You are given $N$ integers; the $i$\-th of them is $A_i$. Find the maximum possible sum of the absolute differences between the adjacent elements after arranging these integers in a row in any order you like. ## Constraints * $2 \leq N \leq 10^5$ * $1 \leq A_i \leq 10^9$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $N$ $A_1$ $:$ $A_N$ [samples]

21

When the integers are arranged as $3,8,1,6,2$, the sum of the absolute differences between the adjacent elements is $|3 - 8| + |8 - 1| + |1 - 6| + |6 - 2| = 21$. This is the maximum possible sum.
