    int m, n, sum;
    scanf("%d%d",&m,&n);
    while ( m > 0 && n > 0 ) 
    {
        sum = 0;
        if ( m > n ) swap(m, n);
        for ( int i = m; i <= n; i ++ ) 
        {
            printf("%d ",i);
            sum += i;
        }
        printf("Sum=%d\n",sum);
        scanf("%d%d",&m,&n);
    }
    return 0;
