Hi Codeforces Community,

In recent Div3. round on CodeForces I secured a rank 1541 among more than 20K participants and finally became Specialist on Codeforces. It took me almost a year to finally turn Cyan on Codeforces.

I would like to thank AyuAnchor and i_pranavmehta bhaiya for helping and guiding me. Also, special mention to a aayush_chhabra, aman_m42, 9.86960440109,The_MazeRunner and titia whose codes in python have helped me to a great extent. I would like to extend my thank to the codeforces community who have been very supportive (especially the python users).

The next step is Expert on Codeforces. I humbly request everyone to share tips/ suggestions which they might have, so that I quickly hit my next target of becoming Expert.

Some take-aways from the journey till now:

  1. You can be competitive while still being a kind person : Everyone whom I have reached out have always helped me in some or the other way.

  2. Good Things Take Time: Even if you practice a lot, you are bound to have bad days, where nothing will work in favour of you. So keep grinding and practicing and to those who think they are unable to improve, you will see progress soon.

Siiiuuuu,

Hello everyone, This is about today's (Feb 28th) Codeforces Educational Rounds contest.

I usually code in python and use the same template that I am using today to solve in the contests. But my code output in my compiler was different but in codeforces output it was way different, This happened to me in both the questions today: Question A and B. Also, when I submitted the same code without any template usage, my code got accepted. I am attaching the screenshots below for your reference. Please let me know if anything can be done in order to avoid negative delta.

Also, how did it happen only during this contest only and not in any other contests inspite of me using the same template in all other contests and submissions. Any help in regard to this would be appreciated.

Problem A: VS Code Output  Problem A: Wrong answer according to CF

Problem A: CF Accepted submission

Problem B: VS Code Output

Problem B: Wrong answer according to CF

But when I submitted the same code as in my other submission which was showing wrong answer according to CF compiler, it got accepted.

Here's the accepted code link: https://mirror.codeforces.com/contest/1796/submission/195355146

Hello Everyone,

I am trying to solve the problem E from Codeforces Beta Round #91 (Div 1. only). I am facing issues in getting it accepted. It is giving me TLE on test case 62. I am not sure why is this happening, can anyone please help me resolve the same.

I think it might be because of the func I have used in lazy segment tree class. If anyone has any suggestion or update feel free to write it down in the comments.

Here is my submission and this is the lazy segment tree.

Hi Everyone,

I am interested on problems on segment trees which have appeared in relatively new contests. I am asking this because I wish to learn segment trees and moreover the blogs which are 3-7 years old have a very few python submissions for the given problem. I am a user who submits in python and would like to know the problems from relatively new contests since at present there are more users who submit in python and their solution can work as stepping stones when I am practicing this data structure.

I tried using tags in the problem set but that doesn't help, so I decided to write a new blog. I request you to not put old blogs in the comment as very few of them have any python solutions.

Thank you very much for your help.

P.S. : By relatively knew I mean the period from 2021 may-present (1.5 / 2 years or so).

It seems there is only Python-3 and Python-2 options. But I have seen users submitting in PyPy3 (7.3.0). Can anyone suggest when can we expect PyPy3 on AtCoder?

Thanks!
