String Algorithms
String Fundamentals
String algorithms are essential for text processing, pattern matching, and data analysis. Understanding efficient string operations is crucial for many applications.
Pattern Matching
Finding occurrences of a pattern in a text. Naive approach: O(nm) where n is text length and m is pattern length.
KMP Algorithm
Knuth-Morris-Pratt algorithm improves pattern matching to O(n+m) using failure function to avoid unnecessary comparisons.
Common String Problems
- Longest Common Substring
- Longest Palindromic Substring
- String Compression
- Anagram Detection
