RMI_2019, day1 Restore problem, no editorial = no understanding

Revision ru1, by Nurss, 2023-03-16 18:05:47

I have been trying to solve Day1 C problem and there is no editorial(at least I didnt find it). I've tried understanding codes, but I have no idea. If somebody did solve it could you explain your idea?
