2.1 Write code to remove duplicates from an unsorted linked list.Follow upHow would-solve this problem if a temporary buffer isn't allowed?This problem allows us to remove duplicates from the unordered list, and there are two similar problems in
Copy codeThe Code is as follows: @ echo off
: Purpose:
: In SearchNet. TXT, each row has only one number. The number of repetitions of each number is counted and sorted from high to low by the number of repetitions.

One: Remove duplicates from Sorted ArrayTopic:Given a sorted array, remove the duplicates in place such, all element appear only once and return the new L Ength.Do the allocate extra space for another array, and you must does this on place with
Given a sorted linked list, delete all duplicates such this each element appear only once.For example,Given 1->1->2 , return 1->2 .Given 1->1->2->3->3 , return 1->2->3 .Idea: This problem is similar to the previous one, the concrete solution is as
#include #define SUM 3+4//macro definition is intact using used for test4#include //used for Test8~9#include //used for Test8~9void Test () {//array outputint a[5]={1,2,3,4,5};printf ("Array output,look,please...\n");int a[10];int i;//for (int
Let's take a look at two common questions about the number of duplicates.
1. There are 101 numbers, which are the numbers between [1,100]. One of them is repeated. How can we find the number of duplicates? What is the time complexity and space
Given a sorted linked list, delete all duplicates such this each element appear only once.For example,Given 1->1->2 , return 1->2 .Given 1->1->2->3->3 , return 1->2->3 .Subscribe to see which companies asked this questionSolution: Set two pointers

Important:(1) If SQL is created without specifying a type then the default nonclustered index(2) Clustered and nonclustered indexes can have duplicate records, and unique indexes cannot have duplicate records.(3) The primary key defaults to a
