String searching is the process of finding a specific sequence of characters, known as a substring, within a larger string of text. This technique is commonly used in computer science for tasks such as searching for keywords in documents, matching patterns in data, or even in programming languages for text manipulation. Various algorithms exist for string searching, including the Knuth-Morris-Pratt algorithm and the Boyer-Moore algorithm. These algorithms improve efficiency by minimizing the number of comparisons needed to locate the substring, making them essential for applications in search engines, text editors, and data processing systems.
