I want to get an array which has all the element unified, like (@array=(a,b,c,d,e,f)is OK; if @array=(a,b,c,a)because it already has an 'a' inside the array, I will keep it to @array=(a,b,c);. ....... my code like:
my @array=split('',$_);
my $data=$array[2];
push(@data, $data);

[download]
I have to check if $data is already inside @data before I push it in. What should I do? Thanks!!!
