WebFeb 16, 2024 · 1. Basically, there are two algorithms used for topological sort, described on Wikipedia. Kahn's algorithm works with any graph traversal, including BFS or DFS. Tarjan's algorithm, which is now the most well known, uses a "reverse DFS postorder" traversal of the graph. Postorder means you add a node to the list after visiting its children.

Algorithm: 1. Create a recursive function that takes the index of node and a visited array. 2. Mark the current node as visited and print the node. 3. Traverse all the adjacent and unmarked nodes and call the recursive function with index of adjacent node.
WebNov 20, 2024 · Depth-first search (DFS) lives an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as one root in the case of a graph) and explores than far as workable along each branch before backtracking. Here are some important DFS problems asked in Engineering Interviews: WebOct 23, 2015 · Approach: Depth-first search is an algorithm for traversing or searching tree or graph data structures.
