WebTopological Sort Algorithm. Now that we’ve looked at Kahn’s Algorithm for topological sorting in detail with an example, we can condense it as the topological sort algorithm: Step 0: Find indegree for all nodes. Step 1: Identify a node with no incoming edges. Step 2: Remove the node from the graph and add it to the ordering.
