Exercise 1:

List the elements of the following binary tree in pre-order, in-order and post-order traversals: See image.

Exercise 2:

Consider insertion of the following sequence of integers into an empty AVL Tree:

1 2 3 4 5 6 7 9 8
(Notice that 9 precede 8 in the input sequence!)

Draw the corresponding AVL Tree after the completion of each insertion that requires a rotation. If an insertion requires double-rotation, then draw the tree after the first rotation as well as after the second rotation.

Exercise 3:

Draw the AVL tree that would result after deleting V and then deleting F from the following AVL tree. See image.
