#include <iostream>#include <string>#include <vector>#include <algorithm>#include <list>#include <iterator>#include <cmath>#include <deque>#include <cstring>#include <forward_list>using namespace std;void fun(list<int> lst, deque<int> & q1, deque<int> & q2) {    for(auto i : lst) {        if(i&1) {            q1.push_back(i);        }        else {            q2.push_back(i);        }    }   }void print(deque<int> deq) {    for(auto i : deq) {        cout << i << " ";    }    cout << endl;}int main() {    list<int> ilst = {0, 1, 2, 3, 4, 5, 6, 7, 8};    deque<int> ideq1;    deque<int> ideq2;    fun(ilst, ideq1, ideq2);    cout << "This is deque_1: " << endl;    print(ideq1);    cout << "This is deque_2: " << endl;    print(ideq2);    return 0;}

Outpt

This is deque_1: 1 3 5 7 This is deque_2: 0 2 4 6 8
