Topological Sort is an algorithm used to arrange the vertices of a directed acyclic graph (DAG) in a linear order. This order ensures that for every directed edge from vertex A to vertex B, vertex A comes before vertex B in the sequence. It is commonly used in scenarios like scheduling tasks, where certain tasks must be completed before others. The process of Topological Sort can be implemented using either Depth-First Search (DFS) or Kahn's algorithm. Both methods efficiently produce a valid linear ordering of the graph's vertices, making it a valuable tool in computer science for managing dependencies and optimizing workflows.
