All solutions have been rejudged with the current time limit. Also, few more tests have been added. 10 authors have got AC while 23 other have lost.

I have replaced standart C# input functions with my low level parse method and got Accepted. Is this the goal of that rejudgement?

Well, I just resubmitted the previous solution with visual c++.
I do every query O(1) operations and use scanf and printf. I think the version of your g++ compiler is not that good. There were some troubles with scanf and printf at some new versions of g++ compiler.
