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 Ruby (judge verdict: Accepted)

num = STDIN.gets.to_i
line0 = STDIN.gets.split(" ")
vec0 = Array.new(num) { |i|  i = line0[i].to_i}
line1 = STDIN.gets.split(" ")
vec1 = Array.new(num) { |i|  i = line1[i].to_i}

max = 0.0
for i in 1..3 do
  output = 0.0
  for j in 1..num do
    output += (vec0[j - 1] - vec1[j - 1]).abs ** i
    if i == 1 then
      if j == 1 then
        max = (vec0[j - 1] - vec1[j - 1]).abs
      else
        d = (vec0[j - 1] - vec1[j - 1]).abs
        if d > max then
          max = d
        end
      end
    end
  end
  puts sprintf("%.6f", output ** (1.0 / i))
end

puts sprintf("%.6f", max)
