Here is the problem: 986C My submission got AC: My submission
But I found that my solution is totally wrong. Here is the hack data: 2 2 3 2 My output is 1. Obviously, the correct ans is 2. And I discoverd this data can hack my classmate's submission too.
What should I do? Can I add this data to Codeforces dataset?
Hm, there is no hack button showing up for me. I think maybe the contests that do not have validator cannot be hacked (because they cannot generate the correct answer)?
dude you can't hack it because the contest is old
why would that mean you can't hack it
Because, as said in the uphacking post, there is a 1 week phase after the contest when you can hack solutions. This contest is more than 1 week old so you can't hack solutions from it.
bruh moment
can I talk to Um_nik or Mike, and asks them to add this data?
Told Mike. I find 52C has some problems too. I told Mike and Mike modifyed the data.
You can write PM or mention me (like this [ user:GavinZheng ], but without spaces: GavinZheng). Your test is added, thanks.
:)
