Solution: Find kth Maximum Value in Binary Search Tree
Let’s solve the Find kth Maximum Value in Binary Search Tree problem.
We'll cover the following
Statement
Given the root node of a binary search tree and an integer value k
, return the
Constraints:
The number of nodes in the tree is
n
.k
n
Solution
For this solution, we will recursively perform the inorder traversal (right subtree, root, left subtree) on the binary search tree. We will use the inorder traversal to get elements in sorted order.
While performing the inorder traversal on the tree, decrement
This approach ensures that we traverse the tree in a depth-first manner while appropriately updating k
and effectively finding the
Now, let’s look at the following illustration to get a better understanding of the solution:
