AVL tree
Consider following statements: S1: Rotation operation in AVL always preserves the Inorder ordering. S2: The median of all elements in AVL tree is always at root or one of its two children. S3: If every node in BST has either 0 or 2 children,then searching is O(logn) S4: In a 3 array tree. If number of internal node is 20 then number of Leaves are 41. True Statements ? Ans: Only S1 and S4

AVL Tree
Minimum number of internal nodes in an AVL tree with height 5? Please give a standard procedure that can be applied to larger heights as well. I know the formula: S(h) = S(h1) + S(h2) + 1, but here it is asked for internal nodes only. Drawing a tree is tedious.

AVL Tree
Suppose we have an AVL tree of n nodes and any change in the tree violates the AVL tree property then : S1: If we insert an element in the tree, maximum 2 Rotations are required to make the Tree AVL again. S2: If we delete an element from the tree, maximum 2 Rotations are required to make tree AVL again Which are correct statements?
