Web- If this Block has children then: - their maxDepth is the same as the one of this Block - their size is half that of this Block - their level is one greater than that of this Block - the position of their upper left corner can be determined from their size and the position of the upper left corner of this Block (I'll leave it up to you to figure out how). - the color of this Block is null ...

WebTo find the maximum depth of the tree we can apply a simple recursive approach. Where each function call will represent a subtree which has root node called as ‘root’. We traverse the tree by a recursive function starting from the root node. So the base case is when the subtree is empty i.e. root is NULL. So we return depth as 0. Web16 feb. 2024 · The brute force approach to finding the maximum depth of a binary tree would be to traverse the entire tree and count the maximum depth. We can perform this traversal using DFS. Algorithm: If the root is null, return 0. Otherwise, recursively find the maximum depth of the left subtree and right subtree.
