WebMar 23, 2014 · 1 In school, when we need to iterate through a tree (e.g. binary search tree), we were always taught to iterate through the tree recursively. Since every recusion can … WebA Depth–first search (DFS) is a way of traversing graphs closely related to the preorder traversal of a tree. Following is the recursive implementation of preorder traversal: procedure preorder (treeNode v) { visit (v); for each child u of v preorder (u); } To turn this into a graph traversal algorithm, replace “child” with “neighbor”.

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 ...

The idea is to traverse the tree in a postorder fashion and delete the left and right subtree of a node before deleting the node itself.
