数据结构实验之链表四:有序链表的归并
Time Limit: 1000 ms Memory Limit: 65536 KiB
Problem Description
分别输入两个有序的整数序列(分别包含M和N个数据),建立两个有序的单链表,将这两个有序单链表合并成为一个大的有序单链表,并依次输出合并后的单链表数据。
Input
第一行输入M与N的值; 第二行依次输入M个有序的整数; 第三行依次输入N个有序的整数。
Output
输出合并后的单链表所包含的M+N个有序的整数。
Sample Input
6 51 23 26 45 66 9914 21 28 50 100
Sample Output
1 14 21 23 26 28 45 50 66 99 100
Hint
不得使用数组!
拆开重建,连节点前先比较,找出较小的一个作为节点;
#include#include struct node{ int data; struct node *next;};int main(){ struct node *head, *tail, *p, *q, *head2; head = (struct node *)malloc(sizeof(struct node)); head->next = NULL; head2 = (struct node *)malloc(sizeof(struct node)); head2->next = NULL; int i, m, n; scanf("%d %d",&m,&n); tail = head; for(i=0; i data); p->next = NULL; tail->next = p; tail = p; } tail = head2; for(i=0; i data); p->next = NULL; tail->next = p; tail = p; } p = head->next; q = head2->next; tail = head; while(p&&q){ if(p->data data){ tail->next = p; tail = p; p = p->next; } else{ tail->next = q; tail = q; q = q->next; } } while(p){ tail->next = p; tail = p; p = p->next; } while(q){ tail->next = q; tail = q; q = q->next; } p = head->next; while(p->next){ printf("%d ",p->data); p = p->next; } printf("%d\n",p->data); return 0;}
