Solution: Invert Binary Tree

Understand how to invert a binary tree by applying a post-order depth-first search traversal that swaps left and right subtrees. This lesson guides you through the algorithm and explains its linear time complexity and space considerations based on tree height.

We'll cover the following...

Statement

Given the root node of a binary tree, transform the tree by swapping each node’s left and right subtrees, thus creating a mirror image of the original tree. Return the root of the transformed tree.

Constraints:

  • 0≤0\leq Number of nodes in the tree ≤100\leq 100
