Algorithms terms
The step-by-step logic that powers efficient computation
Algorithms are the precise recipes that transform inputs into outputs efficiently. This category covers sorting, searching, graph traversal, dynamic programming, greedy approaches, divide-and-conquer, and complexity analysis. Understanding algorithmic thinking helps you recognise patterns in problems and reach for the right solution rather than reinventing a worse one.
Backtracking
An algorithmic technique that builds solutions incrementally, abandoning a path ('backtracking') when it determines the current path cannot lead to a valid solution.
