Same Tree (LeetCode 100) | Full solution with visuals and animations | Study Algorithms

Two trees even if they are different can result in a same traversal result. This happens because of the non-linear structure of the tree data structure. A neat little trick can be applied to the level order traversal technique to determine if two trees are exactly the same. Watch this video to understand how you can take advantage of the actual structure of a tree node and arrive at a solution.
