I have this code:public class RecurLoopTest {    public static void main(String[] args) {     printit(2);        }    private static int printit(int n){        if(n>0){            printit(--n);        }      System.out.print(n+,);      return n;   }}I have drawn a execution flow/memory flow diagram for above program.  Is this diagram correct or do I need some changes to make it correct?What I have drawn looks like this:Link to edit diagramLink to view diagram
Execution flow diagram of loop test

It would be better to add the method arguments in the diagram, for example:printit(0) -- n=0, prints 0,, returns 0printit(1) -- n=1, prints 0,, returns 0printit(2) -- n=2, prints 1,, returns 1main()I don't think you need 4 drawings side by side for this, just one like this would be clear enough already.
