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?
