CMSC Data Structures and Algorithms
Programming Project
The third programming project involves writing a program to read in the preorder representation
of a binary tree and determine whether it is a balanced binary search tree. Given the binary tree
shown below:
Its preorder representation would be The
asterisks represent null children.
The program should repeatedly prompt the user for a binary tree. It should then display the tree
using indentation. For the above tree, its indented representation would be as follows:
It should then categorize the binary tree in one of three ways:
It is not a binary search tree
It is a balanced binary search tree
It is a binary search tree but it is not balanced
If the tree is not a balanced binary search tree, a binary search tree containing the same set of
values should be constructed and displayed in the indented format shown above. It is not
expected that the existing tree be rebalanced, just that a new tree with the same set of values be
constructed. Then the height of the original tree and the balanced binary search tree should be
displayed.
Shown below is a sample session that involves each of the above cases:
