9 Part 1 In the Lecture related to the subject Binary search Trees, we have looked at the Algorithm proper to In-order Tree walk, this algorithm is so named because it prints the key of the root of a subtree between printing the values in its left subtree and printing those in its right subtree, we have illustrated it by an example to print the node's keys in a monotonically increasing order. Similarly, a preorder tree walk prints the root before the values in either subtree, and a postorder tree walk prints the root after the values in its subtree. Questions: 1. Write down the recursive algorithms that perform preorder and postorder tree walks on a tree of nodes. 2. 15 Apply in-order, preorder and postorde, tree walk on the following Binary search Tree Part 2 17 20 23 27 29 30 36 40 49 55 71 75 We have studied as well the Algorithm Tree- Successor that looks for the Successor of a given node, Write down the Algorithm for Tree- predecessor that looks for the predecessor of a given node, use the fact that tree-predecessor is symmetric to tree- successor to help you in writing down your solution. 95
