Binary Tree Upside Down– LeetCode Problem

**Problem:**

Given a binary tree where all the right nodes are either leaf nodes with a sibling (a left node that shares the same parent node) or empty, flip it upside down and turn it into a tree where the original right nodes turned into left leaf nodes. Return the new root.

For example:

Given a binary tree {1,2,3,4,5},

1 / 2 3 / 4 5

return the root of the binary tree [4,5,2,#,#,3,1].

4 / 5 2 / 3 1

Binary Tree Upside Down– LeetCode Solutions

Binary Tree Upside Down Solution in C++:

class Solution { public: TreeNode* upsideDownBinaryTree(TreeNode* root) { if (!root || !root->left) return root; TreeNode* newRoot = upsideDownBinaryTree(root->left); root->left->left = root->right; // 2's left = 3 (root's right) root->left->right = root; // 2's right = 1 (root) root->left = nullptr; root->right = nullptr; return newRoot; } };

Binary Tree Upside Down Solution in Java:

class Solution { public TreeNode upsideDownBinaryTree(TreeNode root) { if (root == null || root.left == null) return root; TreeNode newRoot = upsideDownBinaryTree(root.left); root.left.left = root.right; // 2's left = 3 (root's right) root.left.right = root; // 2's right = 1 (root) root.left = null; root.right = null; return newRoot; } }

Binary Tree Upside Down Solution in Python:

class Solution: def upsideDownBinaryTree(self, root: Optional[TreeNode]) -> Optional[TreeNode]: if not root or not root.left: return root newRoot = self.upsideDownBinaryTree(root.left) root.left.left = root.right # 2's left = 3 (root's right) root.left.right = root # 2's right = 1 (root) root.left = None root.right = None return newRoot
