Consider the tree structure in Figure 10: Figure 10 Which of the following is CORRECT? The tree above is a complete binary tree but not a full binary tree. The pre-order traversal of the tree above is 11,4,1,9,6,18,13,14,33,88. The post-order traversal of the tree above is 1,4,6,9,11,13,14,18,33,88. The in-order traversal of the tree above is 1,6,9,4,14,13,88,33,18,11
