Using std::sort The std::sort function is commonly used to sort a vector in C++. By default, it sorts the elements in ascending order, and it modifies the original vector. Example Here's the C++ code to sort a vector using std::sort. We call std::sort(v.begin(), v.end()) to...
But std::sort using quick sort algorithm. It's pick element and put lower element at begin and bigger element at end. Then recursive sort. So, if we will pick long vector it will be compared O(len(curr arr)) size. hmm, ok, my words are true until C++11 since C++11 it's using ...

Marowka34 investigated sorting algorithm proposed by Cormen35 which is vector-based quicksort algorithm. This work is implemented using process-based and thread-based models. However, it did not exhibit good scalability because of its overhead. Gebali et al.36 proposed a Parallel ...
