6. Consider the following recursive function: int mystery
(int number) //line 1 { If (number == 0) //line 2 return
number; //line 3 else //line 4 return (mystery(number + 1)
number; //line 5 }
a. Identify the base case
b. Identify the general case
c. What valid values can be passed as parameters to the
function mystery?
d. If mystery(0) is a valid call, what is the value? If not,
explain why.
e. If mystery(10) is a valid call, what is its value? If not,
explain why.
f. If mystery(-3) is a valid call, what is its value? If not,
explain why.

Solution
Given that,
Int mystery(int number)
{
if(number==0)
return number;
else
return mystery(number+1)-number;
}
The base case for this function is,
if number=0 then it returns 0.
The general case for this function is,
if number !=0 then it returns [mystery(number+1)-number].
The function mystery(10) is not valid,eventhough it is
passing valid int value.
The reason for this is here the function checks for the
number value,whether it is equal to 0 or not,if not equals to
0 then it again calls the function with addion value and
subtracting the number from that.
