By duncan7, history, 2 months ago, In English,

Hey everyone, I hope you are doing good. I was thinking of starting a mashup contest series in which I will be creating a mashup contest every day at some time (which we all can choose) and that contest will have 4 questions (1 div2B (1500), 2 div2C's (1600) and 1 div2D(1700)) and 2 hours to attempt those. Right after the contest we can discuss the solutions and do that every single day (except when an official contest is there). I feel that this way we can get more practise and having a group who want to practise similar things will keep us motivated. Let me know what do you guys think about this.

PS: This is targeted for beginners (cyans who wanna be blue). Everyone is welcome for this tho.

Based on the response I will start creating contests from today onwards. Thanks

UPD: So looks like I am not allowed to create a mashup contest. I was able to create a mashup right before this announcement. Can someone tell me why this is happening? Hoping they dont take my right to create a blog post too. But anyway I will be posting vjudge links for those problems until mashups dont get fixed.

Thanks to abdstar for creating the contests on mashups on my behalf since I did not have access (or if it was taken)

DAY 0 : May 11 2020 Time for contest : 9.30 IST (duration : 2 hours) mashup link :Contest 1 (it has 3 C (1600) and 1 D (1700) of previous contests)

So the contest is over. I am sharing the problem numbers : (849C, 1288C, 1284C, 579D) https://codeforces.com/contest/849/problem/C and so on. You can search for the editorials by going to the problem link.

Will update on when I will make the next mashup. DAY 1 : May 13 2020 Time for contest : 9.30 IST (duration: 2 hours) mashup link :Contest 2 It has 3 problems sorted in order of difficulty.

DAY 2: May 18 2020 Time for contest : 9.30 IST (duration : 2 hours) mashup link : Contest 3 It has 3 problems sorted in order of difficulty.

Hello, I received suggestions from a few people to make a discord group since they wont be checking this blog that often so I have created a discord server where we can discuss a suitable time for mashup and discuss our solutions after the mashup. Join Here

can we this do for atcoder beginner problems 1 — C,2-D and 1-E ,i guess that will be more beneficial and educational as compared to codeforces because the question set there is better then codeforces one or we can do one day codeforces and the other day atcoder.

      i have seen people who solve atcoder C and D they usually solve C of codeforces in minutes and personally also i feel that atcoder is better if we want to speed up our solving of cf C

              so i was only able to make first problem , bad performance.like today contest is more mathematical,observational and adhoc type so these type of problems helps to develop your problem solving skills and Atcoder has a lot of problems like these.you must have seen people solved thousands of problems and still pupil or cyan have you wondered why?not because they have less logical thinking but because they have not developed it and if you see 2000 rated problems the first part in them is the observation and then comes your algorithm and data structure part so if you have good practice on solving adhoc,math and constructive algorithms problems then you will see a spike in your performance because you have learned to make observations which is the key part and atcoder problems are beautiful which require more of observations and brain and less implementation.But anyway today's contest was wonderful in that regard.

                I have seen many people say the same thing regarding atcoder.

                But atcoder doesn't support as many features as codeforces. For eg.

                1. No problem tags. (Big problem)
                2. No problem rating. So, if I want to train myself on a single topic, say dp, there is no way for me to find dp problems of the difficulty that I want to solve. To keep my practice in an organized way, ie. to sovle problems of difficulty just higher than my level and of some specific topic, I find codeforces as the best.

                Do you know of any workaround of above issues because I also want to try out atcoder now because I see so many people recommending it

                  see tentative rating of atcoder problems in terms of cf though this can change a little bit in every round C(900-1100),D(1100-1500),E(1600-1800) F(1800-2000) you dont get the feature of topic wise practice for that you can use cf. but atcoder have simple statements great editorial written from the point of view of a beginner and beautifully framed observational problem requiring basics of graph,dp.

                  I know about this website but the issue of no problem tags is still not solved.

Hey! I really like what you're trying to do here, and I would like to participate. My only question is: How will I receive updates for future contests, because I'd hate to miss one of them.

Edit: Typo.
