Hello Shannon,

Wednesday, December 18, 2002, 5:19:50 PM, you wrote:

if lexicon.size % 2 == 0
  hash = Hash[ *lexicon ]
  hash.update Hash[ *(lexicon[1..-1] + [0]) ]
else
  hash = Hash[ *(lexicon + [0]) ]
  hash.update Hash[ *lexicon[1..-1] ]
end

as alternative, see Marshal class:

1) run this program one time:
..... # your code for reading lexicon from text file
File.open("posterity", "w+") do |f|
  Marshal.dump(lexicon, f)
end

2) use this code to restore lexicon:
lexicon = ''
File.open("posterity") do |f|  
  lexicon = Marshal.load(f)
end  
..... # using lexicon
