In this Codeforces problem "Jeff and Digits", Jeff has n cards, each marked with either a 0 or a 5.
He wants to arrange some of them to form the largest possible number that is divisible by 90.

A number is divisible by 90 if and only if:

It contains at least one 0 (for divisibility by 10).

The sum of its digits is divisible by 9.

Your task? Figure out how Jeff can use his cards to form such a number—or determine if it’s impossible!
