Submit a positive integer nn less than 10510^5. Let the sum of the valid submissions from all teams to this question be SS. If you submit an invalid answer, you will receive 00 points. Otherwise, your score will be max⁡(0,⌊25−∣S′−n∣10⌋) \max \left(0,\lfloor 25 - \frac{|S'-n|}{10} \rfloor \right) , where S′S' is the sum of the squares of the digits of SS.
