A ternary tree is like a binary tree, except each node in a ternary tree may have three children: a left child, a middle child, and a right child. Write an analogue of the TreeNode declaration that can be used to represent the nodes of a ternary tree.
The three common types of traversal with a binary tree are __________, __________, and __________.
Propose a definition of a preorder traversal for ternary trees, and give pseudocode for accomplishing such a traversal.
Give an algorithm for a function void increment (TreeNode *tree) that increments the value in every node of a binary tree by one.
Imagine a tree in which each node can have up to a hundred children. Write an analog of the Tree Node declaration that can be used to represent the nodes of such a tree. A declaration such as TreeNode \\{int value; TreeNode \(*\) child 1 TreeNode \(*\) child 2 TreeNode \(*\) child 3 };
