std::stable_sort: Sort elements preserving order of equivalents. Sorts the elements in the range[first,last) into ascending order, like sort, but stable_sort preserves the relative order of the elements with equivalent values. std::partial_sort:Partially sort elements in range. Rearranges the e...

This binary predicate takes two arguments and returns true if the two arguments are in order and false otherwise. This comparator function must impose a strict weak ordering on pairs of elements from the sequence. For more information, see Algorithms. Remarks The range referenced must be valid; ...
In the following program, we take an integer vector inv1and sort this vector in ascending order usingstd::sort()function ofalgorithmlibrary. main.cpp </> Copy #include <iostream> #include <vector> #include <algorithm> using namespace std; ...
Note: You are not suppose to use the library's sort function for this problem. Follow up: A rather straight forward solution is a two-pass algorithm using counting sort. First, iterate the array counting number of 0's, 1's,and 2's, then over write array with total number of 0's,...
The C++ standard library contains a huge set of tools for you to use. You should learn them and use them rather than re-writting the wheel.std::sort()is a good example but the standard already has function to build and maintain a heap you don't need to write that yourself ei...
#include <cpp-sort/probes.h>max_for_sizeAll measures of presortedness in the library have the following static member function:template<typename Integer> static constexpr auto max_for_size(Integer n) -> Integer;It takes an integer n and returns the maximum value that the measure of presorted...
