I'm not sure exactly how you're using NLog logging, but you may want to check that log messages are flushed immediately to disk (otherwise some messages may get cached and if your application crashes violently they get lost). Looking at your code in #1043 (comment), I can't see the ...
However, my concerns about the usability of clang in competitive programming were about things like this issue that was fixed surprisingly late (quadratic std::sort was fixed in 2021, even when C++11 had guaranteed O(nlogn)O(nlogn) sorting). I have not seen libstdc++ ignore the standard...

The Twin Primes Conjecture is Π2: for all n, there exists a p > n such that p and p + 2 are prime. To make this a Π1-sentence, we'd need to strengthen the conjecture by including an explicit lower bound—say, that there are at least log log log n twin primes less than n...
O(n^2) — used sorting to check median of pair in constant time O(nlogn) — related to counting inverses in permutation. And surprisingly someone came up with O(n) solution. So here is my question, can anyone tell me about this solution to the problem? I'm quite curious how this ...
For each pass through the array, at least one element falls into place, so it is necessary to make no more than n−1 passes, where n is the size of the array, to sort the array.Below is the pseudocode for bubble sort, which takes the array a[0..n−1] as input....
