Need Help on Problem in Korean Online Judge

Revision en1, by woookje, 2019-04-02 10:31:10

While I was solving problem, I have encountered this problem: https://www.acmicpc.net/problem/17111

(Description is written in English, so you can see it.)

How can I solve this problem? I do not have any idea of solving it, and thought that Codeforces community is helpful.
