奥运排序问题
https://www.nowcoder.com/practice/100a4376cafc439b86f5f8791fb461f3
本题需要5个排序 分别对金牌 奖牌 金牌人口比例 奖牌人口比例。
同时还要保证与输入时的顺序相同 所以要在结构体中定义顺序 并在输入时对顺序赋值。
还有对每一次排序之后排名的确定 需要对chazhi变量清0来保证排名的正确 我个人感觉这点很容易被忽视。
以下是代码：
#include<stdio.h>
#include<math.h>
#include<string.h>
struct medal
{
int gold;
int medal;
float population;
float gold_scale;
float medal_scale;
int tag;//用于记录最小排名方式
int paiming[4];
int shunxu;
}medal[100000];
int main()
{
int n,m,i,min;
int chazhi;
int paiming;
void quicksort1(struct medal medal[],int low,int high);//生命4种排序方式 每次排序都确定一种排序的
void quicksort2(struct medal medal[],int low,int high);//最终位置 同时寻找最高排名
void quicksort3(struct medal medal[],int low,int high);//
void quicksort4(struct medal medal[],int low,int high);//
void quicksort5(struct medal medal[],int low,int high);
while(scanf("%d%d",&n,&m)!=EOF)
{
for(i=0;i<n;i++)//输入金牌数 奖牌数 人口 并计算对应的比例 并且加上标记来为每次排序后找前后
{
scanf("%d %d %f",&medal[i].gold,&medal[i].medal,&medal[i].population);
medal[i].gold_scale=medal[i].gold/medal[i].population;
