Ugly mathjax in codeforces with macOS + chrome
By xzm2024, history, 2 years ago, In English

Hi, I find the mathematical formulas are ugly when I use macOS + chrome.

For example, 1768A - Greatest Convex, when I use macOS + chrome, it shows ugly

But when I use macOS + safari, it shows normally

And I find it is normal when I use polygon, for example, 104025A - Gifts in box

macOS+chrome in polygon: normal

macOS+chrome in gym: ugly

macOS + safari in gym: normal (You can see the difference of $$$1 \times 1 \times 1$$$ and $$$h$$$)

I wonder know it is codeforces' bug or chrome's bug? Thank you~ Is there anyone else in the same situation as me?

When will interactor return exit code -1073741819?
By xzm2024, 6 years ago, In English

I wanna add a problem in polygon and it seems fine in tests and invocations. But when I wanna create package, it says PackageException: Failed on verification of the first test: Interactor 'interactor.cpp' returns exit code -1073741819. I try to fix it but failed. What problem may I have?

UPD: Thank MikeMirzayanov for help. He improved diagnostic messages so that I can know where I have problem.

A question about gym contest
By xzm2024, 7 years ago, In English

When I find there is something wrong in a problem, I need to rejudge all the submissions.

The question is how to rejudge all submissions quickly rather than opening each of then and click "rejudge"?
