Add KMP Substring Search Algorithm

[pandeysubash404]

Adding more code file required for #219

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.

I encountered an error during the 'build-and-analyze' process related to the test case RandomNumberTest > testGetRandomNumber():

RandomNumberTest > testGetRandomNumber() FAILED
    org.opentest4j.AssertionFailedError at RandomNumberTest.java:60

Since this issue seems unrelated to my changes, could you please advise on the next steps? I believe the failure may be due to an existing issue in the test or an external factor.

Thanks for your assistance!

Looks like flaky RandomNumberTest.java so no worries on your side. I re-ran the build and everything passed.

Looks good! Thank you for the contribution 🎉
