Time Limit: 1 sec

 

The Problem

In 2-D every points is located as pair of (x, y).

You will be given two points, point A and point B. If a line is drawn through A to B what will be the length of the line.

Note: Distance of two points = √((x1 – x2)2 + (y1 – y2)2)

 

The Input

The Input file contains series of lines. Each line contains 4 integer numbers X1 (X1 <=100), X2 (X2 <=100), Y1 (Y1 <=100), Y2 (Y2 <=100). The input file is terminated by EOF

 

The Output

For each line of input the output will show the length of the line rounded to 2 decimal point in a separate line.

 

Sample Input

10 5 25 20
