In this case, a new node is to be inserted before the current head node, i.e. , every time the node that got inserted is being updated to the head node. Such insertion can be done using following steps.Update n
，效率较低。所以ArrayList不适合做任意位置插入和删除比较多的场景。因此，java集合中又引入了LinkList，...
Structure of node doubly linked list is a list that contains links to links to next and previous nodes. Doubly linked list allows traversal in both ways typedef struct*node ; { void *data; struct node *next; struct node *prev; } node; Dummy head nodes Eliminates the special ca...
In linked lists, the insertion point plays a crucial role in maintaining the correct order of the elements. When inserting a new element into a linked list, you need to adjust the links between the existing nodes to include the new element at the desired position. The insertion point determin...

Example 1: Input: head = [4,2,1,3] Output: [1,2,3,4] Example 2: Input: head = [-1,5,3,4,0] Output: [-1,0,3,4,5] Constraints: The number of nodes in the list is in the range [1, 5000]. -5000 <= Node.val <= 5000Accepted...
