The point values will be 100-300-400-550-600-625-625-650.
Since this contest is used as a qualification round for a local onsite contest, the problems are a bit different from usual ABCs. The style of the problems is a bit closer to ARCs, and the problems are a bit harder. Please refer to previous contests prepared in a similar manner.

We are looking forward to your participation!
Never seen point values being so odd.
The subject of the contest is very difficult, I think.
Yes. I've been crushed by D. :(
The problems are "a bit" harder.
Update: Only solved ABCDE during the contest. It's really difficult!
No god please no
I only solved AB
My rating will go down rapidly
G : https://atcoder.jp/contests/abc313/submissions/44302729 O(maxA) pass
Sorry to inform that C == this. btw i got my penalty cuz my sol doesn't have enough array size...
I only solved ABC My rating will go down rapidly
Me too
Today's difficulty level of the problems I could solve According to me A < B < C < E < D
D was the most thinking I had to do among them, rest were pretty straightforward.
Is there any way to check a specific test case at Atcoder?
My submission for problem D fails at 1 test case out of the 29 test cases, and I'm not able to pinpoint where the error could be.
happened to me too, i was able to find a counter tho
n = 6, k = 3, a = [1, 0, 1, 1, 0, 1]
Might work for you
Nah, unfortunately, even this tc works for my code.
bro did u use gauss elimination?
i know why i got wa*1 now, cuz this testcase will lead to multiple solutions.
no i didn't
awa
I think problem D is very fantastic. May I ask the atcoder_official team, how do you come up with this problem and idea? Is there any related problem or similar idea that inspires you? I think to create such a problem is even harder than solving it.
I have passed all the ABCDE questions. Do any talented programmers tell me how to write F questions？
