You are given an array of $n$ integers. Your task is to calculate for each window of $k$ elements, from left to right, the minimum total cost of making all elements equal.
You can increase or decrease each element with cost $x$ where $x$ is the difference between the new and the original value. The total cost is the sum of such costs.
Input
The first input line contains two integers $n$ and $k$: the number of elements and the size of the window.
Then there are n integers $x_1,x_2,\ldots,x_n$: the contents of the array.
Output
Output $n-k+1$ values: the costs.
Constraints
- $1 \le k \le n \le 2 \cdot 10^5$
- $1 \le x_i \le 10^9$
Example
Input:
8 3
2 4 3 5 8 1 2 1
Output:
2 2 5 7 7 1
