DSA - Level 1 - Iterative Depth First Traversal | Iterative DFS in Graphs | DFS Code

Please consume this content on nados.pepcoding.com for a richer experience. It is necessary to solve the questions while watching videos, nados.pepcoding.com enables that. NADOS also enables doubt support, career opportunities and contests besides free of charge content for learning. This video discusses the iterative approach of Depth First Search or Depth First Traversal in Graphs. At the end of this video, we compare the recursive and iterative approach for DFS and discuss the code where we required to travel iteratively using DFS in Graphs. We state the problem where: 1. You are given a graph, and a source vertex. 2. You are required to do a iterative depth first traversal and print which vertex is reached via which path, starting from the source. Note - For output, check the sample output and question video. Iterative depth first traversal should mimic "Reverse preorder" i.e. neighbor with highest value should be visited first and should be printed on the way down in recursion.
