Use a min heap of size k to find the k min elements.
Use quickselect algorithm to find the kth smallest element and return first k elements smaller than it.
- Q2. Find that given tree is BST or not.
- Ans.
Check if a given tree is a Binary Search Tree (BST) or not.

Check if the maximum value in the left subtree is less than the root and the minimum value in the right subtree is greater than the root.
Use recursion to check if all subtrees are BSTs.
Time complexity: O(n), Space complexity: O(h) where h is the height of the tree.
- Q3. Find pair in BST with given sum
- Ans.
Given a BST and a sum, find a pair of nodes whose values add up to the given sum.
Traverse the BST in-order and store the nodes in a list
Use two pointers approach to find the pair with the given sum
If the sum is less than the current pair, move the right pointer to the left
If the sum is greater than the current pair, move the left pointer to the right
If the sum is equal to the current pair, return the pair
