as you can see matrix is not empty either

Try printing the size of the vector with cout, does it also print empty?

debugger on neovim ._.

[tardy barn]

which vector is empty?

oh the values

why are you flatting the matrix vector

ohh to sort it...

you can just not flatten the matric vector....

[plush geode]

no it doesn't . logic is perfectly fine

[plush geode]

i mean sure but my current issue isn't related to that ...

what sort function are you using?

[jagged mist]

I've seen similar issues when enabling debug containers/iterators with -D_GLIBCXX_DEBUG

Check your compiler flags, do you have that?

i include bits/stdc++ and use namespace std . i know this is bad but convenient for problem solving . that said this is the sort function i am using

template<typename _RandomAccessIterator>
    _GLIBCXX20_CONSTEXPR
    inline void
    sort(_RandomAccessIterator __first, _RandomAccessIterator __last)
    {
      // concept requirements
      __glibcxx_function_requires(_Mutable_RandomAccessIteratorConcept<
        _RandomAccessIterator>)
      __glibcxx_function_requires(_LessThanComparableConcept<
        typename iterator_traits<_RandomAccessIterator>::value_type>)
      __glibcxx_requires_valid_range(__first, __last);
      __glibcxx_requires_irreflexive(__first, __last);

      std::__sort(__first, __last, __gnu_cxx::__ops::__iter_less_iter());
    }

cpp functions are really unreadable to me but whatever

[plush geode]

i use this to run program

    vim.opt_local.makeprg = "g++ -g -std=c++17 -Wall -Wextra -o " .. output .. " " .. file

ignore the nvim stuff

i was just wondering if you were using a custom one that doesn't work
