simply loop through the list or array you have and see if you can find what
you are looking for:
my @i = ( 1..100 );
my $found = 0;
#-- looking for 34
foreach my $j (@i){
#-- exit as soon as possible
$found = 1, last if($j == 34);
}
print $found ? "found 34\n" : "34 not found\n";
or use a hash for faster loop up:
my %h;
my @i = ( 1..100);
@h{@i} = ();
if(exists $h{34}){
print "found 34\n";
}else{
print "34 not found\n";
}
don't use hash if:
1. @i has duplicate value which you want to keep
2. order is important
3. @i is huge and takes up a lot of memory
