Sample Ruby Coding [on hold]

I have given a test which i need to complete:

Sample ruby coding - using the core libraries only. All times should be in UTC.

The idea is to see how you write ruby and how you think about solving problems. Please add further tests where appropriate. You can use the repl script to run IRB on your_ruby.rb .

• fizzbuzz - takes an integer as the argument and then returns an array of results up to that number.

• smallest_rectangle_of_aspect - takes an aspect ratio (height/width) and a rectangle (array [width, height]) and works out the smallest rectangle of that aspect ratio that contains a rectangle of those dimensions.

• parse_time - takes a string in the form HH:MM and works out how many seconds into the day it is.

• finish_time_for_day / start_time_for_day - takes a date/time object and a hash in the form { day => [starts, ends], ... }, where day is the abbreviated english name for the day, starts and ends are times in the format accepted by parse_time. It returns the start/finish time as a time object for that day.

• calculate_completion_time - takes a time, a number of hours (num_hours) and a hash of opening hours. If I place my order at placed_at time, then this returns the earliest point at which (1) the shop is open and (2) has been open for a total of num_hours since I placed my order. So if I place my order 1 hour before closing time and it takes 2 hours to process, then this will rollover 1 hour into the next working day.

• duckduckwhy - this scrapes duckduckgo.com to get the first N results for the specified phrase, using Net::HTTP .

and here is ruby file your_ruby.rb

module YourRuby

module_function

def fizzbuzz(max) 

end

def smallest_rectangle_of_aspect(ratio, rectangle)

end

def parse_time(str)

end

def finish_time_for_day(date, opening_hours)

end

def start_time_for_day(date, opening_hours)

end

def calculate_completion_time(placed_at, num_hours, opening_hours)

end

def duckduckwhy(str, num_results)

end

end

and here is repl script file:

#!/usr/bin/env ruby

 $: << File.join(File.expand_path(File.dirname(__FILE__)), 'lib')

 require 'net/http'

 require 'irb'

 require 'your_ruby'

 ARGV.clear

 def reload!

  load 'lib/your_ruby.rb'
end

 Y = YourRuby

 def why(results_count = 5)

   Y.duckduckwhy('whytheluckystiff', results_count)

 end

 def r(*args)

  Y.smallest_rectangle_of_aspect(*args)

 end

 IRB.start
