MP1: Debug Me

The Assignment

This graded assignment consists of three short programs:

• Factorial
• Winner
• QuizMaster

Each program contains bugs, is incomplete and requires further work. Each programming problem includes a test program. Each program is tested using different input values and its output is checked against the required output. If there is a discrepancy in your program's output, the Console window will include more details about which lines were correct and which were incorrect. Your challenge is to modify Factorial.java, Winner.java, and finally QuizMaster.java, so that all of the unit tests pass. The grade for MP1 is based on the fraction of unit tests that succeed.
