It looks like djm03178 (and, to be fair, some other users too) uses some kind of automated tools that detect solutions using unordered_set or unordered_map, and then send hack tests in bulk. From my perspective, hacks that exploit programming language's internal bugs are generally unsportsm...
My Python and C++ solutions for the Codeforces Bark to Unlock problem 868A. Includes the problem solving logic and speed benchmarks.
A possible (but more "expensive") strategy should be writing solutions in different languages and set different TL value for each one. I agree that this issue is important (see editorial comment for 424D - Biathlon Track for example), but I cannot figure a possible, fair solution for that...

The task is count how many solutions to put N queens in NxN board. I have tried to thought every possible case to improve the performace, but it take almost 50s to run with N = 15. Here's what I've do... Add condition to where clause eloquent relation ...
In the second line of the output print one string t of length n — a nice garland obtained from the initial one with minimum number of recolors. If there are multiple optimal solutions, print any of them. Examples input 3 BRB output ...
In order to cut off efficient solutions from inefficient ones in this problem, the time limit is rather strict. Prefer to use compiled statically typed languages (e.g. C++). If you use Python, then submit solutions on PyPy. Try to write an efficient solution. ...
On the first line print a single integer — the minimal possible m. On each of the next n lines print four space separated integers representing the i-th set. Neither the order of the sets nor the order of integers within a set is important. If there are multiple possible solutions with...
