#include <iostream>
#include <functional>
#include <{{{1}}}>
 
std::ostream& operator<<(std::ostream& ostr, const std::{{{1}}}<int>& list)
{
    for (auto &i : list) {
        ostr << " " << i;
    }
    return ostr;
}
 
int main()
{
    std::{{{1}}}<int> list = { 8,7,5,9,0,1,3,2,6,4 };
 
    std::cout << "before:     " << list << "\n";
    list.sort();
    std::cout << "ascending:  " << list << "\n";
    list.sort(std::greater<int>());
    std::cout << "descending: " << list << "\n";
}

الخرج:

before:      8 7 5 9 0 1 3 2 6 4
ascending:   0 1 2 3 4 5 6 7 8 9
descending:  9 8 7 6 5 4 3 2 1 0

[تعديل] Complexity

N · log(N) comparisons, where ‎N‎ is the size of the container.
