Constructive Algorithm Techniques

Constructive algorithms build a valid answer directly by following a recipe, rather than searching exhaustively.

Fix One Variable Technique

The Fix One Variable technique reduces multi-variable search problems by enumerating one variable explicitly and optimizing over the others with structure.

Invariant Maintenance

An invariant is a property you promise to keep true throughout an algorithm, and it is the anchor of both design and correctness proofs.

Greedy Algorithms

Greedy algorithms build a solution step by step by always taking the best local choice available.

Two Pointers

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

Monotonic Deque

A monotonic deque is a double-ended queue that keeps elements in increasing or decreasing order so that the front always holds the current optimum (min or max).
