You want to arrange n integers a_1, a_2, ..., a_{n} in some order in a row. Let's define the value of an arrangement as the sum of differences between all pairs of adjacent integers.

More formally, let's denote some arrangement as a sequence of integers x_1, x_2, ..., x_{n}, where sequence x is a permutation of sequence a. The value of such an arrangement is (x_1 - x_2) + (x_2 - x_3) + ... + (x_{n} - 1 - x_{n}).

Find the largest possible value of an arrangement. Then, output the lexicographically smallest sequence x that corresponds to an arrangement of the largest possible value.


-----Input-----

The first line of the input contains integer n (2 ≤ n ≤ 100). The second line contains n space-separated integers a_1, a_2, ..., a_{n} (|a_{i}| ≤ 1000).


-----Output-----

Print the required sequence x_1, x_2, ..., x_{n}. Sequence x should be the lexicographically smallest permutation of a that corresponds to an arrangement of the largest possible value.


-----Examples-----
Input
5
100 -100 50 0 -50

Output
100 -50 0 50 -100 



-----Note-----

In the sample test case, the value of the output arrangement is (100 - ( - 50)) + (( - 50) - 0) + (0 - 50) + (50 - ( - 100)) = 200. No other arrangement has a larger value, and among all arrangements with the value of 200, the output arrangement is the lexicographically smallest one.

Sequence x_1, x_2, ... , x_{p} is lexicographically smaller than sequence y_1, y_2, ... , y_{p} if there exists an integer r (0 ≤ r < p) such that x_1 = y_1, x_2 = y_2, ... , x_{r} = y_{r} and x_{r} + 1 < y_{r} + 1.
