Increasing Array which is an Introductory Problem from CSES Problem Set by using the C++/CPP language. Yes I would love a place to find solutions! Update: Now the checker should work and hacking is possible again. But setting the EXACT SAME problem in different platforms has no use. I have developed a command line program just like "leetcode-cli" for CSES. I want to try the problems on my own first without any hints. Oh, i didn't notice that. 1, Div. EDIT: I have a better idea. 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. For instance my python3 implementation of https://cses.fi/problemset/task/1192 takes 1.5s on some inputs. Now both C++11 and C++17 are available, you can select the standard when submitting a code.

I think this slows down learning significantly compared to solving problems with editorials. I've tried all the optimizations I can think of (other than rewriting TreeSet) and I still TLE. 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. I think it is fair that everybody has the same languages available and the same time and memory limits. By Mahavir singh - c++, programming. You can implement the intended solution and it'll pass easily. 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 would encourage you to send feedback to Springer. I feel it is a nice feature that is lacking currently. The statement for Grid Paths says "from the upper-left square to the lower-right square," but the diagram and test data match "from the upper-left square to the lower-left square.". 2x or even 1.5x for Java suffices.
