The decimal number, 585 = 1001001001 (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.)
|
||
|
|
|
||
|
|
solution: We can skip all even numbers since a even number would end in binary 10 - In reverse that would be 01 and we are told to skip leading 0's
