your welcome brother :+1:

Can u make one for EXPGCD, i see u solved it also? :slight_smile:

yes I did solved that , but i used Mobius Inversion to derive the formula that i used , and most of my viewers don’t know about Mobius inversion.
So what I am thinking is to develop a number theory course , in which I would cover concepts like ETF , Segmented sieve and Mobius inversion as well.
And then problems like EXPGCD and other similar problems can be solved easily.


Looking forward to it! :slightly_smiling_face:

That’s great ! Hope to see it soon
