Doubly Linked-List C

This is a simple implementation of a doubly linked-list in C. Doubly linked-lists are a type of data structure that are similar to singly linked-lists, but they have a pointer to the previous node in addition to the next node. This allows for traversal in both directions.

Usage

// Create a linked-list
DoublyLinkedList *list = createDoublyLinkedList();

// Insert some data
insertAtBeginning(list, 1);
insertAtBeginning(list, 2);
insertAtBeginning(list, 3);
insertAtEnd(list, 4);
insertAtEnd(list, 5);
insertAtEnd(list, 6);

// Print the list
printList(list);

// Print the list in reverse order
printListReverse(list);

// Reverse the list
reverseList(list);

// Print the list
printList(list);

// Get the size of the list
printf("Size: %d\n", getSize(list));

// Get the data at the given index
printf("Data at index 2: %d\n", getDataAtIndex(list, 2));

// Get the index of the given data
printf("Index of 5: %d\n", getIndex(list, 5));

// Check if the list is empty
printf("Is empty: %s\n", isEmpty(list) ? "true" : "false");

// Delete the first node
deleteFirst(list);

// Delete the last node
deleteLast(list);

// Delete the node at the given index
deleteAtIndex(list, 2);
