Clarification Needed on Dataset Alignment between submission_all and problem

[grandsmile]

I’m working with the TestCase-Eval datasets (submission_all and problem) and need clarification on how to correctly map submissions to their corresponding problems.

Currently, the problem_id in submission_all (e.g., "2031A") does not appear to align with the actual problem in problem (e.g., Codeforces problem 2031A). For example, a "right submission" labeled with problem_id=2031A is clearly not a solution to the Codeforces problem 2031A（https://codeforces.com/problemset/problem/2031/A).

Could you please clarify:

What is the correct way to map submissions in submission_all to problems in problem?
I would like to obtain both correct and incorrect solutions along with their corresponding problem descriptions.

Thank you for your assistance. Looking forward to your guidance.

Hi,

Thank you for your question.

I have manually checked all the "right submissions" with problem_id "2031A" in the submission_all dataset. For each entry, I replaced the ID in the following URL format:
https://codeforces.com/contest/2031/submission/{id}
For example, the first entry is this submission.

From my checks, the code content is consistent with what is shown on the original Codeforces website for problem 2031A. Please note that you need to be logged in to Codeforces to view the submission details.

Could you please point out a specific submission where the problem_id does not match the actual Codeforces problem? I will be happy to investigate further.
