Codeforces Round

Ended up 21th by the end of the contest. Update: It changed to 20th
I solved C and D too slowly and I made several stupid mistakes in all problems. The slow servers on CF also made it a bit worse :(

[@nikhillondhe5815]

Expecting your videos is becoming a habit now, lol. Nice!

[@brunokawka]

As a beginner myself, I really enjoyed this round's tasks. Too bad I didn't solve C and D in time :/ Your channel really motivates me to practice even harder.

[@abhishekranjansingh5348]

William, I'm following you since your codechef video editorial , and I feel enthusiastic from your videos. Be consistent like this man 😊😊

[@RakeshGupta-ft6cc]

Literally, I am searching internet since few days to get solutions to codeforces rounds. Keep doing this

[@scoopedcontent]

Good Job Bro You are now my motivation🙏🏻😘😍

[@aryandhuria6828]

For me its like a dream which is unachievable

[@prajjwalsahu793]

Can you make a video about your whole setup and configuration of vim

[@shamsuddohashameem9786]

Yeah would like to know how you can be so effective with vim editor.

[@mujahidulislam315]

Keep it up bro...

[@nikhiljindal4580]

what is the use of ~ in the for loop used in q2?

[@tmwilliamlin168]

In this context, it is the same as i>=0.

[@JJ-cy2fi]

@@tmwilliamlin168 Could we just use i without ~? Will it still work? Like for(int i =n-2; i; --i)?

[@JJ-cy2fi]

I think I got it! We need a value of 0 INCLUDED. If we just use n, this will mean strictly positive values considered, without the value of 0...

[@cheytackcal5626]

what a god

[@CuriousCI]

I have a question. You solved the first three problems like you already knew the solution: how? Does it happen often that the problems are really similar in your experience, or is it pure logic and reasoning?

[@ahmedramy3334]

Ionut Cicio experience i guess

[@tmwilliamlin168]

Yea, it's a lot of experience.

[@18PregnantAndProud]

the first problem is so easy

[@chinmayasahu5577]

[@the_crypter]

I am planning to get into competitive coding myself. Could you please tell me which resources or sites would be good for a beginner ?

[@tmwilliamlin168]

Codeforces, CodeChef, and Hackerrank are good sites. I plan to make videos explaining more

[@Ashish-dn1sc]

Which IDE do you use, basically I want to know the setup, I type on Hackerearth IDE during contests because the online compiler offers some features as int fa[n] = {0}, offline IDE gives error. Hope you reply.

[@shamsuddohashameem9786]

It's GVim IDE

[@moonpie24]
