yesterday there was a div2 contest,i was pretty confident since ive trained alot.so i decided to join.

after 5 minutes,i am able to solve A with paper.i have the informal proof.and i decided to code it out.turns out it fails the second pretest.i was testing for another random tc to see whether my approach is correct.turns out my approach is correct yet im unable to solve it until the contest ends.

after the contest,i saw the editorial.the editorial is slightly different than my approach but ive done the math and it was the same.now im suspecting that c++ is actually broken.why i say? because it cant handle decimals correctly.

i think most people has a potential but theyre unable to achieve it because of broken languages like c++.maybe someone can recommend me another language thats as fast as c++ and can handle numbers correctly?
