SOE has a grading tool Grade_Assign that implements GradeIF interface with a defined assigning() method. Recently, SE has a GPA_Compute tool developed, and CE has a Credit_Calculate tool developed. These two tools have methods computing() and calculating(), respectively. The SOE would like to have an integrated grading tool named SOE_Tool. This tool builds on top of the Grade_Assign tool and the assigning() method can assign grades but also compute GPAs and calculate credits. Since the original three tools were used in different departments, you are asked not to modify the existing code. Show the UML class diagram for your design for the SOE_Tool. Decorator show code for soe_tool in c#.
