Consider the following code examples, where all variables are of type int:

Example 1

x = n;

y = x;

while (x > 0) {

y += 1; x /= 2;

}

Example 2

x = n;

y = x;

if (x > 0) {

while (x > 1) {

y += 1; x /= 2;

}

}

Assume that the two examples start with the same value for variable n. For which value(s) of n do the two code examples compute the same value for variable y?

I. Any value less than zero

II. The value zero

III. Any value greater than zero

1) I only

2) II only

3) III only

4) I and II only

5) I, II, and III
