Given a Binary Tree and a Level. The task is to find the node with the maximum value at that given level.
The idea is to traverse the tree along depth recursively and return the nodes once the required level is reached and then return the maximum of left and right subtrees for each subsequent call. So that the last call will return the node with maximum value among all nodes at the given level.
Below is the step by step algorithm:
- Perform DFS traversal and every time decrease the value of level by 1 and keep traversing to the left and right subtrees recursively.
- When value of level becomes 0, it means we are on the given level, then return root->data.
- Find the maximum between the two values returned by left and right subtrees and return the maximum.
Below is the implementation of above approach:
- Find maximum level sum in Binary Tree
- Find maximum level product in Binary Tree
- Find the node with maximum value in a Binary Search Tree
