Invert Binary Tree (LeetCode 226) | Full solution with diagrams and animations | Study Algorithms

Inverting a binary tree is more synonymous with mirroring a binary tree. Try to assume that there is a mirror in front of the tree and you need to return the reflection. This video explains beautifully with diagrams and animations how the reflection looks like and how to create one. All of this is done using a level order traversal technique.
