Double-base palindromes
|
||||||
|
Problem 36
|
||||||
|
The decimal number, 585 = 10010010012 (binary), is palindromic in both bases.
|
||||||
|
|
||||||
|
Find the sum of all numbers, less than one million, which are palindromic in base 10 and base 2.
|
||||||
|
|
||||||
|
(Please note that the palindromic number, in either base, may not include leading zeros.)
