The current readings are 123 and 12345. Assuming that I do not reset the trip meter, when is the next time both readings will be palindromes?
When was the most recent time both readings were palindromes?
Prove no matter what the mileage and trip meters read, they can eventually be made to both be palindromes without resetting the trip meter.
Note: A palindrome reads the same forwards and backwards, like 262 or 37173.
