How many Binary Search Trees are possible for a labelled nodes?
Let us there are n nodes which are labelled. Then the number of trees possible is given by the Catalan Number i.e $\binom{2n}{n} / (n+1)$ Then the binary search trees possible is just 1?

When searching for the key value 50 in a binary search tree, nodes containing the key values 10,15,20,30,60,80,89,90 are traversed, not necessarily in the given order. How many different orders are possible in which these key values can occur on the search path from the root to the node containing the value 50?

MadeEasy Test Series: Programming & DS  Binary Search Tree
AVL tree is created by inserting the keys 2, 6, 1, 5, 3, 4, 7 in the given order (Assume the tree is initially empty). Then the level order traversals of the tree would be. 2, 1, 3, 5, 4, 6, 7 3, 2, 5, 1 ... . After 2 or 3 rotations I get stuck trying to figure out which way to rotate. Please help me with the proper steps in this question.

Gateforum Class Notes
Suppose we have a BST and we run a program on the BST with n leaf nodes and compute the value of a function $g(x)$ for each node in BST. If the cost of computing $g(x)$ is minimum of number of leaf node in left subtree and number of leaf node in right subtree. The worst case time complexity of the program is: $O(n)$ $O(nlog_2n)$ $O(n^2)^2$ $O(n^2log_2n)$

Balanced tree vs Complete binary tree
1. Please Verify this: Assuming pointer to node which need to be deleted given Balanced Binary Tree insertion = O(logn), deletion= O(logn) Complete Tree insertion = O(1), deletion= O(1) Assuming pointer to node which need to be deleted not given ... better than a complete binary tree for sorting a set S of n elements . Is it true if it is then reason please ?

Binary Tree
I have doubt when its asked to know number of labelled and unlabelled binary tree : For labelled = (On basis of labelling) T(n) = 2nCn/(n+1) * n! For unlabelled = (On Basis of Geometric Sturucture) T(n) = (2n)Cn/n+1 Right? What if its Asked for BST what will be the answer in both the above cases and Why?
