How long does it take to get a palindrome answer?
You will nearly always arrive at a palindrome answer within six steps. Try one of these numbers 68 or 79. If you choose a number greater than 89 arriving at the palindrome answer takes more steps but it still works. But don’t try 196! In fact, avoid it like the plague….
