Write a tool that can run on the commandline and tell you if a password is one of the 1,000 most commonly used passwords. It should read the passwords from a file on the local file system. Make sure to use the best data structures and algorithm you can think of.

Use this list of common passwords: https://github.com/DavidWittman/wpxmlrpcbrute/blob/master/wordlists/1000-most-common-passwords.txt

Running the program should look something like this:

$ checkpassword foo
#=> Not common password

$ checkpassword football
#=> Common password

Given an array or list of strings containing phone numbers, create a function called parse_numbers that outputs the number’s country and phone number in E.164 format. E.164 format is a universal format for phone numbers: +{country_code}{phone_number}. Example: the American number 414-534-1207 would be represented as +14145341207. You may use any tool, data structure, or library you find useful to complete the task.

A list of country codes can be found here: https://gist.github.com/jnankin/23162bd54d1017938a6ce6a366eee65f

Sanitize all strings for characters that are not E.164 compliant. For numbers in the input that do not begin with a plus sign, if they are 10 digit numbers, consider them to be American and prepend a +1. If there are not 10 digit numbers, they can be assumed to be in E.164 format without the plus.

Bonus points for unit tests on the parsing logic.

# Example input:
4145341207
+14145341207
(414) 534-1207
497113804761
+27177123841

# Example output:
United States +14145341207
United States +14145341207
United States +14145341207
Germany +497113804761
South Africa +27177123841

Write a command-line tool that finds the live weather for a zip code.

$weather {zip code}
#=> {description} {max temp} degrees Kelvin

$weather 80202
#=> Cloudy 293 degrees Kelvin

Write a server that opens up a port, accepts a number then calculates and returns a valid FizzBuzz response.

Validating it should look something like this:

$telnet 0.0.0.0 5555
Trying 0.0.0.0...
Connected to 0.0.0.0.
Escape character is '^]'.
1 ← sent from command-line
1 ← response from server
2 ← etc...
