Just out of curiousity.

So as I have noticed,Codeforces will be holding three competitions at the same time about 25 hrs later.(ICPC Challenge powered by Huawei,Kotlin Heroes and upcoming div.4)

So far,the judging system have already shown signs of significant lag.I've been suffering from 5 minute pending queue for quite a while.

Now,since the div.4 is the most participated round in codeforces,that will certainly bring more lag and longer queue to the server.So I now wonder whether the admins have some backup plans about this judging surge or just extend the round to digest the long queue.

Run id 224039373 status:CE

after noticing the CE error I found I've been using the wrong language to submit,then I tried GNU C++17 and it worked.

but the CE record is just weird,it reported an issue finding the header,but the only header I was using in the program was iostream and algorithm.

before that was a TLE record Run id 224039721,it has the iostream,algorithm and map header,but it managed to be compiled then stuck on time limit,lol.

The main problem is that CE promblem which makes me confused.but it'll be appreciated if someone can explain the TLE thing,is it a bug or a feature?
