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.
Topological Sort PHP 7.4+ An ordering of nodes in a directed acyclic graph (DAG) such that for every directed edge u→v, node u appears before v in the ordering.
