Two Pointers

Two pointers is a pattern where two indices move through a sequence in a coordinated, usually monotonic way to avoid unnecessary work.

Aho-Corasick - DP Applications

Aho–Corasick (AC) turns a set of forbidden patterns into a finite automaton that lets you process or generate strings while tracking whether any pattern appears.

Li Chao Tree

A Li Chao tree maintains a set of lines y = m x + b and answers minimum (or maximum) value queries at a given x in O(log C) time, where C is the numeric range of x.

Palindromic Tree (Eertree)

A Palindromic Tree (Eertree) stores every distinct palindromic substring of a string as a node and can be built online in linear time.

Suffix Automaton - Advanced Usage

A suffix automaton (SAM) is a compact DFA that captures all distinct substrings of a string and supports many advanced queries in linear time.

Suffix Automaton

A suffix automaton (SAM) is the minimal deterministic finite automaton that recognizes all substrings of a string, built online in O(n) time and space.

Aho-Corasick Automaton

Aho–Corasick is a trie with failure links that finds all occurrences of many patterns in a single pass over the text.

Suffix Array - LCP Array Applications

The LCP (Longest Common Prefix) array, built alongside a suffix array, unlocks fast solutions to problems like longest repeated substring, number of distinct substrings, and longest common substring.

Euler Tour Tree

An Euler Tour Tree represents each rooted tree as a DFS open/close sequence so that every subtree is a single contiguous interval.
