The first line contains the integers $N$ and $K$ (1 ≤ $N$ ≤ $1000$), (1 ≤ $K$ ≤ $1000$).
The second line contains $N$ integers T ~i~ (-10^9^ ≤ T ~i~ ≤ 10^9^).

For tests worth $20$ points, $K = 1$.
For tests worth $30$ more points (1 ≤ $N$ ≤ $100$), (1 ≤ $K$ ≤ $100$).

For tests worth $20$ point, $K = 1$.
