Write method levelOrder to perform a level-order traversal of a binary tree object. Modify the program of Fig. 22.16 to use this function.
The program of Fig. 22.16 illustrated three recursive methods of traversing a binary tree—inorder, preorder and postorder traversals. This exercise pre- sents the level-order traversal of a binary tree in which the node values are printed level by level, starting at the root node level. The nodes on each level are printed from left to right. The level-order traversal is not a recursive algorithm. It uses a Python built-in list object to control the output of the nodes. The algorithm is as follows: 1) Insert the root node in the list 2) While there are nodes left in the list, Get the next node in the list Print the node’s value If the reference to the left child of the node is not None Insert the left child node in the list If the reference to the right child of the node is not None Insert the right child node in the list.
