Is the competition going to be on the Codeforce judge system or a separate system?
As an author, I am sure that you will enjoy the contest.
The contest is prepared by one of the greatest teachers for competitive programming Shayan and the first-ever LGM from Iran alireza_kaviani, so I don't think there is any doubt whether the contest will be great or not.
and also first ever IM from Pakistan (you).
As a participant, I think the opening contest of Repovive will be really interesting, especially seeing who the problem setters are!
Can you please add rust support?
There are three things you can watch forever: the usual ones and how Egor asks yet another online judge for rust.
Any update on another postponement and newly introduced Repovive Pre-Opening Contest? Asking because now the actual Repovive Opening Contest is clashing with M(IT)^2 2025 Winter Contest Advanced Division Individual Round which was planned to happen at that time long ago
Thanks for adding rust, but 1.40 is akin to c++ 98 – you can theoretically use it, but not really. Can you update to the last version, please?
We added Rust 1.92. Thanks for the suggestion
Thanks, this is much better. For some reason it is 1.75 now. But even for that please add --edition=2024 (if you update to at least 1.85, otherwise --edition=2021) to command line arguments.
And one other thing — currently I can see that I've got a compilation error, but not a compiler message
We'll work on both to resolve them for the next round!
Can C++17 be supported?
Also, is there a way to view others' in-contest submissions?
Different versions of C++ are available now. And it's now possible to view others' submissions after the contests. Thanks for your suggestions
Please introduce a ban feature. I saw someone in the recent contest who solved problems D and E within a 2-minute difference. Won't hesitate tagging him: arnabmanna, and his alt Destroyer0069
Both are banned alts of the same person.
An old blog about him: https://codeforces.me/blog/entry/144254
When will the editorial for the Repovive Pre-Opening contest get published?
It's already published and available here.
Got it. Thank you! :)
Is the contest delayed?
add UPD 3 because contest is on Dec 14, 2025, 7:35 PM GMT+05:00
If the contest is delayed, you should add upd 3.
The hyperlink is displays Dec 7th instead of Dec 14th
what the heck is this internal error??? (I got 4 on prob A)
same, is there a problem with the judge?
seems like a trash backend
the leaderboard hasn't updated until now
i tried submitting a few times, one attempt it seemed like it was running but failed
nvm, the submissions will be automatically rejudged
There is a lot of traffic
Same here, on both A and B
announcement just out work on the other stuff the traffic is too much
Mine get to a running state after removing pragmas
UPD: And then internal error again :/
It means the error has been rescheduled.
When can we expect the winners to be announced?
problem "D" accepted in o(n). please anyone tell me it's hackable or not ~ int main(){ ll t; cin >> t; while(t--){ ll n; cin >> n; ll len = n; n*=2;
string s; cin >> s; ll cnt1 = 1, cnt2 = 0; ll mx = 0; vector<ll> a(n),b(n); for(ll i=0;i<n;i++){ if(s[i]=='(')a[i]=1; else a[i] = 2; } b[0] = 1; for(ll i=1;i<n;i++){ if(cnt1==len){ b[i] = 2; }else if(a[i]==1 && cnt2<cnt1){ b[i]=2; cnt2++; }else if(a[i]==2 && cnt2<cnt1){ b[i] = 1; cnt1++; }else{ if(cnt2>=cnt1){ cnt1++; b[i]=1; }else{ b[i]=2; cnt2++; }}} for(ll i=0;i<n;i++){ if(a[i]!=b[i])mx++; } cout << mx << endl;}}~
