As with a singly linked list, the first node in a doubly linked list is called the head. The second and third nodes are assigned by using both the next and previous pointers on each node. The following image shows the resulting data structure. ![Doubly linked list diagram by Lasindi - ...
Your task is to implement a double linked list. Write a program which performs the following operations: insert x: insert an element with key x into the front of the list. delete x: delete the first element which has the key of x from the list. If there is not such element, you nee...
Now let's finally delete a node from a linked list. So let's say we have some other function that is finding a node we want to delete and has given us a pointer to exactly the node that we want to delete. We don't even need-- say the head is still globally declared. We don'...
