User named "shree_e" has copied my code for Problem A and submitted it during the ongoing contest (Codeforces Round #696 (Div 2)) after I locked my submission. But as far as I know no one should be able to see my code until they've made a successful submission during the contest. But this guy @shree_e was able to copy my code without a successful submission from his side. I have not used ant online platform to edit and test my code. Today, I received a mail from codeforces warning me of copying code (or distributing my code).........but that isn't the case. For proof, I have attached screenshots regarding the submission details of me (Sugar_539) and that of shree_e's.
My(Sugar_539) — 104788438 (time submitted : 20:28)
shree_e — 104803384 (time submitted : 20:51)
Based on the time, Codeforces system has skipped the submissions of shree_e, but also I was given a strike, which is unfair. I hope the Codeforces community is with me on this!
There is actually a way that this happens , a person who submits can then give code to others who haven't yet submitted . And it's so unfortunate that this happened to you. I think this feature can cause real troubles with the rising amount of unethical practices . I would request everyone to suggest ways to deal with it.
Ok, are you suggesting that I gave him my code (from outside) ? No way, I don't even know that person (@shree_e). (Also, there's no way for me to prove my point here!)
No, actually someone other who has also solved it and locked it can always see your solution and give it to someone.
OMG! I had no idea such things happen. So is it better to not lock our solutions?
If you're likely to make hacks, then lock it. If you normally don't hack, then don't lock it.
Usually I don't hack, so I think it's better not to lock!
No , i meant someone else locked his submission and then shared your code to the user you are talking about.
Yeah sorry I understood it now !
In my opinion on contest hacking should be stopped. This is helping people to cheat easily.
I have just written a blog on it. people lock their code and view others code and make them public.
Maybe allowing hacking phase only after the contest can be a solution to tackle these issues.
Yeah this has to be done!
