    float s=0,sum=0;

    float av;

    scanf("%d",&n);

    for(i=0;i<n;i++)

    {

      scanf("%d",&a[i]);

    }

    for(i=0;i<n;i++)

    {

      if(a[i]>0)

        sum=sum+a[i];

      else 

        if(a[i]<0)

          s=s+a[i];

    }

    av=(s+sum)/n;

    printf("Sum=%.0f",s);

    printf("\nSum=%.0f",sum);
