数据结构二线性表的链式实现

本文展示了几个关于链表的操作实例,包括创建链表、按输入顺序存储整数、排序、合并及去重。程序实现了从键盘输入10个整数并保持输入顺序的链表,随机生成100个整数并按升序排序的链表,以及合并两个已排序链表并去重。此外,还涵盖了将链表分为正负数两类以及在循环双向链表中按序和逆序输出整数的方法。

1、从键盘输入10个整数放入链表,要求链表中的元素与输入顺序一致,然后输出该链表。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
struct node{
	int data;
	struct node* next;
};


struct node* createlist()
{
	struct node* headnode =(struct node*)malloc(sizeof(struct node));
	headnode->next=NULL;
	return headnode;
}

struct node* createnode(int data)
{   
   struct node* newnode=(struct node*)malloc(sizeof(struct node));
   newnode->data=data;
   newnode->next=NULL;
   return newnode;
}
void printlist(struct node* headnode)
{ 
  struct node* pmove=headnode->next;
  while (pmove)
  {
  	printf("%d ",pmove->data);
  	pmove=pmove->next;
  }
  printf("\n");
}


void charu(struct node* lastnode,int data)
{
	struct node* newnode=createnode(data);
	struct node* posnode=lastnode;
	while(posnode->next!=NULL)
	{
	posnode=posnode->next;
	}
	posnode->next=newnode;
}



int main(){
	int i,n;
	
	struct node* list=createlist();
	for(i=0;i<10;i++){  
	scanf("%d",&n);                           
	charu(list,n);}
	printlist(list);
	return 0;
}

2、随机生成100个随机整数并放入一个链表中,要求链表中的元素按从小到大顺序排列,然后输出该链表。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
struct node{
	int data;
	struct node* next;
};


struct node* createlist()
{
	struct node* headnode =(struct node*)malloc(sizeof(struct node));
	headnode->next=NULL;
	return headnode;
}

struct node* createnode(int data)
{   
   struct node* newnode=(struct node*)malloc(sizeof(struct node));
   newnode->data=data;
   newnode->next=NULL;
   return newnode;
}
void printlist(struct node* headnode)
{ 
  struct node* pmove=headnode->next;
  while (pmove)
  {
  	printf("%d ",pmove->data);
  	pmove=pmove->next;
  }
  printf("\n");
}


void charu(struct node* lastnode,int data)
{
	struct node* newnode=createnode(data);
	struct node* posnode=lastnode;
	while(posnode->next!=NULL)
	{
	posnode=posnode->next;
	}
	posnode->next=newnode;
}
void paixucharu(struct node* l,int x)
{
	struct node* newnode=createnode(x);
	struct node* p=l;
	while(p->next!=NULL&&p->next->data<=x)
	{
	p=p->next;
	}
	newnode->next=p->next;
	p->next=newnode;
	
}


int main(){
	int i,n;
	srand((int)time(NULL)); 
	struct node* list=createlist();
	for(i=0;i<100;i++){                              //2.随机数排序 
	n=rand()%100;
	paixucharu(list,n);}
	printlist(list);
	return 0;
}

3、将两个从小到大排列的链表合并为一个新链表(仍然有序排列),输出合并前的两个链表,输出合并后的链表,检查合并是否成功。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
struct node{
	int data;
	struct node* next;
};


struct node* createlist()
{
	struct node* headnode =(struct node*)malloc(sizeof(struct node));
	headnode->next=NULL;
	return headnode;
}

struct node* createnode(int data)
{   
   struct node* newnode=(struct node*)malloc(sizeof(struct node));
   newnode->data=data;
   newnode->next=NULL;
   return newnode;
}
void printlist(struct node* headnode)
{ 
  struct node* pmove=headnode->next;
  while (pmove)
  {
  	printf("%d ",pmove->data);
  	pmove=pmove->next;
  }
  printf("\n");
}


void charu(struct node* lastnode,int data)
{
	struct node* newnode=createnode(data);
	struct node* posnode=lastnode;
	while(posnode->next!=NULL)
	{
	posnode=posnode->next;
	}
	posnode->next=newnode;
}
void paixucharu(struct node* l,int x)
{
	struct node* newnode=createnode(x);
	struct node* p=l;
	while(p->next!=NULL&&p->next->data<=x)
	{
	p=p->next;
	}
	newnode->next=p->next;
	p->next=newnode;
	
}
void hebing(struct node* l1,struct node* l2,struct node* l3){
	while(l2->next!=NULL)
	{
	l2=l2->next;
	paixucharu(l3,l2->data);
	}

	while(l1->next!=NULL)
	{
	l1=l1->next;
	paixucharu(l3,l1->data);
	}
	
	
}

int main(){
	int i,n;
	srand((int)time(NULL)); 
	struct node* list1=createlist();
	struct node* list2=createlist();
	struct node* list3=createlist();
	for(i=0;i<5;i++){
	n=rand()%100;
	paixucharu(list1,n);}
	for(i=0;i<5;i++){
	n=rand()%100;
	paixucharu(list2,n);}                 //3.合并链表 
	
	hebing(list1,list2,list3);
	printlist(list1);
	printlist(list2);
	printlist(list3);
	return 0;
}

4、将两个从小到大排列的链表合并为一个新链表(仍然有序排列),若遇到相同的元素,则在合并时去掉重复元素。输出合并前的两个链表,输出合并后的链表,检查合并是否成功。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
struct node{
	int data;
	struct node* next;
};


struct node* createlist()
{
	struct node* headnode =(struct node*)malloc(sizeof(struct node));
	headnode->next=NULL;
	return headnode;
}

struct node* createnode(int data)
{   
   struct node* newnode=(struct node*)malloc(sizeof(struct node));
   newnode->data=data;
   newnode->next=NULL;
   return newnode;
}
void printlist(struct node* headnode)
{ 
  struct node* pmove=headnode->next;
  while (pmove)
  {
  	printf("%d ",pmove->data);
  	pmove=pmove->next;
  }
  printf("\n");
}


void charu(struct node* lastnode,int data)
{
	struct node* newnode=createnode(data);
	struct node* posnode=lastnode;
	while(posnode->next!=NULL)
	{
	posnode=posnode->next;
	}
	posnode->next=newnode;
}

void paixucharu(struct node* l,int x)
{
	struct node* newnode=createnode(x);
	struct node* p=l;
	while(p->next!=NULL&&p->next->data<=x)
	{
	p=p->next;
	}
	newnode->next=p->next;
	p->next=newnode;
	
}
int paixucharu2(struct node* l,int x)
{
	struct node* newnode=createnode(x);
	struct node* p=l;
	while(p->next!=NULL)
	{
	p=p->next;
	if(p->data==x)
	return 0;
	}
	p=l;
	while(p->next!=NULL&&p->next->data<x)
	{
	p=p->next;
	}
	newnode->next=p->next;
	p->next=newnode;
	
}
void hebing2(struct node* l1,struct node* l2,struct node* l3){
	
	
	
	while(l1->next!=NULL)
	{
	l1=l1->next;
	paixucharu2(l3,l1->data);
	}
	while(l2->next!=NULL)
	{
	l2=l2->next;
	paixucharu2(l3,l2->data);
	}

}


int main(){
	int i,n;
	srand((int)time(NULL)); 
	struct node* list1=createlist();
	struct node* list2=createlist();
	struct node* list3=createlist();
	for(i=0;i<5;i++){
	n=rand()%100;
	paixucharu(list1,n);}
	for(i=0;i<5;i++){
	n=rand()%100;
	paixucharu(list2,n);}                 //4.合并链表并且清除重复的数 
	
	hebing2(list1,list2,list3);
	printlist(list1);
	printlist(list2);
	printlist(list3);
	return 0;
}

5、随机生成100个整数存入链表,整数范围在[-100, 100]之间,输出该链表。将该链表分为两个,一个存放所有负整数,另一个存放所有非负整数,输出这两个链表。

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
struct node{
	int data;
	struct node* next;
};


struct node* createlist()
{
	struct node* headnode =(struct node*)malloc(sizeof(struct node));
	headnode->next=NULL;
	return headnode;
}

struct node* createnode(int data)
{   
   struct node* newnode=(struct node*)malloc(sizeof(struct node));
   newnode->data=data;
   newnode->next=NULL;
   return newnode;
}
void printlist(struct node* headnode)
{ 
  struct node* pmove=headnode->next;
  while (pmove)
  {
  	printf("%d ",pmove->data);
  	pmove=pmove->next;
  }
  printf("\n");
}


void charu(struct node* lastnode,int data)
{
	struct node* newnode=createnode(data);
	struct node* posnode=lastnode;
	while(posnode->next!=NULL)
	{
	posnode=posnode->next;
	}
	posnode->next=newnode;
}

void paixucharu(struct node* l,int x)
{
	struct node* newnode=createnode(x);
	struct node* p=l;
	while(p->next!=NULL&&p->next->data<=x)
	{
	p=p->next;
	}
	newnode->next=p->next;
	p->next=newnode;
	
}


void fenlei(struct node* l1,struct node* l2,struct node* l3){
	while(l1->next!=NULL)
	{
	l1=l1->next;
	if(l1->data<0)
	paixucharu(l2,l1->data);
	else
	paixucharu(l3,l1->data);
	}
}


int main(){
	int i,n;
	srand((int)time(NULL)); 
	struct node* list1=createlist();
	struct node* list2=createlist();
	struct node* list3=createlist();
	for(i=0;i<5;i++){
	n=rand()%200-100;
	paixucharu(list1,n);}
                                //5.正负数分类 
	
	fenlei(list1,list2,list3);
	printlist(list1);
	printlist(list2);
	printlist(list3);
	return 0;
}

6、随机生成10个整数存入一个循环双向链表中,然后按序输出这些整数和逆序输出这些整数。

#include <stdio.h>
#include <stdlib.h>
#include<time.h>
typedef struct DNode
{
    int data;
    struct DNode *next,*Previous;
}Node,*LinkList;

void InitList(LinkList *L)
{
    *L=(LinkList)malloc(sizeof(DNode));
      (*L)->data=0;
    (*L)->next=(*L)->Previous=*L;
}

void CreateLink(LinkList L,int n)
{   srand((int)time(NULL)); 
     
    LinkList p=L,q;
    while(n--)
    {   int x=rand()%200-100;
        q=(LinkList)malloc(sizeof(DNode));
        q->data=x;
        p->next=q;
        q->Previous=p;
        q->next=L;//尾插法
        L->Previous=q;
        p=q;
    }
}

void TraverseList(LinkList L,int i)
{   int x=0;
    LinkList p=L->Previous;
    LinkList q=L->next;
    while(x<i)
    {
        printf("%d ",p->data);
        p=p->Previous;
        x++;
    }
    printf("\n");
    x=0;
    while(x<i)
    {
        printf("%d ",q->data);
        q=q->next;
        x++;
    }
}

int main()
{
	srand((int)time(NULL)); 
    int n;
    LinkList L;
    InitList(&L); 
    CreateLink(L,10);  //0代表头节点的值,改变TraverseList的值改变输出的值
    TraverseList(L,10);
    return 0;
}
