Mobius Inversion and Multiplicative functions : Tutorial

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 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.

PS : I shared this on codeforces yesterday, but since most of Indian community is not on codeforces, so I am sharing this here too :slight_smile:


After long time seeing tutorial…thank you for your effort


Very very nicely written, thanks so much.
