My solution in ruby:

Code: Select all

file = File.new("rfc3280.txt", "r")
dict = Hash.new(0)
while (line = file.gets)
	line.scan(/[^\w]([\w]{9})[^\w]/) { |match|
		dict.store(match, dict[match].succ)
	}
end
puts dict.index(dict.values.max)
file.close

My solution in ruby by doing some math with the ASCII table: input = "Guvf zrffntr vf rapelcgrq va ebg 13. Lbhe nafjre vf svfupnxr." input.each_byte { |x| # lower case letters if (65..90) === x print (65 + (x - 52) % 26).chr # capital letters elsif (97..122) === x print (97 + (x - 84) % 26...

My tiny ruby solution:

Code: Select all

require 'rubygems'
require 'chunky_png'
image = ChunkyPNG::Image.from_file('didactrgb.png')
color = ChunkyPNG::Color.to_truecolor_bytes(image[0,0])
color.map! { |x| x.to_s(2).rjust(8, '0') }
puts color.join.to_i(2)

My solution in ruby:

Code: Select all

input = ["9f", "c7"]
input.map! {
	|x| x.to_i(16)
