Recently saw Linus in the interview mentioned a way to delete nodes in a single-linked list, and said that people do not understand the method of the pointer, the exact words are as follows:At the opposite end of the spectrum, I actually wish more people understood the really core low-level kind of coding. Not big, complex stuff like the lockless name lookup, but simply good use of pointers-to-pointers etc.

1. Description of the problemGiven a single linked list, delete its Countdown k node. For example, given a linked list: 1 → 2 → 3 → 4 → 5 , delete its second-to-last node and change to 1 → 2 → 3 → 5 。 It can be assumed that the reciprocal K-node is always present.2. Methods and
C # The way to traverse list and delete an element, what method do you use to implement the first reaction? Foreach? ForIf it's foreach, then congratulations, you're wrong. If you're thinking of using for, then you're just a step away from success.the correct approach is to use a for reverse traversal , which is deleted according to the condition . Below we use code to demonstrate foreach,for

Let's take a list of elements of a string as an example, and delete the elements:>>> l = [‘no surfing‘, ‘flippers‘] 1 Law One: Remove (val)>>> l.remove(‘no surfing‘)>>> l[‘flippers‘] 1 2 3 (1) The parameter of remove () is a specific element value, not an index, (2) If you know the index, how to use Remove to delete
The following code implements the sequential insertion of a single-linked list, the deletion of linked list elements, the output of a linked list//Mylink.h code#ifndefMylink_h#defineMylink_h#includeiostream>using namespace std;struct node{intData; Node*Next;}; ClassList{ Public:List() {Head=NULL; };voidInsert (int item);voiddel (int item);voidShow ();Private: nod
Remove Nth Node from End of ListGiven A linked list, remove the nth node from the end of the list and return its head.For example,Given linked list:1->2->3->4->5, and n = 2.After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.Idea:
Given a linked list, delete the nth node in the list and return the head node of the linked list.Sample ExampleGive the list 1->2->3->4->5->null and n = 2.After you delete the second-to-last node, the list becomes 1->2->3->5->nul

Given a sorted list, delete all nodes that contain duplicate numbers, leaving only the numbers in the original linked list that do not recur.Example 1:Input: 1->2->3->3->4->4->5 output: 1->2->5Example 2:Input: 1->1->1->2->3 output: 2->3Idea: This topic is not the same as the previous one, because it does not leave repeating elements. My first thought was to trave
