这个代码咋运行不出来😂

#include <stdio.h>
#include <math.h>
int main()
{
int n,i;
double m, max=0, min=1000,sum=0,b;
scanf("%d", &n);
for (i = 1; i <= n; i++)
{
scanf("%lf", &m);
sum = sum + m;
if (m >= max)
{
max = m;
}
if (m <= 1000)
{
min = m;
}
}
sum = sum - max - min;
b = sum / (n - 2);
printf("%.2lf", b);
return 0;
}
