Assume that data is stored in a binary tree, but that unlike in the case of binary search tree, no attempt is made to maintain any sort of order in the data stored. Give an algorithm for a function search that searches a binary tree for a particular value num and returns true or false according to whether the value num is found in the tree.
A node with no children is called a(n) __________.
The three common types of traversal with a binary tree are __________, __________, and __________.
Give an algorithm for a function int smallest (TreeNode *tree) that takes a pointer to a root of a binary search tree as parameter and returns the smallest value stored in the tree.
