Understanding the KMP String Matching Algorithm with Implementation and Optimizations

This article explains the Knuth-Morris-Pratt (KMP) string‑matching algorithm, describes how the next array is built to capture prefix‑suffix information, shows Java implementations of the search and next‑array construction, and discusses common optimizations to reduce redundant comparisons.

Understanding Brute‑Force, Boyer‑Moore, and KMP String‑Matching Algorithms with Java Code

This article explains the Brute‑Force (BF), Boyer‑Moore (BM), and Knuth‑Morris‑Pratt (KMP) string‑matching algorithms, illustrates their operation with step‑by‑step visual examples, discusses the inefficiencies of BF, the shift rules of BM, and the prefix‑suffix logic of KMP, and provides a complete Java implementation including the construction of the next array.
