Consider the following method.
public static int calcMethod(int num)
{
if (num == 0)
{
return 10;
}
return num + calcMethod(num / 2);
}
What value is returned by the method call calcMethod(16) ?
A
10
B
26
C
31
D
38
E
41
E

Consider the following two static methods, where f2 is intended to be the iterative version of f1.
public static int f1(int n)
{
if (n < 0)
{
return 0;
}
else
{
return (f1(n - 1) + n * 10);
}
}
public static int f2(int n)
{
int answer = 0;
while (n > 0)
{
answer = answer + n * 10;
n--;
}
return answer;
}
The method f2 will always produce the same results as f1 under which of the following conditions?
I. n < 0
II. n = 0
III. n > 0
A I only
B II only
C III only
D II and III only
E I, II, and III
