求解QAQ，为什么最后两个点WA了

#include<iostream>
#include<cstdio>
using namespace std;

inline int check(double x)

    cnt=0;
    for(int i=1;i<=n;++i)
    {
        cnt+=a[i]/x;
    }
    if(cnt>=k) return 1;
    else return 0;
}
int main()
{
    scanf("%d%d",&n,&k);
    for(int i=1;i<=n;++i)
    {
        scanf("%lf",&a[i]);
    }
    double l=0,r=100010,mid,eps=0.001;
    while(r-l>=eps)
