You have a real talent for explaining things in a clear and easy-to-understand way. Keep up the great work!

Errichto keep making videos of the contests ,this helps us to think about different approaches ,and how to analyse a question and to break it in sub tasks

Really loved the solution to E. Please keep on posting solutions. It's a great source of learning.

Seeing Errichto do videos again might encurage me to practise CP again stopping more than 2 years ago ❤❤❤

Glad you're back

Amazing explanation

will you do more MAP project videos for OIJ/OI and have you thought about doing some videos on this yourself?

What you use for explanation?

Bro please give me the suggestion I am able to come up with the solution but it becomes difficult for me to implement can you give some suggestion

Good job...

I would be very interessted in the genomic profiles of the best problem solvers, to generate a cofactor nutrition profile for problem solvers who want to get better, but have barriers in their eating habits or genomic profile. It would be although interessting to see, if there is maybe no base profile of genetic settings in the best problem solvers. nethertheless, i'm very thankful, that i have the priviledge to see you working on problems where i suck at all.

We can also do first problem like -- Input value in array Sort array Count total no of 1s Ans = n - (cntof1s/2); It should also give right ans

plz put on subtitle

Can I meet you when I will go to Poland?

In second question, if a==0 , b==3, c==3, d==0,The ans is 6,so many people did if a==0 cout
