Can somebody please explain how to solve this problem?

Editorial is horrible and it's impossible to understand how it's solved.

Thanks.

Original problem — https://atcoder.jp/contests/agc005/tasks/agc005_d
Editorial is horrible because I really doubt the author knows how to solve it.
Author copied his submission from https://atcoder.jp/contests/agc005/submissions/15299098

Lines written in the name of the editorial (on hackerearth) are just randomly picked from atcoder editorial https://img.atcoder.jp/data/agc/005/editorial.pdf which doesn't make any sense.

Thanks Kuroni for linking original source to me.

Upd: Even testcases are copied from atcoder. Atcoder testcases available on dropbox

    Sounds like hackerearth is paying for copying problems

    The author of this problem too has written a wrong editorial.Poor test cases and now wrong solution in Editorials.Hackerearth is degrading day by day.

    Wow, the Author just copied an AtCoder Grand Contest's Problem-D, for a question in August Easy 2020. Another level of relativity! :(

    Only solved by 40 people, in AGC. Author, first of all, you shouldn't have copied. Other point, you copied a problem which can be marked as "hard", in an "easy" challenge of Hackerearth. Just WOW! (Did you even think once before doing that?)

    Arpa please look into this issue, as soon as possible!

Sure contest admin don't care about the quality. He just wants to steal money from HE. Call gray guys for tasks, greedy take testing and careless. Ignore responsibility, didn't fix statement/solution for mistake.

All the copying and stuff is unfortunate. But, can someone please provide an English explanation?
