Options:

Correct Answer: Depth First Search

Solution:

Topological sorting can be performed using Depth First Search (DFS) on a directed acyclic graph.

Which of the following algorithms is used for topological sorting in a directed acyclic graph (DAG)?

Step 1: Understand what a directed acyclic graph (DAG) is. A DAG is a graph that has directed edges and does not contain any cycles.
Step 2: Learn about topological sorting. It is a way of arranging the nodes of a DAG in a linear order such that for every directed edge from node A to node B, node A comes before node B in the ordering.
Step 3: Familiarize yourself with Depth First Search (DFS). DFS is an algorithm for traversing or searching through a graph by exploring as far as possible along each branch before backtracking.
Step 4: Realize that to perform topological sorting using DFS, you start at any node and explore as far as possible down each path, marking nodes as visited.
Step 5: Once you reach a node with no unvisited neighbors, you add it to the topological order. You repeat this process until all nodes are visited.
Step 6: The final order you get after visiting all nodes will be the topological sorting of the DAG.
