In Test Case 1, we executed the program statements on lines 1-5 out of 12 lines of code. As
a result, we had 42% (5/12) statement coverage from Test Case 1. We can attain 100%
statement coverage by one additional test case, Test Case 2: the method call foo(1, 1, 1, 1,
1.), expected return value of 1. With this method call, we have achieved 100% statement
coverage because we have now executed the program statements on lines 6-12
