For each case, the first line contains one integer N(1≤N≤100) indicating the number of squares.
Second line contains N integers ai(1≤ai≤100)represent the side length of each square. No squares will overlap.
Input ends with N = 0.

Output

For each case, output the total area in one line.

问题简述：（略）

问题分析：（略）

程序说明：不知道为什么在UVALive6336中出现WA，但是在HDU4450中是AC。

题记：程序员经常遇见郁闷的事情。

AC的C++语言程序如下：

/* UVALive6336 HDU4450 Draw Something */

#include <iostream>
#include <stdio.h>

using namespace std;

int main()
{
    int n, m, sum;
    while (scanf("%d", &n) != EOF && n) {
        sum = 0;
        while(n--) {
            scanf ("%d", &m);
            sum += m * m;
        }

        printf ("%d
", sum);
    }

    return 0;
}
