Is there a simple way to see if an element exists in a list? Right now I use this code which seems cumbersome:
sub IsItem {
# usage: IsItem(item to find, pointer to list to search)
my $ref = @_[1];
foreach my $e (@{$ref}) {
if (@_[0] eq $e) {return 1}
}
return 0;
}
my @a = (10,20,30);
print 'IsItem=',IsItem(20,\@a);
print 'IsItem=',IsItem(5,\@a);
