               int n,sum=0;

               Scanner s=new Scanner(System.in);

               System.out.println("Enter the size of an aaray-:");

               n=nextInt[n];

              int a[]=new int[n];

             System.out.println("Enter all the element in array-:");

              for(int i=0; i<n; i++)

                  {

                       a[i]=s.nextInt();
