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://codeforces.me/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)
