题目叙述不清，需要特判 

#include<bits/stdc++.h>
using namespace std;

const int N = 110;
int a[N];
int n;

int main()
{
	cin >> n;
	
	int a_max = 0, a_min = 1010;
	for(int i = 0; i < n; i ++)
	{
		cin >> a[i];
		a_max = max(a_max, a[i]);
		a_min = min(a_min, a[i]);
	}

	if(a_max == a_min) //特判
	{
		for(int i = 1; i < n - 1; i ++)
			cout << a[i] << " ";
		return 0;
	}
	
	for(int i = 0; i < n; i ++)
		if(a[i] != a_max && a[i] != a_min)
			cout << a[i] << " ";
			
    return 0;
}
