Find the palindrome numbers (two or more digits) from 1 to n where n is the number passed to the function.
Problem asks for palindromes starting at 1, but test cases start at 100.
Now it goes down to 10, but wouldn't single digits be considered palindromes as well?
Additional test cases were added and the description slightly enhanced.
