Subject: [SOLUTION] Quiz #76

I sincerely hope I am doing this correctly, as...

   (1) I have never posted to a mailing list.
   (2) I have never participated in Ruby Quiz
   (3) I really hope I am posting at the right time, place, etc

I apologise if I did this incorrectly.

Here was my solution to the Ruby Quiz:

#By Jesse H-K
#On the date of Sunday April 23, 2006

class String
	#Take a string, and scramble the center of each word.
	def scramble
		#find each word and replace it with...
		gsub(/\w+/) do |word|
			if (1..3) === word.length
				#..the word if it's length is 1, 2, or 3. These words cannot be 
scrambled.
				word
			else
				#...the first character, plus the scrambled middle, and ending with 
the last character.
				word[0].chr + word[1..(-2)].scan(/./).sort_by { rand }.join + 
word[-1].chr
			end
		end
	end
end

while str = gets
	puts str.scramble
end


I don't have any formal education with programming, but this was an 
easier challenge, so I thought I'd try my hand at it.

Since nothing in the String could be affected besides words, I figured I 
would use the built in String#gsub . I simply find each word using the 
regex /\w+/ (which will find 1 or more letters), and return it if its 
length is from 1 to 3. This is because these words cannot be altered in 
any way. For all the other words, I take the first character, and 
seperate the middle of the string into and Array of letters using 
String#scan. This Array is randomely shuffled with Enumerable#sort_by, 
and join back tpogether into a String. Lastly, the final character is 
appended.

To use my example, either run with a file as a command line argument, or 
enter text as an input-result loop.

This was a great way to get involved in Ruby Quiz. Thanks to all those 
that organize it.
