# Sensical Sentence Scrambler
# ---------------------------

# This short program takes any word longer than three characters and randomly shuffles all the characters
# except for the first and the last. Strangely enough, sentences are still quite readable like this.

# **Usage**
# Save the file on your computer as 'scramble.rb'.
# From the command line, run `ruby scramble.rb "Here's my sentence!"`, and it should output 
# the scrambled version below.

# **Support**
# If you are having trouble with this, have questions about how it works, or anything else, feel free 
# to email me at jeff.escalante@carrotcreative.com

sentence = ARGV.first.split(" ")
result = []

sentence.each do |word|
  if word.length > 3
    result << "#{word[0]}#{word[1..word.length-2].split("").shuffle.join()}#{word[word.length-1]}"
  else
    result << word
  end
end

puts result.join(" ")
