Yes I would love a place to find solutions! I thought the purpose of the problem set was to be a collection of problems which can be used to practice the techniques explained in the books, not a collection of problems which forces everyone to either use cpp or learn some way to optimize their language. I can see an AC submission which just prints the input back without forming a palindrome. Ask your Doubts in Comment Section. Hey pllk Test 11 in coin combination 1 does not satisfy the input constraints. Thanks! Is it fair for Python users that they can't solve those problems without creating own data structures? So to figure out this type of query what else you could have done is, submitted you solution without this condition and checked those cases on which you get a WA and tried to figure out yourself why this condition matters. I have developed a command line program just like "leetcode-cli" for CSES. Do you mean the section titles? Remember, if you don't know how to solve one problem, look at others! Yes, it is faster indeed, but it still fails for some inputs. In the future, we will add many more problems, and our goal is to create a comprehensive problem set that has 1000 high quality problems. 1 + Div. It includes solutions to both practice and contest problems from: ¡Acepta el reto! Clearly, this is much harder than a copy and paste. As there is a statistics of the users which sorts them by solved problems, it motivates people to solve more problems to achieve higher places. Java code can be very fast if you have proper I/O and only use primitive types and arrays. P.S. I didn't know it gives RE verdict for MLE. But setting the EXACT SAME problem in different platforms has no use. Contribute to ankitpriyarup/CSES_ProblemSet_Solution development by creating an account on GitHub. I'm not saying it's impossible to find tricks to make it work in python, but I don't think it's the point, we just want problems on which to apply what is explained in the handbook. I should have verified that a valid original string exists (the checker should have too ¯\_(ツ)_/¯). It may be very difficult or impossible to find a specific problem from some other site. Thanks, indeed the checker didn't work correctly and an invalid test was added. Unfortunately, some users cheat by sending an incorrect solution and then "hacking" it and adding a useless test. You have indeed listed some possible reasons that Java TLEs. Well, one important point is that Python is not always a good choice in competitive programming and it may be more difficult to solve some problems using it. MikeMirzayanov for Polygon and Codeforces platforms. Do you think it's fair that cpp users can just use their std::set and solve problems easily while java users have to either use TreeSet but heavily optimized or even write their own TreeSet? it would be good if a discussion forum is created. You should be able to solve at least most of the problems in Java if you use efficient I/O and avoid creating lots of objects etc. For most of the problems there will be editorial in Codeforces. It should be faster. UPD: Seems no original string exists corresponding to the input case bb#aaa. In fact, child 3 gives one unit of food to child 1 and one unit of food to child 2. There is a new feature: you can now hack submissions and improve the quality of tests. Explanation: Child 1 gives one unit of food to child 3, and child 2 gives one unit of food to child 3. Thank you for reporting this, this should be fixed now. I don't think that everybody should create their own platform because they can control user experience better. Maybe you use too much memory? SpentoO → If my rating is around 1400, then how should I prepare myself for IOI 2022? Thanks to the 1s TL, when I'm trying to solve a problem, I spend more time thinking about whether or not I'll be able to get away with a solution with some optimizations than actually thinking on the solution itself. Make all solutions that AC also AC in Java 3. The statement for Monsters says $$$1 \leq n,m \leq 2500$$$, but when i try making n=1001 i get invalid input(the same test with n=1000 and the last line removed doesn't get invalid input)... Also for monsters, my output is exactly the same as the expected one for test 10, but it fails with wa. It is true that they may provide hints. He wants to do it and so do tens of other platforms. Test quality? Platform like codeforces, leetcode, CSES will provide you testcase on which your submission is failing. The topics and algorithms introduced there are awesome!! I think is a problem with Springer they rather have differentiate prices by country. Would it be possible to have pdf versions of the problems? I think the explanation confuses the arrays a and b. Exactly. There should be one system with thousands of problems. I checked if a positive cycle is visible from both 1 and n (In case of n, I used the reversed adjacency list).
