WebApproach. To 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’. … 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.
