                N-Grams Code Challenge
              
          
    Foxbox Digital N-Grams Code Challenge

This is a small programming problem to test your technical ability and coding style.
Instructions

Write a simple script to generate a set of n-grams from a string of text.  N-grams are a contiguous sequence of n words from a string of text, and have many applications from full-text search indexes to machine learning.
You'll generate a set of every permutation of contiguous n-grams from a string of text, from 1-gram to n-grams where n is the number of words in the string
Example


## enable_moped_logger.rb
# From Rails console, run the following and you'll see raw Moped queries for every Mongoid query!
Moped.logger = Logger.new(STDOUT)

## count_values_of_array.rb
food = ["bacon", "eggs", "cheese", "eggs", "bacon", "bacon", "bacon"]
food.inject(Hash.new(0)) {|h, k| h[k] += 1; h }.sort_by {|k,v| -1 * v}

# => [["bacon", 4], ["eggs", 2], ["cheese", 1]]

## rails_console_reload.rb
load "#{Rails.root}/lib/my_file.rb"
	# From Rails console, run the following and you'll see raw Moped queries for every Mongoid query!
	Moped.logger = Logger.new(STDOUT)
	food = ["bacon", "eggs", "cheese", "eggs", "bacon", "bacon", "bacon"]
	food.inject(Hash.new(0)) {\|h, k\| h[k] += 1; h }.sort_by {\|k,v\| -1 * v}

	# => [["bacon", 4], ["eggs", 2], ["cheese", 1]]
