Question: 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 is1 -> 2 -> 3 -> 4and you are given the third node with value3, the linked list should become1 -> 2 -> 4after calling your function...
Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Given linked list -- head = [4,5,1,9], which looks like following: image Example 1: Input: head = [4,5,1,9], node = 5 Output: [4,1,9] Explanation: You are giv...
Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Given linked list -- head = [4,5,1,9], which looks like following: Note: The linked list will have at least two elements. All of the nodes' values will be unique. The...
delete (t); return; } del(head->link, val); } Intuition: 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 p...

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...
题意:给一个将要删除的位置的指针,要删除掉该元素。被删元素不会是链尾(不可能删得掉)。 思路:将要找到前面的指针是不可能了,但是可以将后面的元素往前移1位,再删除最后一个元素。 1 /** 2 * Definition for singly-linked list. 3 * struct ListNode { ...
For the input, you should provide the entire linked list head and the node to be given node. node should not be the last node of the list and should be an actual node in the list. We will build the linked list and pass the node to your function. ...
