Codeforces Mashups for Practice !!
By twoseven, history, 3 years ago, In English

Hey Codeforces, This blog is intended for those who want to practice virtual contests frequently. I have made a goal to practice in mashup contests as frequently as I can and till now I have participated in 70+ mashup contests along with a small group of other coders.

Today I thought of engaging more coders from the Codeforces community. And to achieve this I have a Discord, Telegram channel where I will be posting the invitation link for the mashup contest.

And also a Youtube channel where I will be posting the video editorials for the respective mashups after the contest. I hope it will be helpful for those who are looking for practicing a quality problemset and compete with other coders.

Note: Neither any of the problem gets repeated in future mashups nor you will be getting already solved problem.

UPD : Join the Codeforces Group

Here you will find all the virtuals till now and upsolve the problems for previous virtuals.

Hey,twoseven How do you make sure that "nor you will be getting already solved problem"?.

I tried using the ProblemHunter as mentioned in your youtube video. But I guess due to the codeforces site update, it is not working anymore.

    I am using problem hunter from the start... The issue is not due to cf site update, chrome driver updates almost every month. Do replace it with the new driver.

    --"How do you make sure that "nor you will be getting already solved problem"?." -> Till date, we had used 549 problems in 78 mashups and did few updates in bot which will never allow repeating problems in future virtuals unless the problems have 2 id's (div1 and div2).

    That bot finds only the problems which are not yet solved by you or any other participant.
