                int n=input.nextInt();
                for (int i = 1; i <= n; i++) {
                        if (i % 2 == 0) {
                                sumevenNo += i;
                        } else {
                                sumoddNo += i;
                        }
                }
                System.out.println("Sum of even numbers: "+sumevenNo);
                System.out.println("Sum of odd numbers: "+sumoddNo);
