Problem Statement

Integer sequences $A, B$ and $C$, each of length $N$, are given. Snuke is happy if and only if the following condition is met.

• For every integer $x$, $\\sum_{1 \\leq i \\leq N} |A_i-x| \\leq \\sum_{1 \\leq i \\leq N} |B_i-x|$ holds.

He decided to change at least $0$ elements of $A$ to become happy. It costs him $C_i \\times (A_i-t)^2$ to change $A_i$ to $t$. Here, $t$, the value after the change, should be an integer as well.

Find the minimum possible sum of costs in order for Snuke to become happy.

Constraints

• $1 \\leq N \\leq 2 \\times 10^5$
• $0 \\leq A_i \\leq 2 \\times 10^5$
• $0 \\leq B_i \\leq 2 \\times 10^5$
• $1 \\leq C_i \\leq 5$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$N$ $A_1$ $A_2$ $\\cdots$ $A_N$ $B_1$ $B_2$ $\\cdots$ $B_N$ $C_1$ $C_2$ $\\cdots$ $C_N$

Output

Print the answer.

Sample Output 1

6

After the following operations, the sum of costs is $6$.

• Change $A_1$ to $2$. This change costs $1 \\times (0-2)^2=4$.
• Change $A_3$ to $3$. This change costs $2 \\times (4-3)^2=2$.

After the operations, $A=(2,1,3)$ holds, which makes Snuke happy. It is impossible to achieve the goal with sum of costs less than $6$, so the answer is $6$.
