Related to my previous question (found here), I want to be able to implement the answers given with a 2 dimensional array, instead of one dimensional.
Reference Array
row[1][0]: 13, row[1][1]: Sony
row[0][0]: 19, r开发者_JAVA技巧ow[0][1]: Canon
row[2][0]: 25, row[2][1]: HP
Search String: Sony's Cyber-shot DSC-S600
End Result: 13
use strict;
use warnings;
my @array = (
[ 19, 'Canon' ],
[ 13, 'Sony' ],
[ 25, 'HP' ],
);
my $searchString = "Sony's Cyber-shot DSC-S600";
my @result = map { $array[$_][0] } # Get the 0th column...
grep { $searchString =~ /$array[$_][1]/ } # ... of rows where the
0 .. $#array; # first row matches
print "@result"; # prints '13'
The beauty of this approach is that it deals with the possibility of multiple matches, so if Sony and HP ever decided to collaborate on a camera, your code can return both! (13 25
