Expert Solution & Answer
Chapter 4, Problem 26E
Explanation of Solution
Justification:
- The key idea is to include an indication of scope (referencing environment) in each node of the tree.
- For a language with static scope, the symbol table might consist of a “scope tree” and a mapping from “(id, scope_num)” pairs to type and other information.
- Each “symtab” attribute in the AST would be a pointer to a node of the symbol table scope tree.
- A lookup “((name, t) ϵ symtab)” operation would walk the path from the current scope node to the root of the scope tree...

In this lab, we'll be practicing what we learned about GUIs, and Mouse events. 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.
"
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.

You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array.
