  • Divide the weights

    Given n weights , you are asked to split those weights into 2 groups so that the difference between those weights is minimal.

    Input

    The first line of the input contains a single integer n (1 ≤ n ≤ 20).
    The next line contains n space-separated integers (1 ≤ ).

    Output

    The program should print the minimal possible difference between the two groups.

    Examples

    Input
    Output
    3 3 2 1
    0
    5 1 2 3 4 7
    1

    Explanation

    1. First group → 3, second group → 1 + 2 = 3
    1. First group → 1 + 7 = 8, second group → 2 + 3 + 4 = 9
     
    Hint
    You can try to split the weights in all the possible ways and calculate the minimum possible difference.
