+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.)
