While checking out other people's submissions (too see what the simplest/shortest way to implement a problem is), I noticed that many of the last 10 submissions were... exactly the same. It's all just copy-pasted from one person.
https://codeforces.com/contest/1569/status/E
My question is, why would anybody do this? The contest is over. And by copy-pasting another person's solution and submitting it, you learn exactly nothing. Isn't it just a waste of time?
Can anybody explain this to me, am I missing something obvious? I can't think of any reason why anybody would do this.
A possible take to your question. You want to keep your daily streak by answering problems but you need to fully solve them only will they be counted as solved problems and only will your streak increase.
I didn't know there was a daily streak feature on CF, thx
Funnily enough, Github took their streaks away because it promoted unhealthy coding habits or something. But there are extensions to get it back. (It was easy to fake anyway)
i wanna share my experience regarding this , i submitted editorial code on cses dp section once . I did this because my approach was exactly same as mentioned in editorial but still i was getting TLE , hence i decided to upload editorial code to check whether is this question really accepting solutions or just giving TLE on all submissions . I later compared my code with the editorials code and found my inner loop is outer loop of editorial's code and vice versa .. when i exchanged the loops i also got AC , today also i dont know what was the issue in my code ;( Later i found in comments its happened with some other guys too but still i am not clear what that ques really demanded ;(

That's most likely the reason, it was probably a 2D or 3D dp right? Google "cache locality" or "cache hits" or "cache memory" or something like that to find more.
yeah it was a 2D dp .. thnx for sharing these links , will surely go through them and try to gain a general understanding of cache.
One possible reason could be someone found a problem uninteresting and dont want to ever waste time on it.
Then why don't they just don't submit any solution at all ?
Then how will you know that earlier you tried it and didnt like.
Submit an empty solution to color it in red
By reading the problem and not liking it again.
It's annoying to me when Kotlin rounds show up in the problemset, so I just fakesolved some of the Kotlin problems that way I don't see them on the problemset.
You can make a mashup out of those problems and solve them in your desired language.
Great idea!
