    {
        int b[11], n, i;
        while (~scanf("%d", &n))
        {
            i = 0;
            while(n)
            {
                b[i++] = n % 2;
                n /= 2;
            }
            i--;
            while(i >= 0)
                printf("%d", b[i--]);
            printf("
");
