      if(x<=1)  return (1);

      t=sum(x-3)+sum(x-1);

      return (t);

    }

    if 6 is passed to the function, what is the value returned to the  calling function.

     (((((((ANS=====   9)))))))))

          {int I=100;

            I--;

            Printf(?%d?, I);

            }

    }

    find output.
