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 PHP (judge verdict: Accepted)

<?php
	$n = trim( fgets(STDIN) );
	$x = explode( " ", trim( fgets(STDIN) ) );
	$y = explode( " ", trim( fgets(STDIN) ) );
	
	list( $Dxy, $Dxy2, $Dxy3, $Dmax ) = array_fill( 0, 4, 0 );
	for( $i=0; $i<$n; $i++ ) {
		$t = abs( $x[$i]-$y[$i] );
		$Dxy += $t;
		$Dxy2 += pow( $t, 2 );
		$Dxy3 += pow( $t, 3 );
		$Dmax = max( $t, $Dmax );
	}
	print $Dxy.PHP_EOL;
	print pow( $Dxy2, 1/2 ).PHP_EOL;
	print pow( $Dxy3, 1/3 ).PHP_EOL;
	print $Dmax;
