There are $$$n$$$ fishermen who have just returned from a fishing trip. The $$$i$$$-th fisherman has caught a fish of size $$$a_i$$$.
The fishermen will choose some order in which they are going to tell the size of the fish they caught (the order is just a permutation of size $$$n$$$). However, they are not entirely honest, and they may "increase" the size of the fish they have caught.
Formally, suppose the chosen order of the fishermen is $$$[p_1, p_2, p_3, \dots, p_n]$$$. Let $$$b_i$$$ be the value which the $$$i$$$-th fisherman in the order will tell to the other fishermen. The values $$$b_i$$$ are chosen as follows:
For example, let $$$n = 7$$$, $$$a = [1, 8, 2, 3, 2, 2, 3]$$$. If the chosen order is $$$p = [1, 6, 7, 5, 3, 2, 4]$$$, then:
You have to choose the order of fishermen in a way that yields the minimum possible $$$\sum\limits_{i=1}^{n} b_i$$$.
The first line contains one integer $$$n$$$ ($$$1 \le n \le 1000$$$) — the number of fishermen.
The second line contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$1 \le a_i \le 10^6$$$).
Print one integer — the minimum possible value of $$$\sum\limits_{i=1}^{n} b_i$$$ you can obtain by choosing the order of fishermen optimally.
