Hey guys!

This year, I decided to start posting different videos other than some codeforces editorial videos, and so I decided to make video editorials on easier IOI problems!

You can check out the first video on IOI 2018 Combo I posted on my channel:

As always, please let me know what you think, so that I can improve my content, and please let me know if there is a specific problem you would like me to do a video on. Thank you!

UPD: I posted another video, this time the question is IOI 2022 Insects, which was the first (and only) problem I solved at the IOI! I'm splitting this one into three videos, so here is the link to the first part: video

Hey guys,

I have realized that most codeforces guides include something like doing more problems, or some strategy to help people practice. Instead of making a video like this, I have decided to make a new video series where I share some tips and tricks I have come across while solving the easier problems (Div. 2 ABC) in some unorthodox ways. This will include things like how to quickly guess and prove a solution, using sample cases to your advantage and learning some common ideas in these questions.

I have uploaded my first video in which I go over two questions, which are relatively tricky to find out where to start, but become much easier when you notice a pattern in the sample cases.

Please let me know what you think of it and if you have any suggestions please tell me so I can improve my videos in the future. Thank you!

Hey guys, about a month ago I made a YouTube channel, where I post video animated editorials to some questions I have solved in-contest that were cool or interesting to me. The problems I have made editorial videos on are:

1787C - Remove the Bracket (today's contest problem C)

video

1775D - Friendly Spiders

video

1782D - Many Perfect Squares

video

1775A2 - Gardener and the Capybaras (hard version)

video

1783D - Different Arrays

video

1768D - Lucky Permutation

video

1779A - Hall of Fame

video

Please tell me what you think of them and let me know if you have any suggestions so I can improve my videos. Thank you so much!!

Hey guys,

Whats the most unique or coolest problem statement for a competitive programming problem you've seen? Doesn't have to just be from codeforces.
