A program has three inputs $A,B$ and $C$ with the ranges $1,30$

$15,39$ and

$[50$ and $200]$ respectively. The program performs the function $C-(5^{**}(B)+C)$

and outputs negative $($if the result is negative$)$ or positive $($if the result is

positive$).$ Find all the test cases and respective expected outcomes for BVC

and robust testing. Also find the number of test cases for worst$-$case testing.
