每天一算:Delete Node in a Linked List 题目 请编写一个函数,使其可以删除某个链表中给定的(非末尾)节点,你将只被给定要求被删除的节点。 现有一个链表 -- head = [4,5,1,9],它可以表示为: 4 -> 5 -> 1 -> 9 示例1: 输入:head = [4,5,1,9], node = 5 输出:[4,1,9] 解释:给定你...

Delete Node in a Linked List Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Supposed the linked list is 1 -> 2 -> 3 -> 4 and you are given the third node with value 3, the linked list...
You are given the node to be deleted node. You willnot be given accessto the first node of head. All the values of the linked list areunique, and it is guaranteed that the given node node is not the last node in the linked list. ...
We are passing node* (node pointer) as a reference to the 'del' function (as in node* &head).Suppose node containing 'val' is the first node, head = head->next changes the actual head in the main function which now points to the current beginning of the list (which was second ...
voiddel(node*&head,intval){if(head==NULL){cout<<"Element not present in the list\n";return;}if(head->info==val){node*t=head;head=head->link;delete(t);return;}del(head->link,val);}
This problem introduces a very interesting way to delete a node in the singly linked list. Usually, we use need to go to the previous node and let it point to the next next node, instead, we could just copy the next node and delete it. Delete 3 Firstly copy the next node, and then...
