what output is produced by the following program? Before running the code, you should trace the code and write down the expected output. Tracing the code by hand will be a helpful skill as your debug code and examine the logic of a program.

public class MysteryReturnPreLab { public static void main(String[] args) { int x = 1; int y = 2; int z = 3; z = mystery(x, z, y); System.out.println(x + " " + y + " " + z); // Statement 1 x = mystery(z, z, x); System.out.println(x + " " + y + " " + z); // Statement 2 y = mystery(y, y, z); System.out.println(x + " " + y + " " + z); // Statement 3 } public static int mystery(int z, int x, int y) { z++; y = x + 1; x = 2 * y - z; return x; } }
