For this, you will need the ExpressionTreeNode and ExpressionTree classes, which you can get here: https://github.com/nextcs-dw/dwsource/tree/main/Expression
Reminder: Test Thursday 4/18
Modify your Expression tree to allow for the following capabilities:
- When an operator node is selected (via mouse press), it changes to another operation. Cycle through the operations like so:
+ - * / + ... - When a value node is selected, if it is non-zero, change it to zero. If it is zero, change it to an integer in the range [-99, 99]
