Problem Description

      Wangpeng is good at drawing. Now he wants to say numbers like “521” to his girlfriend through the game draw something.      Wangpeng can’t write the digit directly. So he comes up a way that drawing several squares and the total area of squares is the number he wants to say.      Input all the square Wangpeng draws, what’s the number in the picture?

Input

      There are multiple test cases.      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.

Sample Input

41 2 3 433 3 30

Sample Output

3027

 

 

题目又臭又长，其实就是n个数的平方和。
