身高体重指数 题解

sort排序+结构体，代码如下

#include <iostream>
#include <algorithm>
using namespace std;
struct node{
    int k;
    double h;
    int id;
    double BMI;
}a[1010];
bool cmp(node x,node y){
    return x.BMI>y.BMI;
}
int main(){
    int n;
    cin >> n;
    for (int i=1;i<=n;i++) cin >> a[i].k;
    for (int i=1;i<=n;i++) cin >> a[i].h;
    for (int i=1;i<=n;i++) a[i].id=i;
    for (int i=1;i<=n;i++) a[i].BMI=a[i].k/(a[i].h*a[i].h);
    sort(a+1,a+n+1,cmp);
    for (int i=1;i<=n;i++) cout << a[i].id << " ";
    return 0;
}
