P24906 [AtCoder] Happy Sequence
NOI
题目描述

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.

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.

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.

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.
