Decimal and Binary Palindromes

A number/string is a palindrome if the digits/characters are the same when read both forward and backward. Examples include "racecar" and 12321. Given a positive number n, check if n or the binary representation of n is palindromic. Return the following:

• "Decimal only." if only n is a palindrome.
• "Binary only." if only the binary representation of n is a palindrome.
• "Decimal and binary." if both are palindromes.
• "Neither!" if neither are palindromes.

Examples

palindrome_type(1306031) ➞ "Decimal only."
# decimal = 1306031
# binary  = "100111110110110101111"

palindrome_type(427787) ➞ "Binary only."
# decimal = 427787
# binary  = "1101000011100001011"

palindrome_type(313) ➞ "Decimal and binary."
# decimal = 313
# binary  = 100111001

palindrome_type(934) ➞ "Neither!"
# decimal = 934
# binary  = "1110100110"
