              int n = sc.nextInt();

              int i ;

              int r = 1;                                                 // used to change the sign

             int s= 0;                                               // variable for sum

                  for ( i=1 ; i<= n; i++)                          // for loop iteration

                   {

                           s= s + r( i/(i+1)) ;                      // execution of sum

                          r = -1( r);                                  // sign of next term is changed

                  }

                System.out.println( " sum of series = " + s);    // display sum

            }
