CF1105A.Salem and Sticks
Salem and Sticks
Salem gave you sticks with integer positive lengths .
For every stick, you can change its length to any other positive integer length (that is, either shrink or stretch it). The cost of changing the stick's length from to is , where means the absolute value of .
A stick length is called almost good for some integer if .
Salem asks you to change the lengths of some sticks (possibly all or none), such that all sticks' lengths are almost good for some positive integer and the total cost of changing is minimum possible. The value of is not fixed in advance and you can choose it as any positive integer.
As an answer, print the value of and the minimum cost. If there are multiple optimal choices for , print any of them.
Input
The first line contains a single integer () — the number of sticks.
The second line contains integers () — the lengths of the sticks.
Output
Print the value of and the minimum possible cost. If there are multiple optimal choices for , print any of them.
Note
In the first example, we can change into and into with cost and the resulting lengths are almost good for .
In the second example, the sticks lengths are already almost good for , so we don't have to do anything.
