Codeforces DIV2 Round 641 B and C video editorials

here you can find editorial for

Problem B. Orac and models

Code : Problem B

Problem C. Orac and LCM

Code : Problem C

Note : Code for problem C discussed in video can be optimized , I am leaving that to the viewer.


Please do div2F :slight_smile: . The editorial’s logic seems too twisted to understand :sweat_smile:.

I am planning to make video on E first

I will work on F after E for sure
