Lowest Common Ancestor of Deepest Leaves | Binary Tree DFS | Java Python C++

Learn how to find the Lowest Common Ancestor (LCA) of the Deepest Leaves in a Binary Tree using an efficient DFS + Recursion approach. In this video, we solve the LCA of Deepest Leaves problem step by step and understand how to compare the depth of the left and right subtrees to identify the correct LCA. Topics Covered: LCA of Deepest Leaves Lowest Common Ancestor Binary Tree DFS Binary Tree Recursion Finding deepest leaves DFS tree traversal Recursive Binary Tree solution LeetCode 1123 C++, Java & Python implementation Time and Space Complexity Time Complexity: O(N) Space Complexity: O(H), where H is the height of the tree. For a balanced tree, recursion space is O(log N), while for a skewed tree it can be O(N).
