Could you help me with tracing this code below? I don't understand the part especially with xMethod(x-2); and xMethod(n-1); what they are doing in the code.

If you could explain with the visual description, it would be helpful.

3. What is the output of the following code?

public class Q3 { public static void main (String [] args ){ xMethod(4); } public static void xMethod(int n) { if (n > 0){ System.out.print (n + " "); xMethod(n-2); xMethod(n - 1); }

} }

output

4 2 1 3 1 2 1
