Usage/Instructions

• I have used Fedora17 OS for solving these problems.

Note:-

• Problem-2 is related with parsing of a CSV file. While running test, it generates one error in country _ip_test.rb file.

 Errno::ENONT: No such file or directory - md5 -q IpToCountry.csv

• The following command mentioned in country_ip_test.rb file in problem_2 is not working as 'md5' command is not available for linux.

`md5 -q IpToCountry.csv`.strip 

• Please replace line-27 in country_ip_test.rb file of problem_2 with the following two lines to remove the error mentioned above.

 require 'digest/md5'
 assert_equal '22620fdd50ebaef84dd3d9521beb6a7c', Digest::MD5.hexdigest(File.read(Dir.pwd+"/IpToCountry.csv"))
