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

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
