2025年1月6日 · The article explains how to convert a binary tree into its mirror tree by swapping the left and right children of all non-leaf nodes using both recursive and iterative approaches.

2023年3月26日 · Given a binary tree, the task is to convert the binary tree to its Mirror tree. Mirror of a Binary Tree T is another Binary Tree M(T) with left and right children of all non-leaf nodes interchanged. Example 1: Explanation: In the inverted tree, every non-leaf node has its left and right child interc

Given a binary tree, convert the binary tree to its Mirror tree. Mirror of a Binary Tree T is another Binary Tree M(T) with left and right children of all non-leaf nodes interchanged. Examples: Input: root[] = [1, 2, 3, N, N, 4]

Given the root node of a binary tree, swap the ‘left’ and ‘right’ children for each node. The below example shows how the mirrored binary tree should look like.

2024年9月30日 · Given a binary tree, our task is to convert this binary tree into its mirror tree. A mirror tree is another form of a binary tree where the left and right children of all non-leaf nodes are interchanged. Example of Mirror Tree. Let us try to mirror the following binary tree:

2023年11月19日 · Given a binary tree, write an efficient algorithm to convert the binary tree to its mirror... The idea is to traverse the tree in postorder fashion and for every node we swap its left and right child pointer after recursively converting its left subtree and right subtree first to mirror.

2025年1月21日 · Given a binary tree, the task is to check whether it is a mirror of itself. Example: Input: Output: True Explanation: As the left and right half of the above tree is mirror image, tree is symmetric. Input: Output: False Explanation: As the left and right half of the above tree is not the mirror image, tree is not symmetric.

2019年3月20日 · I'm trying to write a recursive function mirror() in my Tree class that will return a mirrored version of the tree (left and right nodes swapped). So if I call this function on a Tree t, I would expect to start from the root, and swap all of the nodes until we reach a node that has no more children to swap.

1. For creating a mirror image of a tree, we need to traverse the subtrees. 2. While traversing the subtrees we have to swap the left and the right child of all the nodes. 3. After swapping the left and the right child of all the nodes the tree which we will obtain, will be the mirror image of the original tree which was taken as an input.

Given 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
