C++ :

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

int main(){
	int n,x,a[100],i,s = 0,max = 0,min = INT_MAX;
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>a[i];
		s = s + a[i];
		
		if(a[i] > max) max = a[i];
		if(a[i] < min) min = a[i];
	}
	sort(a,a+n);
	
	double v = (s - max - min) * 1.0 / (n - 2);
	cout<<fixed<<setprecision(1)<<v<<endl;
	for(i = 1;i <= n - 2;i++){
		cout<<a[i]<<" ";
	}
}

Python :

n=int(input())
s=list(map(int,input().split()))

s.sort()
s=s[1:len(s)-1]
print("%.1lf"%(sum(s)/len(s)))
print(" ".join(list(map(str,s))))
