Your task is to write a set of JUnit test cases that comprehensively test the

given code. A comprehensive set of test cases is one that not only checks if

the expected output is the same as the actual output, as described in the

specification above but also traverses all paths in the code. If there is a

conditional statement, both the true and false conditions should be tested.

For multiple conditions, all possible combinations of the conditions being true

or false should be tested. This means if the condition is "A AND B$,"$ four

different test cases should be written, unless it is not possible. The four

conditions are: A$=$True, B$=$True $$ A$=$True, B$=$False $-$ A$=$False, B$=$True $$

A$=$False, B$=$False.
