Due Date: February 7, 2001

(1)    Consider the following dictionary file: words.txt , which contains one word per line.  Write a Perl program or Perl command line statement to list all words that contain all five vowels (in any order) in the following format:

1: adventitious
2: aeronautic
3: ambidextrous
4: argillaceous
5: argumentation
6: auctioneer
7: audiotape
8: augmentation
9: aureomycin
10: authoritative
11: autocollimate
12: automobile
13: automotive
14: autosuggestible
15: beaujolais
...

(2)    Consider the dictionary again.  Write a Perl program to list every word such that if every character of the word is shifted three characters cyclically, it is still a word in the dictionary.  For example, 'box' is in the output because shifting each character of 'box' three characters results in 'era,' another word in the dictionary.  The output format should be:

a => d
al => do
ala => dod
alb => doe
ar => du
ark => dun
az => dc
b => e
be => eh
bob => ere
boo => err
box => era
c => f
cb => fe
cobb => free
cobra => freud
col => fro
cold => frog
...

(3)    Consider the following XML file: news.xml.  Write a Perl program or Perl command statement to print all headline news, one headline per line.  You may assume that headlines are stored in the lines within the XML element headline_text.  Output for using news.xml:
