Question

Look at the following method: public static int test2(int x, int y)
{
If ( x < y)
{
Return -5;
}
Else
{
Return (test2(x - y, y + 5) + 6);
}
}
What is returned for test2(18,5)?
A) 6
B) -5
C) 7
D) 1

Quizplus · Accepted Answer

When test2(18,5) is called, x is greater than y so the else block is executed. test2(18-5,5+5) + 6 is returned which reduces to test2(13,10) + 6. Since 13 is still greater than 10, the else block is executed again and test2(3,15) + 6 is returned. This continues until the values become negative. Finally, when test2(-2,30) is called, x is less than y so -5 is returned. This result is then added to 6 that was being carried in the function call stack from the previous returns, resulting in 1. Therefore, the correct answer is C.
