Added Suffix Array + LCP + Pattern Search

[utam-1]

Summary of changes made

• Added a new program: string_suffix_array_lcp_search.c

• Demonstrates construction of Suffix Array and LCP (Longest Common Prefix) arrays for a given string.

• Includes binary-search-based pattern search using the suffix array for efficient substring matching.

• Fully commented with detailed explanations — serves as a mini-tutorial for learners exploring advanced algorithms in C.

Why This Program?

This program fills the gap between basic examples (like sorting, searching, and data structures) and real-world algorithmic applications that demand C-level efficiency.

Key Features

Suffix arrays are a fundamental data structure in string processing, with applications in text indexing, genome analysis, and full-text search engines. What makes this program stand out is its:

• Beginner-friendly approach with modular functions and clear logic
• Rich inline comments that provide a step-by-step explanation of each concept
  This makes it an ideal resource for those looking to learn and apply efficient string processing techniques.

@gouravthakur39 I liked the idea of this repo, and would like to contribute in it with the help of the following program. It'll help students learn various concepts related to structures, pointers, etc. Let me know if it is good enough to be added on this repo, or if I should make any changes.
