Binary tree mirror image code
WebGiven the root of a binary tree, check whether it is a mirror of itself (i.e., symmetric around its center). Example 1: Input: root = [1,2,2,3,4,4,3] Output: true Example 2: Input: root = [1,2,2,null,3,null,3] Output: false Constraints: The number of nodes in the tree is in the range [1, 1000].-100 <= Node.val <= 100 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.

WebDownload Run Code Output: The binary tree is symmetric The time complexity of the above solution is O (n), where n is the total number of nodes in the binary tree. The program requires O (h) extra space for the call stack, where h is the height of the tree. Alternate Approach WebLet us now understand the following problem on binary trees. The problem statement is as follows - Given a binary tree, you need to construct a tree that is the same as the mirror image of the given tree. In the image below, we have a tree in which we have created the mirror image of the same.
