Arya C. - "Idea: Time complexity: O(n) each node visited once Space complexity: O(h) recursion stack For each node, we want to verify: Descendants here means all nodes in the subtree excluding the node itself. We do a post-order traversal (process children before the node itself). For leaf nodes, there are no descendants, so they are valid by definition. For internal nodes: Recursively compute the sum and count of nodes in the left and right subtrees. Calculate the total sum and"See full answer
