You could add "colors" to the nodes similar to the method done for recursive DFS found in CLRS, for example. WebReading time: 15 minutes Coding time: 5 minutes. Depth-first search (DFS) algorithm is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking.

WebGiven a binary tree, write an iterative and recursive solution to traverse the tree using inorder traversal in C++, Java, and Python. Unlike linked lists, one-dimensional arrays, and other linear data structures, which are traversed in linear order, trees can be traversed in multiple ways in depth–first order (preorder, inorder, and postorder) or breadth–first order …
