Question

public class Program
{
public void fnRec(int p,int q){
if(p>q)
{
return;
}
System.out.print("\n ---"+p);
fnRec(p+1,q);
System.out.print("\n +++"+p);}
public static void main(String[] args) {
Program ob=new Program ();
ob.fnRec(5,9);
}
}
output =
---5
---6
---7
---8

Answer 1

fnRec function doesn't subtract anything it's just outputting '+++' part reverse because that statement is after the recursive method fnRec
