WebIn recursive DFS traversal of binary tree, we have three basic elements to traverse: root node, left subtree, and right subtree. Each traversal process nodes in a different order using recursion, where recursive code is … WebMar 12, 2024 · Recursive Approach: The idea is to traverse the tree in a Level Order manner but in a slightly different manner. We will use a variable flag and initially set it’s value to zero. As we complete the level order traversal of the tree, from right to left we will set the value of flag to one, so that next time we can traverse the Tree from left ...
