How do you use the sort function for descending order in C++?

Sorting a vector in descending order in C++ To get a stable sort std::stable_sort is used. It is exactly like sort() but maintain the relative order of equal elements.

Which sorting algorithm is best for descending order?

Among the classical sorting algorithms, heap sort will do well when the input turns out to be (almost) sorted in descending order, as then the max-heap construction phase will involve (almost) no swaps (while the most swaps would occur when the input was already sorted in ascending order).

Which sorting is used in sort function in C++?

In more details it is implemented using hybrid of QuickSort, HeapSort and InsertionSort.By default, it uses QuickSort but if QuickSort is doing unfair partitioning and taking more than N*logN time, it switches to HeapSort and when the array size becomes really small, it switches to InsertionSort.
