Find k-th smallest element in Binary Search Tree

WebUsing the position of the median, we can locate or find out the Kth smallest element. If the position of the median is equal to K, it gives the value of Kth smallest element. If the position of the median is less than K, it refers to the fact that the Kth smallest element is in the left subtree of the current median. WebTo find the k'th smallest node, we can perform inorder traversal and store the inorder sequence in an array. Then the k'th largest node would be the (n-k)'th smallest node, …
