splice

Description : The list::splice() is a built-in function in C++ STL which is used to transfer elements from one list to another

Example :

    // initializing lists 
    std::list<int> l1 = { 1, 2, 3 }; 
    std::list<int> l2 = { 4, 5 }; 
    std::list<int> l3 = { 6, 7, 8 }; 
  
    // transfer all the elements of l2 
    l1.splice(l1.begin(), l2); 
  
    // at the beginning of l1 
    std::cout << "list l1 after splice operation" << " "; 
    for (auto x : l1) {
        std::cout << x << " "; 
    }
  
    // transfer all the elements of l1 
    l3.splice(l3.begin(), l1); 
  
    // at the end of l3 
    std::cout << "\nlist l3 after splice operation" << " "; 
    for (auto x : l3) {
        std::cout << x << " "; 
    }
