My submission 271237759 for the problem 1994B almost mathes submission 27121751 Our Solutions do match almost exactly the same, however neither do I used Ideone or any platform from where I can copy his/her code. I even don't know whom that account belongs to. It seems like a co-incidence since the solution was simple that it matched almost exactly. Now I feel very bad . Please anyone, help out here and tell me what to do?
