When I copy my code, it comes with some blank characters inserted at the beginning of some lines which is giving compilation error.
My last submission: https://mirror.codeforces.com/contest/1196/submission/57904310
This gives error while compiling if I don't remove the blank characters present at all blank lines(ie 20,23,29..etc)

In every blank line it automatically put a character which cause error on compilation, if you remove that character then it compile successfully, this problem was not occurs before, but from some time it occurs, this problem also said by many users, hope to solve as soon as possible by MikeMirzayanov :)
Thank you for noticing! We'll try to fix it soon.
