May I ask, what is a palindromic number?
A palindromic number is one which when read both ways is the same.
Example, 23432 is a palindromic number since whichever way you read it from front or back results in 23432, Neo.

i thoguht you meant to form a whole new palindrome.. then i got 1 mile
No Julia, it's the total odometer reading that should form a palindrome not the distance travelled from the present reading.
how many pallindromes are there between 1 and 100000?
a lot
