C++ DOUBLY LINKED LIST:
Implement the remove_between function for my code:
- This function removes the inserted/ added node in the add_between function.
Provided code:
class DoublyLinkedList : public List {
node* head;
node* tail;
int index;
node* create_node(int num, node* predecessor, node* successor) {
node* n = (node*) malloc( sizeof(node) );
n->element = num;
n->next = successor;
n->prev = predecessor;
return n;
}
void add_between(int num, node* predecessor, node* successor) {
node* newest = create_node(num, predecessor, successor);
predecessor->next = newest;
successor->prev = newest;
index++;
}
void remove_between(int num, node* predecessor, node* successor) {
///// CODE HERE
}
