 2.

  • Sort the array to simplify finding triplets. Example: [-1, 0, 1, 2, -1, -4] becomes [-4, -1, -1, 0, 1, 2].

  • Use a loop to fix one element and apply two-pointer technique for the remaining elements.

  • Skip duplicates to ensure unique triplets. For instance, if the current element is the same as the previous, continue.

  • Return a list of unique ...
