Ashishgup's blog

By Ashishgup, history, 11 days ago, In English,

I have been trying to cover a lot of commonly used Algorithms/Data Structures and maintain neatly written codes at my repository (since most codes are not neatly written in Competitive Programming in general, and I prefer neatly written codes):

https://github.com/Ashishgup1/Competitive-Coding/

Most of the codes are taken from various sources and already existing Coding Libraries, and many Algorithms/Data Structures are missing which I plan to add soon.

Hope you enjoy and feel free to point out any bugs you notice :)

Hi everyone!

It has been almost 2 years since I joined Codeforces, and it has been a great journey as a contestant. I now try to take a shot at problem-setting with my friend Mahir83.

With that said, I bring to your attention my new Codeforces Round #508 (Div. 2) that will take place on Sep/06/2018 18:35 (Moscow time). If your rating is less than 2100, this round will be rated for you; otherwise, you can participate out of competition.

I would like to thank Mahir83 for his help with preparing problems, _kun_ & 300iq for coordinating my round and Um_nik, senek_k, gritukan, Vovuh & BledDest for testing my problems. I would also like to thank MikeMirzayanov for Codeforces and Polygon platforms.

You will be given 6 problems and 2 hours to solve them. Scoring distribution will be announced later.

Good luck!

UPD: Scoring Distribution: 500-1000-1500-1750-2250-2750

UPD2: Editorial

These days, cases of cheating (reported or otherwise) go un-handled as can be seen from this blog. However, this is a cheating case that needs to be handled separately, so it is still somewhat understandable

But what about:

1) This case where the code is literally copy-pasted letter to letter with the difference being 2 spaces in the entire code?

2) These two submissions from yesterday's contest: 40441960 and 40428475 where there is not even a single character difference. Their codes for C are copied too, albeit with some modification of spaces.

In both of those cases, no-one was disqualified and I'm sure there must be more such cases.

Can we have some way of reporting these cheating cases that are then handled (rather than commenting on blogs or creating new blogs) and a better plagiarism checker?

Trying to open the Announcement Blogs or Tutorials of some of the past contests (such as: http://codeforces.com/contest/877) gives "Access Denied". What is the reason behind this? Is it a bug?

In the "Contests" tab, the change along the border of 2100 is shown as "became Candidate Master" both ways. I guess this should either be updated with the current rating system or be removed altogether (if the system only wants to reflect rating system changes from when it was introduced), because right now it is just weird.

CodeForces seems to have finally introduced a button for copying the sample input on the problem pages :D

I love the revamped look of the site and the new rating system which is pretty similar to CodeForces and TopCoder. I also like that they combined the ratings of Long Contests (Challenges) and Short Contests (Cook-offs and Lunchtimes) to form an overall rating and rank, while also maintaining separate ranks (country and global) for each of them.

I have noticed that quite a few people changed their username on CodeForces, but I can't figure out some of their original/previous usernames because of bad memory/changed profile picture accompanied with the changed name. Is there any method to do so?
