设单链表的数据为互不相等的整数,建立一个单链表,并设计一个算法,找出单链表中元素值最大的结点。
要求:
(1)单链表的数据从键盘输入;
(2)输出单链表所有结点的数据和最大值结点序号。
#include "iostream" using namespace std; #include "malloc.h" #include "stdio.h" #define N 10 typedef int ElemType; typedef struct LNode { ElemType data; struct LNode *next; }LNode, *LinkList; int MaxNode(LinkList h) { int j, k; LNode *p, *q; if (h->next == NULL) return 0; q = h->next; p = q->next; k = 1; j = 2; while (p != NULL) { if (p->data>q->data) { q = p; k = j; } p = p->next; j++; } return k; }//MaxNode int output(LinkList h) { LNode *q; if (h->next == NULL) return 0; q = h->next; while (q != NULL) { cout << q->data << " "; q = q->next; } } void CreateLink(LinkList &h, ElemType a[], int n) { LNode *s, *r; int i; h = (LNode *)malloc(sizeof(LNode)); r = h; for (i = 0; i < n; i++) { s = (LNode *)malloc(sizeof(LNode)); s->data = a[i]; r->next = s; r = s; } r->next = NULL; } void main() { LinkList head; ElemType a[N]; int i, k; cout << "请输入一组数:" << endl; for (i = 0; i<N; i++) scanf_s("%d", &a[i]); CreateLink(head, a, N); cout << "所有数据:" << endl; output(head); cout <<endl << "最大值节点序号:" << endl; k = MaxNode(head); cout << k << " "; cout << endl; }
