Finally, we return the max(sum including root, sum excluding root), Time Complexity: O(N)Auxiliary Space: O(N). Example 1: Input: 1 / \ 3 2 / 4 Output: 2 Explanation: Minimum depth is between nodes 1 and 2 since minimum depth is defined as the numb. Example 2: if the parent is not selected, we will either select or not select this node; in either case, we pass that info to the children. Since each element in a binary tree can have only 2 children, we typically name them the left and right child. Hack-a-thon. The maximum sum of non-adjacent nodes including the node. It can be seen easily that the above approach can lead to solving the same subproblem many times, for example in the above diagram node 1 calls node 4 and 5 when its value is chosen and node 3 also calls them when its value is not chosen so these nodes are processed more than once. Job-a-Thon. Expected Time Complexity: O (N) 3. Note: Herespecial node is a node which is connected to exactly one different node. You will be notified via email once the article is available for improvement. We can solve this problem by considering the fact that both node and its children cant be in sum at the same time, so when we take a node into our sum, we will call recursively for its grandchildren or if we dont take this node then we will call for all its children nodes and finally we will choose maximum from both of the results.
