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 JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

  public static void main(String[] args) {
    Scanner stdin = new Scanner(System.in);
    int n = stdin.nextInt();
    int[] x = new int[n];
    for (int i = 0; i < n; i++) {
      x[i] = stdin.nextInt();
    }

    int[] y = new int[n];
    for (int i = 0; i < n; i++) {
      y[i] = stdin.nextInt();
    }

    for (int i = 0; i < 4; i++) {
      double D = 0;
      for (int j = 0; j < n; j++) {
        switch (i) {
          case 0:
            D += Math.abs(x[j] - y[j]);
            break;

          case 3:
            D = Math.max(D, Math.abs(x[j] - y[j]));
            break;

          default:
            D += Math.pow(Math.abs(x[j] - y[j]), i + 1);
            break;
        }
      }

      if (i == 1 || i == 2) {
        D = Math.pow(D, 1.0 / (i + 1));
      }

      System.out.println(D);
    }
