Veshy is struggling in data management class. Veshy forgot how to make a box and whisker plot, so he wants you to tell him the important values to make the plot of the data points . He gives you: the **minimum**, **maximum**, (Quartile 1 or median of the first elements), (Quartile 2 or median of the entire data), and (Quartile 3 or median of the last elements) of the sorted list.

For example, if the data set was , the important values in their respective order would be: 1, 10, 3, 5.5, 8

Another example, if the data set was , the important values in their respective order would be: 1, 11, 3, 6, 9

#### Constraints

In all tests,

All numbers are guaranteed to be whole numbers.

#### Input Specification

The first line contains a number, , the number of data points.

The second line contains numbers separated by spaces, the data points Veshy gives you:

Note: the data points are not guaranteed to be in sorted order.

#### Output Specification

Output the minimum, maximum, , , , in that order separated by spaces on a single line.

Note: your answer will be judged as correct if it is within an absolute or relative error of .

#### Sample Input 1

```
10
1 2 3 4 5 6 7 8 9 10
```

#### Sample Output 1

`1 10 3 5.5 8`

#### Sample Input 2

```
11
1 2 3 4 5 6 7 8 9 10 11
```

#### Sample Output 2

`1 11 3 6 9`
