I am new to perl having basic idea about the programming and scripting
language, so I am learning Perl through Perl Cookbook, 2nd edition.
on page 118, (receipe 4.4 Implementing Sparse Array), Here is one
statement.
Using a hash representation, you should instead do either this to
process elements in index order:
foreach $element ( @fake_array{ sort {$a <=> $b} keys %fake_array } )
{
# do something with $element
}
Question: I am not able to understand the statement -"@fake_array
{ sort {$a <=> $b} keys %fake_array }".
I understood that we are sorting the keys of a hash %fake_array. But
what is the meaning of @fake_array here???
Appreciate your help to explain me this.
Regards
RP..
