Question 5 In computer science, a binary tree is a tree data structure in which each node has at most two children, which are referred to as the left child and the right child. (a) Consider the following set of data to be inserted sequentially into an empty binary search tree: 7, 3, 5, 1, 6, 2, 14, 4, 21, 18, 12 i. Draw the binary search tree. ii. Draw TWO (2) subtrees of the tree. iii. Write the order of the nodes visited in inorder traversal, preorder traversal and postorder traversal.
