In a ternary tree, each node has at most three children, referred to as the left,
middle and right child of the node.
The sorting rules for a sorted ternary tree are as follows:
All the elements in the left subtree of a node are smaller than the element in
the node.
All the elements in the right subtree of a node are larger than the element in
the node.
All the elements in the middle subtree of a node are equal to the element in the
node.
Inorder traversal of the tree is defined recursively as follows:
traverse the left subtree, the root, the middle subtree, and the right subtree.
Write a program that reads a list of nonnegative integers ending with a 1 and
stores them in a sorted ternary tree. A new element should always be connected
to a leaf.
Print the tree inorder after every element is inserted.
For example, for the input:
3 10 5 5 2 17 12 8 1 3 5 1
The program should build the following tree:
The program should print:
3
3 10
