Distance II

Your task is to calculate the distance between two $n$ dimensional vectors $x = \{x_1, x_2, ..., x_n\}$ and $y = \{y_1, y_2, ..., y_n\}$.

The Minkowski's distance defined below is a metric which is a generalization of both the Manhattan distance and the Euclidean distance.

\[
D_{xy} = (\sum_{i=1}^n |x_i - y_i|^p)^{\frac{1}{p}}
\]

It can be the Manhattan distance

\[
D_{xy} = |x_1 - y_1| + |x_2 - y_2| + ... + |x_n - y_n|
\]

where $p = 1 $.

It can be the Euclidean distance

\[
D_{xy} = \sqrt{(|x_1 - y_1|)^{2} + (|x_2 - y_2|)^{2} + ... + (|x_n - y_n|)^{2}}
\]

where $p = 2 $.

Also, it can be the Chebyshev distance

\[
D_{xy} = max_{i=1}^n (|x_i - y_i|)
\]

where $p = \infty$

Write a program which reads two $n$ dimensional vectors $x$ and $y$, and calculates Minkowski's distance where $p = 1, 2, 3, \infty$ respectively.

Input

In the first line, an integer $n$ is given. In the second and third line, $x = \{x_1, x_2, ... x_n\}$ and $y = \{y_1, y_2, ... y_n\}$ are given respectively. The elements in $x$ and $y$ are given in integers.

Output

Print the distance where $p = 1, 2, 3$ and $\infty$ in a line respectively.
The output should not contain an absolute error greater than 10-5.

Constraints

$1 \leq n \leq 100$

$0 \leq x_i, y_i \leq 1000$

Solution in C# (judge verdict: Accepted)

public class Hello
{
    public static void Main()
    {
        int num = int.Parse(System.Console.ReadLine());
        string[] x = System.Console.ReadLine().Split(' ');
        string[] y = System.Console.ReadLine().Split(' ');

        // p1-p3,???????¨????
        double p1 = 0;
        double p2 = 0;
        double p3 = 0;
        double p = 0;
        for (int i = 0; i < num; i++)
        {
            double diff = System.Math.Abs(double.Parse(x[i]) - double.Parse(y[i]));
            p1 += diff;
            p2 += System.Math.Pow(diff, 2.0);
            p3 += System.Math.Pow(diff, 3.0);
            p = System.Math.Max(p, diff);
        }

        System.Console.WriteLine(p1.ToString("F6"));
        System.Console.WriteLine(System.Math.Pow(p2, 1.0 / 2.0).ToString("F6"));
        System.Console.WriteLine(System.Math.Pow(p3, 1.0 / 3.0).ToString("F6"));
        System.Console.WriteLine(p.ToString("F6"));
    }
