Recursive Tracing. For each call to the following method, indicate what value is returned: public static int mystery(int n) { if (n < 0) { return -mystery(-n); } else if (n == 0) { return 0; } else { return mystery(n / 10) * 10 + 9 - (n % 10); } Call Value Returned mystery(0) mystery(5) mystery(13) mystery(297) mystery(-3456) } Can any one help me with it?
