Question

Consider the following program. Assume that $x$ and $y$ are integers.

f(x, y)
{
    if (y != 0)
        return (x * f(x,y-1));
    else
        return 1;
}

What is $f(6,3)?$

• A. $243$
• B. $729$
• C. $125$
• D. $216$

Answer 1

Solution: (D) is correct. This code computes $x^y$. f(6,3) will compute $6^3$ which is 216.

Answer 2

 The given code computes the value of $6^3 =216$.

So Option $(D)$ is correct.
