6942.Sliding Window Cost

Time Limit: 1s Memory Limit: 512MB

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 Format(From the terminal/stdin)

The first 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.

  • $1 \le k \le n \le 2 \cdot 10^5$
  • $1 \le x_i \le 10^9$

Output Format(To the terminal/stdout)

Output $n-k+1$ values: the costs.
