You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in c++17.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:

# Problem
There are no heroes in this problem. I guess we should have named it "To Zero".

You are given two arrays $$$a$$$ and $$$b$$$, each of these arrays contains $$$n$$$ non-negative integers.

Let $$$c$$$ be a matrix of size $$$n \times n$$$ such that $$$c_{i,j} = |a_i - b_j|$$$ for every $$$i \in [1, n]$$$ and every $$$j \in [1, n]$$$.

Your goal is to transform the matrix $$$c$$$ so that it becomes the zero matrix, i. e. a matrix where every element is exactly $$$0$$$. In order to do so, you may perform the following operations any number of times, in any order:

- choose an integer $$$i$$$, then decrease $$$c_{i,j}$$$ by $$$1$$$ for every $$$j \in [1, n]$$$ (i. e. decrease all elements in the $$$i$$$-th row by $$$1$$$). In order to perform this operation, you pay $$$1$$$ coin;
- choose an integer $$$j$$$, then decrease $$$c_{i,j}$$$ by $$$1$$$ for every $$$i \in [1, n]$$$ (i. e. decrease all elements in the $$$j$$$-th column by $$$1$$$). In order to perform this operation, you pay $$$1$$$ coin;
- choose two integers $$$i$$$ and $$$j$$$, then decrease $$$c_{i,j}$$$ by $$$1$$$. In order to perform this operation, you pay $$$1$$$ coin;
- choose an integer $$$i$$$, then increase $$$c_{i,j}$$$ by $$$1$$$ for every $$$j \in [1, n]$$$ (i. e. increase all elements in the $$$i$$$-th row by $$$1$$$). When you perform this operation, you receive $$$1$$$ coin;
- choose an integer $$$j$$$, then increase $$$c_{i,j}$$$ by $$$1$$$ for every $$$i \in [1, n]$$$ (i. e. increase all elements in the $$$j$$$-th column by $$$1$$$). When you perform this operation, you receive $$$1$$$ coin.

You have to calculate the minimum number of coins required to transform the matrix $$$c$$$ into the zero matrix. Note that all elements of $$$c$$$ should be equal to $$$0$$$ simultaneously after the operations.

## Input Format
The first line contains one integer $$$n$$$ ($$$2 \le n \le 2 \cdot 10^5$$$).

The second line contains $$$n$$$ integers $$$a_1, a_2, \dots, a_n$$$ ($$$0 \le a_i \le 10^8$$$).

The third line contains $$$n$$$ integers $$$b_1, b_2, \dots, b_n$$$ ($$$0 \le b_j \le 10^8$$$).

## Output Format
Print one integer — the minimum number of coins required to transform the matrix $$$c$$$ into the zero matrix.

## Note
In the first example, the matrix looks as follows:

111000111

You can turn it into a zero matrix using $$$2$$$ coins as follows:

- subtract $$$1$$$ from the first row, paying $$$1$$$ coin;
- subtract $$$1$$$ from the third row, paying $$$1$$$ coin.

In the second example, the matrix looks as follows:

221001221

You can turn it into a zero matrix using $$$5$$$ coins as follows:

- subtract $$$1$$$ from the first row, paying $$$1$$$ coin;
- subtract $$$1$$$ from the third row, paying $$$1$$$ coin;
- subtract $$$1$$$ from the third row, paying $$$1$$$ coin;
- subtract $$$1$$$ from $$$a_{2,3}$$$, paying $$$1$$$ coin;
- add $$$1$$$ to the third column, receiving $$$1$$$ coin;
- subtract $$$1$$$ from the first row, paying $$$1$$$ coin;
- subtract $$$1$$$ from $$$a_{2,3}$$$, paying $$$1$$$ coin.

Now solve the problem and return the code.
