PROGRAMMING:The first k numbers

Input n, K and n positive integers no more than 10000, and output the first k numbers from large to small
###Input format:
There are two integers n k in the first row
The second line contains n positive integers separated by a space
###Output format:
There are only K positive integers in a row, separated by a space
###Input example:
```in
10 3
1 2 8 2 34 52 3 4 9 7
```
###Output example:
```out
52 34 9
```
30% of data: 2 < = n < = 100, 1 < = k < = n
70% of data: 2 < = n < = 1 000, 1 < = k < = 100, K < = n
100% data: 2 < = n < = 10 000, 1 < = k < = 100, K < = n
