Here someone suggest join discussion chat, but chat is inefficient to search through, explanations choppy and unorganized. But it would be beneficial for people who don't like being stuck on a problem for so long that they start getting frustrated to find the solution. I believe hitting newbie was an important phase of my competitive programming life. However, this is probably best resource for CSES as of now.

If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive. 1), problem: (A) k-Multiple Free Set solution and Binary search version Only then you can freely think about the problem and develop your independent algorithm design skills. It would not make sense that you can reach a top place by sending other people's solutions. But, this does not diminish the usefulness of virtual contests. https://www.youtube.com/watch?v=oY0PBQt36YM, Hopefully it will help you: https://github.com/abeaumont/competitive-programming/tree/master/cses, i found this one in github and i like the solutions https://github.com/ncduy0303/CSES---CSES-Problem-Set, The only programming contests Web 2.0 platform, 2020-2021 ICPC, NERC, Southern and Volga Russian Regional Contest (Online Mirror, ICPC Rules), Codeforces WatchR: 10K+ downloads on Google Play, Technocup 2021 Elimination Round 3 and Round #692 (Div. It is a fundamental question in learning algorithms whether it is possible to view hints or model solutions before solving a problem. It is very slow to write one blog for one question and then wait for someone to explain it. P.S. You’ll find me almost all technological medium by @jinnatul programming. I like to build up algorithms in an efficient and optimized way and write clean code.

Go to contest page, use a link "Participants solved this problem" (Статус - Codeforces Round #216 (Div. Codeforces Round 692 (Div. Analyzing your algorithm is pretty crucial in competitive programming. Solution codes, hints, explanations. 1, Div. Such things should not be important for learners. So, it's a win-win for both types of people. Yes, especially for such a problem set as CSES which is supposed to be educational, it is often hard for learning when faced with a problem without much public solution or explanation of any kind. For example: 1A - Theatre Square.cpp number of the problem is 1A. Here is my Solution for reference. Book is not enough for learners who stuck on problems. But it would be beneficial for people who don't like being stuck on a problem for so long that they start getting frustrated to find the solution. This is when I gave up the idea of quitting! In fact, it is extra discouraging to see such high statistics when they are stuck on problems without resources to help. Solve for the base case first, and then look for edge cases. If I want to learn 10's of problems in one day it is much easier to see the codes of other people rather than asking every problem. 2) Editorial. Here another user ask for discussion forum, and response is to read book. If anyone does not wants to share the solutions with public because they will abuse the leaderboard. Almost all of the judges have their solutions posted on Github. In fact, it is extra discouraging to see such high statistics when they are stuck on problems without resources to help. Codeforces #172 Tutorial xiaodao Contents 1 Problem 2A. To adjust the time limit constraint, solution execution time will be multiplied by 2. Can someone upload their solutions of the CSES problem set on github or any other site. follow the naming convention. Learners just seek a resource to aid them in improving skill. Here I sorted the integers in increasing order and took the difference of sorted first number and n’th number as answer that means I took the first n number of integers as the set of tiles.Then I check the next n adjacent numbers as the set if the difference of that sets n’th number and first number was less than ans then I updated the answer.
