Greetings to all,

I was solving this problem https://codeforces.net/contest/2074/problem/A, and submitted 2 codes in morning time. In morning, the second submission showed accepted and 1st one was failed.

But when I checked just 10 mins before, the second submission was in the queue status. So I again submitted the similar code (with one space), then it showed accepted.

Is there any problem in the server or is this some kind of bug, found out by mistake?

Does anyone knows more about this?

Image is attached for the reference.

I recently started using Node JS for programming, and I had written code that take input from stdin (command prompt) in windows. The difficulty arises here is that I go on inputting values and it didn't stopped (i.e. didn't reached the end). I searched over internet and found some saying that use CTRL-D or CTRL-V, but both is not working for me. Is there anything missed up or any other method to resolve it.

Any help would be appreciated. Thanks to community.
