Given a tree of N nodes, the task is to find the node having maximum depth starting from the root node, taking the root node at zero depth. If there are more than 1 maximum depth node, then find the one having the smallest value.
Input: 1 / \ 2 3 / \ 4 5 Output: 4 Explanation: For this tree: Height of Node 1 - 0, Height of Node 2 - 1, Height of Node 3 - 1, Height of Node 4 - 2, Height of Node 5 - 2. Hence, the nodes whose height is maximum are 4 and 5, out of which 4 is minimum valued. Input: 1 / 2 / 3 Output: 3 Explanation: For this tree: Height of Node 1 - 0, Height of Node 2 - 1, Height of Node 3 - 2 Hence, the node whose height is maximum is 3.
- The idea is to use Depth First Search(DFS) on the tree and for every node, check the height of every node as we move down the tree.
- Check if it is the maximum so far or not and if it has a height equal to the maximum value, then is it the minimum valued node or not.
- If yes then update the maximum height so far and the node value accordingly.
Below is the implementation of the above approach:
- Count nodes from all lower levels smaller than minimum valued node of current level for every level in a Binary Tree
- Difference between sum of even and odd valued nodes in a Binary Tree
- Depth of the deepest odd level node in Binary Tree
- Replace node with depth in a binary tree
- Replace every node with depth in N-ary Generic Tree
