WebFollowing is the structure used to represent the Binary Tree Node: class BinaryTreeNode {T data; BinaryTreeNode left; BinaryTreeNode right; public BinaryTreeNode(T data) {this.data = data; this.left = null; this.right = null;}} */ public class Solution {public static void mirrorBinaryTree(BinaryTreeNode root){//Your code … WebTo create a mirror image of a binary tree, we have to first clone the tree and then swap left and right pointer of every node of tree. Below is the structure of binary tree node. struct node { int data; struct node *left; struct node *right; }; Let "root" be the root pointer of given binary tree. If root is NULL, return NULL.
WebDec 16, 2024 · Symmetric Tree (Mirror Image of itself) In this post, iterative approach is discussed. We use Queue here. Note that for a symmetric tree elements at every level are palindromic. In example 2, at the leaf level, the elements are not palindromic. In other words, The left child of left subtree = right child of right subtree. WebOnce this is completed, just simply traverse the tree using the inorder traversal and the tree will be mirrored. Let us see this in a small example. Consider the following tree. 3 / \ 5 1 / \ / \ 6 2 0 8. Here root is 3. Enqueue it. Queue contains: [3] Initialize current-node to queue-front. current-node: 3.
WebGiven a binary tree, convert this binary tree into its mirror tree. A binary tree is a tree in which each parent node has at most two children. Mirror of a Tree: Mirror of a Binary Tree T is another Binary Tree M(T) with left and right children of all non-leaf nodes interchanged. Note: 1. Make in-place changes, that is, modify the nodes given a ...
