WebWe need to find the kth largest element, we can first find the total number of nodes in the tree and then subtract the k-1 from the total number of nodes. Now we find n-k+1 smallest node, where n is the total number of nodes in the binary search tree. But this approach will require two passes or two traversals over the tree. WebMethod 2: Using median. In this problem, the given Binary Search Tree is perfect and we also know the number of the nodes, i.e., N. We can use these two pieces of information to get a more efficient solution than Method 1 and reduce the time complexity factor from O (N) to O (logN). The given BST being perfect, will always have an odd number of ...
