Flip binary tree leetcode

WebAn inversion, or mirror, of a Binary Tree (T), is just a Binary Tree M(T) whose left and right children (of all non-leaf nodes) are swapped. Algorithm. The solution is a simple recursive approach: Call invert for left-subtree. Call invert for right-subtree. Swap left and right subtrees. Code. The code snippet below implements the algorithm ... WebMay 14, 2024 · Given the root of a binary tree, flatten the tree into a "linked list": The "linked list" should use the same TreeNode class where the right child pointer points to the next node in the list and the left child pointer is always null. The "linked list" should be in the same order as a pre-order traversal of the binary tree.
