Implement the function below
void swap(int pos1, int pos2) {}
Inital code to be completed:
class LinkedList : public List { node* head; node* tail; int index;
node* create_node(int num) { node* n = (node*) malloc(sizeof(node)); n->element = num; n->next = NULL; return n; }
public: LinkedList() { index = 0; head = NULL; tail = NULL; }
int add(int num) { addTail(num); return index; } int get(int pos) { node* currnode = head; int count =0; while (currnode != NULL){ count++; if (count == pos){ return currnode -> element; }else{ currnode = currnode -> next; } } return -1; } int size() { return index; } void swap(int pos1, int pos2) { } // WARNING! Do not modify this method below! // Doing so will nullify your score for this activity. void print() { node* currnode = head; if (head == NULL && tail == NULL) { cout <> return; } while (true) { cout < currnode-="">element; if (currnode == tail) { cout <> return; } cout < "="" -=""> "; currnode = currnode->next; } }};
