## Description
|
||
|
|
<section id='description'>
|
||
|
|
El número decimal, 585 = 10010010012 (binario), es palindrómico en ambas bases.
|
||
|
|
Encuentre la suma de todos los números, menos que n, mientras que 1000 <= n <= 1000000, que son palíndromos en la base 10 y en la base 2.
|
||
|
|
(Tenga en cuenta que el número palindrómico, en cualquiera de las bases, puede no incluir ceros a la izquierda. )
