函数 C++ 找数组a中出现次数最多的值int f(int a[],int n){ int k,maxk = 0; int max = a[0]; for(int i = 0;i < n;i++) { k = 0; for(int j = 0;j < i;j++) { if(a[j] == a[i]) { k++; if(k >= maxk) { maxk = k;max = a[j];

链表实现多项式相加#include <stdio.h>#include <stdlib.h>struct polynomial{ float coefficient; int exponent;};typedef struct Node{ struct polynomial data; struct Node *next;}Node, *LinkList;LinkList Create(void);//分配内存空间void CreatePolynoma
