(b) A binary search tree contains the following keys: 18, 1, 3, 42, 35, 8, 14, 23, 1, 11, 55, 91. If the keys in the tree are printed using inorder traversal, what is the output sequence printed? 4 + 4 points Solution: Many of you actually constructed the binary search tree and then traversed the tree in order to get the output. A short-cut is to write sort the list above (since the inorder traversal of a BST gives a sorted sequence.)
