NULL){p p-next;}p-next t;}return head;}//顺序输出void print(node * head){node * p head;while (p ! NULL){cout p-data ;p p-next;}cout endl;}//递归void reversePrint(node * p){if (p ! NULL){reversePrint(p-next);cout p-data ;}}//栈void reversePrint2(node * head){stack s;while (head ! NULL){s.push(head-data);head head-next;}while (!s.empty()){cout s.top() ;s.pop();}}int main(){node * head NULL;for (int i 1; i 5; i){head add(i, head);}print(head);reversePrint(head);reversePrint2(head);system(pause);return 0;}逆序输出可以用三种方法: 递归栈逆序后输出。最后一种接下来讲到。2.单链表逆序实例代码如下#include#include#includeusing namespace std;typedef struct node{int data;node * next;}node;node * add(int n, node * head){node * t new node;t-data n;t-next NULL;if (head NULL){head t;}else if (head-next NULL){head-next t;}else{node * p head-next;while (p-next ! NULL){p p-next;}p-next t;}return head;}//循环node * reverse(node * head){if (head NULL || head-next NULL){return head;}node * p1 head;node * p2 head-next;node * p3 NULL;head-next NULL;while (p2 ! NULL){p3 p2;p2 p2-next;p3-next p1;p1 p3;}head p1;return head;}void print(node * head){node * p head;while (p ! NULL){cout p-data ;p p-next;}cout endl;}//递归node * reverse2(node * p){if (p NULL || p-next NULL){return p;}node * newHead reverse2(p-next);p-next-next p;p-next NULL;return newHead;}int main(){node * head NULL;for (int i 1; i 5; i){head add(i, head);}print(head);head reverse(head);print(head);head reverse2(head);print(head);system(pause);return 0;}这里链表逆序用了两种方法循环递归。读者最容易理解的方法就是在纸上自己画一下。希望本文所述实例对大家的数据结构与算法学习能有所帮助。
