1. [10 pts.] AVL Trees: Example Operations
(a) [5 pts.] Draw the AVL tree that results from inserting key
45 into the following AVL
tree.
(b) [5 pts.] Draw the AVL tree that results from deleting key 70
from the following AVL
tree. NOTE: When deleting a key from an AVL tree, please follow the
textbook approach
of finding the node with the key using the function for standard
binary search trees.
If the key is in the tree and the node w where the key is found
does not have any
child pointing to NULL/none, then use the implementation of the
algorithm that finds
the successor node x to node w in an inorder traversal of the
binary search tree, and
copies the entry information (i.e., not including the children or
parent pointers) from x
to w (e.g., the key and value stored at node x becomes that of node
w). That algorithm
then deletes node x from the AVL tree and perform any required
balancing by properly
restructuring the tree.

3. (8 points) Using the implementation of binary search tree operations we discussed in class, draw the trees that result from the following operations: (a) Inserting 142, 400, 205, 127, 100, 320, 160, 141, and 110 into an initially-empty tree (in that order). (b) Deleting 142 from the tree you drew for part (a). 4. (8 points) Draw the unique binary tree that has a preorder traversal of 4, 1, 6, 3, 7, 5, 9, 2, 8 and an inorder...
