[SOLVED] DataStructure -Project #2

Description

Introduction:

In this project you will modify the author’s BinarySearchTree code     to implement some new methods.

Description:

Modify the author’s BinarySearchTree code to implement the methods    shown below.

Each method is 10 points.

1. nodeCount

Recursively traverses the tree and returns the count of nodes.

1. isFull Returns true if the tree is full.  A full tree has every node            as either a leaf or a parent with two children.
2. compareStructure

Compares the structure of current tree to another tree and returns           true if they match.

For example, these two trees have the same structure:

5           10                   /          /

3   8       5   15

/          /                 1   4       2   7

1. equals

Compares the current tree to another tree and returns true           if they are identical.

1. copy

Creates and returns a new tree that is a copy of the original tree.     f) mirror

Creates and returns a new tree that is a mirror image of the original tree.         For example, for the tree on the left, the tree on the right is returned:

100                 100

/                  /

50   150    –>     150  50

/

40                           40

/          45                         45

1. isMirror Returns true if the tree is a mirror of the passed tree.
2. rotateRight

Performs a single rotation on the node having the passed value.         If a RotateRight on 100 is performed:

100                  50

/                   /

50   150    –>      40   100

/

40                      45    150

45

1. g) rotateLeft

As above but left rotation.

1. printLevels – performs a level-by-level printing of the tree.
2. main – demonstrate in your main method that all of your new methods work.
