#### Problem Description

QC is good at drawing. Now he wants to say numbers like “

But he 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 he 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.

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.

#### Output

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

#### Sample Input

3 3 1 2 3 5 2 1

#### Sample Output

14 30
