WebNov 1, 2024 · Program to print the DFS traversal step-wise using C++ C++ Server Side Programming Programming In this tutorial, we will be discussing a program to print the steps of the traversal using Depth First Search in a given binary tree. This would include every step that occurs in the depth-first search including the backtracking procedure as well. WebAnswer: The first step is to realize C++ doesn't have a 2-D vector. You can use a [code ]std::vector>[/code], but you have to be mindful of the fact it's not a rectangular 2-D array. In fact, not everyone is a fan of vector-of-vectors. In this answer, I link to code for a DFS maze...
