Adding more code file required for #219 - @iluwatar
Implements the Knuth-Morris-Pratt (KMP) algorithm to efficiently find the first occurrence of a pattern in a given text. Uses the Longest Prefix Suffix (LPS) array to minimize unnecessary comparisons, resulting in a time complexity of O(n + m).
kmpSearch("abxabcabcaby", "abcaby")returns 6 since the pattern"abcaby"starts at index 6.
