In my std::list, i have 10 elements, and i want to move the number 1000 to the back of the list.
https://leetcode.com/playground/gucNuPit
is there a better way, a 1 liner using std::move, back inserter or any other C syntax to achieve this with consciously?
// Move the number 1000 to the end of the list
#include <iostream>
#include <algorithm>
#include <list>
using namespace std;
int main() {
list<int> myList({2,3,4,1000,5,6,7,8,9,10});
cout << "List before " << endl;
for(auto e : myList)
cout << e << " ";
// get iterator to the number 1000 in the list
list<int>::iterator findIter = std::find(myList.begin(), myList.end(), 1000);
int val_to_move_to_end = *findIter;
myList.erase(findIter);
myList.push_back(val_to_move_to_end);
cout << endl << endl << "List after " << endl;
for(auto e : myList)
cout << e << " ";
return 0;
}
CodePudding user response:
You can use the std::list::splice(..)
to achieve this
myList.splice(myList.end(), myList, std::find(myList.begin(), myList.end(), 1000));
