              if(n >0)

         {

               i++;

               fun1(n-1);

          }

          Return(i);

          }

           Fun2 (int n)

           {

                      Static int i = 0;

                       If(n > 0)

           {

                      i = I + fun1(n);

                      fun2(n-1)

            }

            Return I;

           }
