You have coordinates of 2 points and need to find the distance between them.
Your program should accept as its first argument a path to a filename. Input example is the following
(25, 4) (1, -6) (47, 43) (-25, -11)
Print results in the following way.
You don't need to round the results you receive. They must be integer numbers between -100 and 100.
#!/usr/bin/env ruby -w def calculate_distance(x1, y1, x2, y2) Math.sqrt((x1 - x2)**2 + (y1 - y2)**2).to_i end ARGF.each_line do |line| x1, y1, x2, y2 = line.chomp.scan(/-?\d+/).map(&:to_i) puts calculate_distance(x1, y1, x2, y2) end
