Pick your input shape

Array

Contiguous memory. Index-based access. The foundation of everything.

String

An array of characters with its own grammar. Patterns, parsing, transformations.

Linked List

Nodes connected by pointers. Memory you don't see until you walk it.

Tree

Hierarchy made of nodes. Recursion's natural shape.

Graph

Nodes and edges. The most general shape — relationships everywhere.

Grid

2D arrays in disguise. Most matrix and pathfinding problems live here.
