Dfs based topological sort
WebOct 27, 2014 · Theoretically, every node in the graph could have a self pointing edge, then there'll be n cycles. However, an easy approach would be to grab any edge in the graph, then iterate over it until you reach back to the same edge, and output this as a cycle. Edges which result in dead-ends should be removed, and any cycle found should remove all the ... WebNov 7, 2024 · 14. 4.1.1. Depth-first solution ¶. A topological sort may be found by performing a DFS on the graph. When a vertex is visited, no action is taken (i.e., function PreVisit does nothing). When the recursion pops back to that vertex, function PostVisit prints the vertex. This yields a topological sort in reverse order.

Here we are implementing topological sort using Depth First Search. 1. Step 1: Create a temporary stack. 2. Step 2: Recursively call topological sorting for all its adjacent vertices, then push it to the stack (when all adjacent vertices are on stack). Note this step is same as Depth First Search in a recursive way. 3. Step 3: … See more The pseudocode of topological sort is: 1. Step 1:Create the graph by calling addEdge(a,b). 2.
