与Leetcode上翻转链表(206. Reverse Linked List)思路一致,只不过多了一个“prev”前节点的处理,这种题通过画图比较容易验证。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16DoublyLinkedListNode* reverse(DoublyLinkedListNode*head) {if(!head|| !head->next)returnhead; DoublyLinkedListNode* prev = nu...
remove(value): Removes the first node with the specified value from the list. find(value): Finds and returns the first node with the specified value. printList(): Prints the list from head to tail. printListReverse(): Prints the list from tail to head. getSize(): Returns the size of...

1. Firstly, we will Create a Node class that represents a list node. It will have three properties: data, previous (pointing to the previous node), and next (pointing to the next node). 2. Create a new class that will create a doubly linked list with two nodes: head and tail. The...
Doubly Linked List (DLL) is a complex data structure and an advanced version of a simple linked list in which the node has a pointer to the next node only. As we can traverse the elements in only one direction, reverse traversing is not possible. To solve this problem, a doubly-linked...
