Hello guys!

I was solving some problems on dp on subsets and I found this strange one

this got AC, but that gets TLE, and the only difference between them is swaping the inner 2 loops (mask and j).

I'm really curious to know why :D

Update: All is done. Thanks sir MikeMirzayanov.I really appreciate your great efforts.

A few years ago, div2 C difficulty was around 1600 — 1800, recently, it has been around 1200 — 1400.

Is it because of the great progress in people's levels? of course not.

The main reason is the cheaters.

I admit that their cheating doesn't affect me or some others, but what about beginners?

I found too many cheaters in the last edu round (also C) with a 100% identical submissions, I waited for them to be skipped but nothing happened! This the main reason I'm writing this blog. So, MikeMirzayanov please do something.

Below are some samples of identical submissions for div2 C -> last round

I know this blog will be downvoted by cheaters, but I don't care.
