Project Euler Problem 036

# Statement

The decimal number, $585 = 1001001001_2$ (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

This solution is quite straight-forward just notice the detail that I compare just non numbers.

This is because no even number will be palindromic in their binary representation due to the

fact that they end in 0 and there is no 0 in the beginning.

from CommonFunctions import is_palindrome if __name__ == '__main__': result = sum(x for x in range(1, 1000000, 2) if is_palindrome(x) and is_palindrome(bin(x)[2:])) print("The result is:", result)
