What is the smallest and biggest palindromic number?
Since a palindrome is just a number that reads the same way back
and forth, the smallest palindrome would be 1. As there are an
infinite number of palindromes (as you could just take any
palindrome and simply place the same number in front of it and
behind it, for example: 3, 939,99399,9993999,999939999, etc.),
there is no biggest palindrome (infinity)
