Question

The procedure call mystery(38) will yield which output? __________ a) 0 12 b) 12 0 c) 1 1 0 2 d) 1 1 1 1 e) 2 0 1 1 public void mystery (int n) { if (n>2) mystery (n % 3); System.out.print( (n / 3) + " " ); }

Answer 1

Option b is the correct answer for the above question.

Step-by-step explanation:

• The mystery function is a recursive function that calls for the two times when the user passes 38 on the argument.
• The first value is 38 and the second value is 2 for which that function is called.
• When the value 38 is passed, then again 2 is passed because of the "mystery (n % 3);" statement.
• This statement holds by the if condition which gives the true when the argument value is greater than 2.
• Hence for the 2 value the if condition will not true and the function is not called again.
• Then the 38/3 and 2/3 are printed whose value is 12 0, but it will print 0 12 because of the recursive function.
• Hence option b is the correct answer while the other is not because other options does not states the output of this program.
