This is about 845B - Люба и билет from educational round 27.
My code got AC for C++14 34715622 and TLE for C++11 34715609. Can anyone tell me why? Diagnostics also TLEs, so I couldn't use that to check for undefined behaviour.

I think culprit is slow
to_string()
.I resubmitted your code as 34719330 with
string x(to_string(i))
call replaced byunder C++11 5.1.0, and it works in ~170 ms.
Presumably implementation of
to_string()
was slow in version 5.1.0 of compiler and improved at some version <= 6.4.nice, thanks a lot :)
this is irrelevant but which version of CLion are you using for Jhelper. Did you buy one?
2017.2 you can get it for free with a university email address
