Brute‑Force and Simple Hash‑Based Substring Search (Rabin‑Karp) Explained with Examples

This article explains the brute‑force (BF) substring search algorithm, demonstrates its step‑by‑step operation with examples, then introduces a simple hash‑based sliding‑window method (a basic Rabin‑Karp approach), provides Java code, and shows how to compute and update hashes efficiently to locate a pattern in a main string.
