Adding up the digits and the digits reversed Given a number > 0, output the sum with all digits (1 .. n) concatenated and reversed and add them up. For example, with n = 6:

The numbers 1 to 6 concatenated:

123456


Reversed:

654321


Adding them up together will result in: 777777. Another example is n = 11:

1 2 3 4 5 6 7 8 9 10 11 &gt; 1234567891011


and

11 10 9 8 7 6 5 4 3 2 1 &gt; 1110987654321


Adding them up together will result in 2345555545332. This is also known as A078262.

L        range from 1 .. input
 D       duplicate
