为什么不对啊，，，，

#include<iostream>
#include<cstdio>
#include<cstring>
#include<algorithm>
#include<cmath>

using namespace std;
int n;
int h[301]={0};

int main(){
	scanf("%d",&n);
	for(int i=1;i<=n;i++)  scanf("%d",&h[i]);
	sort(h+1,h+n+1);
	int top=1,tail=n-1;
	int ans=0;
	ans+=h[n]*h[n];
	while(top<=tail){
		ans+=(h[tail+1]-h[top])*(h[tail+1]-h[top]);
		ans+=(h[tail]-h[top])*(h[tail]-h[top]);
		top++;tail--;
	}
	printf("%d",ans);
	return 0;
	
}
