- Q1. Topological Sort Implementation
- Ans.
Topological sort is a linear ordering of vertices in a directed acyclic graph.
Topological sort is used to find a linear ordering of vertices in a directed acyclic graph.
It is commonly implemented using depth-first search (DFS) algorithm.
The algorithm starts by visiting a vertex and then recursively visits all its adjacent vertices before adding it to the result list.
Topological sort is not possible if the graph has cyc
