Some hours earlier, many people started reporting that they could not see anyone's submissions nor their own submissions on problems. This seems to have been fixed and interactive problems have a new feature!

Among recent submissions for interactive problems I noticed a new feature that appears when opening the submission from the submissions page on a user's profile, which now shows for each testcase the actual interaction (Input and Output) between the judge and your solution. And a contrast with the model solution for the problem.

Testcase log Model solution log

Example from my submission 370197687 for 2133C - The Nether.

It seems as something messed up Codeforces submissions while they were implementing this new feedback feature. What do you think?

Do you ever get that feeling of inmense pride or just happiness after succesfully solving a problem you tought was really hard and actually tested your skills, motivating you to continue down this path of trying everyday to get a little better than the day before at Competitive Programming?

For example, today I got stumbled by this round's problem B. I didn't know how to approach it, until after brainstorming ideas, I settled on making the array divisible by $$$k+1$$$ using $$$k \equiv -1 \pmod{k+1}$$$. This single observation made my day and I want to keep making these kind of ideas in the future. So I keep doing problems everyday for the fun of it.

Or is it just me?
