I'm new on codeforces, and rarely use c++. Maybe the question was already discussed, but i cannot find anything except this.
Today i first time used c++ on the contest. And got message kind of "your code was not submitted, do not use %lld".
Why is it bad idea to use %lld in 2018? Maybe this message is rudiment, and it is good time to dismiss it forever?
Is it normal to not accept compilable code 1 second before end of the contest? Of course, now i see checkbox "submit anyway", but spent last seconds on testing and had no time to resubmit =(
