Let's say I have something like this below:
#include <iostream>
#include <list>
using namespace std;
int main()
{
list<int> mylist{ 1, 5, 3, 2, 4 };
// sort
mylist.sort();
// printing the list after sort
for (auto it = mylist.begin(); it != mylist.end(); ++it)
cout << ' ' << *it;
return 0;
}
However, if I do that, the original list is permanently changed. I know there are a lot of ways to do it. But specifically I want to know how I can sort it without making a copy of the original list explicitly. I want to do it with a function that is passed by value so that changes will be temporary.
