Leetcode Problem 230. Kth Smallest Element in a BST
Leetcode Solutions
Iterative Inorder Traversal
- Initialize an empty stack.
- Start from the root node and go to the leftmost node using a while loop, pushing all the nodes onto the stack.
- Once you reach the leftmost node, start popping elements from the stack.
- For each popped element, increment a count to keep track of how many elements have been visited.
- If the count equals k, return the value of the node.
- Move to the right subtree of the popped node and repeat the process from step 2.
- Continue this process until the kth smallest element is found.
