Problem:
Distance

Write a program which calculates the distance between two points P1(x1, y1) and P2(x2, y2).

Input

Four real numbers x1, y1, x2 and y2 are given in a line.

Output

Print the distance in real number. The output should not contain an absolute error greater than 10-4.

Sample Input

0 0 1 1

Sample Output

1.41421356

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);

        double x1 = sc.nextDouble();
        double y1 = sc.nextDouble();
        double x2 = sc.nextDouble();
        double y2 = sc.nextDouble();

        System.out.printf("%f\n", Math.sqrt(Math.cbrt(x2 - x1) + Math.cbrt(y2 - y1)));
        sc.close();
    }
}
