Hello guys! I hope you're having a good day.

Me, CoderAnshu, XORring-Samurai and obliviousz from Competitive Programming Group, COPS IIT-BHU attempted to make a video editorial for problems A to E of the Educational Codeforces Round 103.

Here's the link for the complete playlist: https://www.youtube.com/playlist?list=PLLt4yMoVgczWm1VzN3O4y29VElipDNJ1H

Subscribe to the Youtube channel to stay tuned for the upcoming video editorials. We also have a curated list of topic-wise concept videos, you can check that out in the Playlist section.

Happy Coding!

PS: CoderAnshu was the first one to solve E, and in just 6 minutes.

Dark Reader + Codeforces Christmas Theme sucks.

So, I tweaked the Theme file to make it work well, and here are the results:

[WITHOUT FIX] PROBLEMS
[FIXED] PROBLEMS

[WITHOUT FIX] BLOGS
[FIXED] BLOGS

To get the same dark theme:

1. First download the Dark Reader extenstion for your browser (Skip if already installed).
2. Visit this website.
3. Click on RAW and copy the code.
4. Open the Dark Reader extension and click on the Dark option.
5. Click on the Dev Tools option at the bottom, and replace the text in the text area with the copied code.
6. Click APPLY and you're done.

Edit:

If you want to remove that snowflakes image too, then copy and paste the code from this website instead.

Enjoy the real dark mode!

In short: If a problem has 4 sample test cases, and code fails at test 4 then wrong submission is counted, but if it fails at test 1, this code is not counted as wrong submission.

We often over-read the sample output and submit the code, which costs us points. I suggest, if any of the sample test cases fail, wrong submission shouldn't be counted.

MikeMirzayanov, Please look into it.
