Recently i was trying to learn mobius inversion but couldnot find anything in yt (i usually learn from vdos). But i came across a vdo and i pretty much know that he was/is a grandmaster on codeforces. But since i am not from india i am not able to access this free vdo. Can someone out there help me to get this? It will be of great help. I have seen many of his yt vdo to learn things and thats why i am asking for it. Thanks in advance. This is the vdo link: Vdo link

So... that video was just uhh, promotion of his Unacademy course, where he would actually teach the Mobius inversion, and I believe it's paid. So, were you asking for the youtube video or the unacademy video?
The unacademy vdo. I am not sure if it's paid or not but i am unable to sign up to that website because only 6 to 7 countries are eligible there and i am not from any of them. Actually here is the vdo link : link. And the website says join for free. I am not sure if i could join for free and get to see the vdo that way but i am not able to check it because i cant just sign up. If its still paid then i should go learn from somewhere else.
