Description

Given a sequence of $n$ integers, output their sum, maximum value, minimum value, and the sequence sorted in descending order (with duplicates removed).

Input Format

The first line contains an integer $n$ ($1 < n ≤10^4$).
The second line contains $n$ integers $a_i$ ($1 ≤a_i ≤10^4$).

Output Format

The first line outputs an integer representing the sum.
The second line outputs an integer representing the maximum value.
The third line outputs an integer representing the minimum value.
The fourth line outputs a sequence of integers separated by spaces, representing the sequence sorted in descending order (with duplicates removed).
