[Harshit-Chordiya]

Description

• Added Aho-Corasick String Search Algorithm and its relevant Tests
• Use a StringBuilder for result accumulation.
• Modify the matching method to return the number of states created.
• Improve variable naming and add comments for clarity.
• Added the AhoCorasickStringSearchAlgorithmTest class to work with the refactored code.
• Create separate instances of the algorithm for each test case to ensure independence.
• Add appropriate assertions to the test cases.

Type Of Change

Added a new Algorithm (Aho-Corasick String Search Algorithm).

Added Tests or not?

Yes, there is a separate file with 3 tests called AhoCorasickStringSearchAlgorithmTest file.

1. testTrial 1
2. testTrial 2
3. testTrial 3
