My submission on the problem Parse Tree(C++14) failed to compile, and the error message is:

Can't compile file:

But when I was using C++11, there was no problem. My code is here:

I already solved over 130 problems,but when I open the problemset standings,I saw the number 126.And,sometimes,when I open it again,I see the correct number.I think this may be a bug.

At my opinion,tags are good for beginners.However,after someone learns programming for a period of time,he/she will find that tags are not good for him/her any more because they make problems pointless.And if someone doesn't login to Codeforces,the tags will automaticly show in the problem description.

I used to be a lover of this language.And this language is in the top 10 list in programming languages(according to the list now).If Codeforces really adds this language,I will feel happy.
