一个应聘的试题 PHP 谁给解答一下 急用

=head1 *NAME*

perltst5.prl -- language analyzer (perl test 5)

=head1 *DESCRIPTION*

This program analyzes an arbitrary sample of any language written in
latin characters (a-z).

=head1 *TASK*

The program should output the following information:

1. Frequency distribution of the vowels and consonants used in the sample.

2. A list of the different consonant-vowel patterns
  used in the sample:
  A consonant-vowel pattern ("c-w pattern") should have
  an 'a' for each vowel, and a 'c' for each consonant;
  e.g. the c-w pattern word 'mopufom' would be 'cacacac',
  and the c-w pattern for 'oleq' would be 'acac'.

3. The most frequent consonant-vowel pattern in the sample.


=head1 *QUESTION*

The sample below consists of two *different* language samples,
pasted one after another.

At which point does the second one probably start?

# Note: qw( ) "quotes words": creates an array with the space-separated items

@vowels = qw( a e i o u y );
@cons  = qw( b c d f g h j k l m n p q r s t v w x z );

$/ = undef;
$_ = <DATA>; # All the text is in $_ now.
