Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputYou 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}.
