This is the list of teams going to Amritapuri Regionals. You can update handles of your team in this sheet . The table only contains teams who filled the handles in above sheet. I will be udpating the tables every 12 hours or so.

$$$\textbf{I'm stopping updating the tables because someone keeps on messing up with the sheet, and it takes too much effort to undo all the changes.}$$$

I prepared a tutorial on Mobius Inversion and multiplicative functions, with some problems.

I tried to make it as such that it doesn't need any prerequisite about the mathematics involved behind it.

Link : Video

Slides

Slides are also attached in description if you prefer reading through text, than watching a video.

Since, this is my first video, ignore the mumbling and any constructive criticism are welcome.

I'm unable to solve even the easiest of Greedy problems... Maybe, because I don't feel convinced until I prove my solution, but that's hard sometimes even for easy greedy problems.

Anyone who faced this problem earlier, and found a way out?

Any suggestions regarding how should I practice greedy problems, or what problems should I practice will be of much help :-)
