Expert Solution & Answer
Chapter 17.2, Problem 8SC
Explanation of Solution
Tree:
- A data structure that is present in the hierarchical form and is composed of nodes.
- Each of the node will be having a sequence of child nodes and also one of the node is considered to be a root node.
Huffman Tree:
In a Huffman tree the leaves will have the symbol that needs to be encoded. In order to encode a symbol walk along the path from the root node to the leaf containing the symbol and it produces zero for every left turn and one for every right turn...

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels.
