String Algorithm Matcher Skill

Purpose

Match string processing problems to the most appropriate algorithms based on requirements and constraints.

Capabilities

• Pattern matching algorithm selection (KMP, Z, Rabin-Karp)
• Suffix structure selection (array vs tree vs automaton)
• Palindrome detection algorithm selection
• Rolling hash implementation guidance
• String DP technique matching

Target Processes

• pattern-matching-algorithms
• trie-suffix-structures
• string-processing

Algorithm Selection Guide

Single Pattern Matching

| Scenario | Algorithm | Complexity | |----------|-----------|------------| | Single pattern | KMP | O(n+m) | | Multiple patterns | Aho-Corasick | O(n+m+z) | | Approximate match | Rolling Hash | O(n*m) average |

Suffix Structures

| Need | Structure | Build Time | |------|-----------|------------| | Substring search | Suffix Array | O(n log n) | | Multiple queries | Suffix Tree | O(n) | | Subsequence counting | Suffix Automaton | O(n) |

Palindromes

| Problem | Algorithm | |---------|-----------| | Longest palindromic substring | Manacher | | Palindrome partitioning | DP + Manacher | | Palindrome queries | Hashing |
