in reply to What would be the easier way

Use a hash table with an array ref for each entry, doing something like push @{ $height{$input} }, $value; after parsing each line into $input and $value; leaving you with something like this:

%height = (
  'house' => [
               string1,
               string2
             ],
  'table' => [
               string3,
               string4
             ]
)

and @{$height{house}} would be all the values for house in an array

    hey, im sorry i didnt really get that since ive started using perl recently, can you explain this part to me a little @{ $height{$input}} What will my array be called then? Thanks!

      @{ $whatever } de-references the array ref $whatever so you can use the reference as an array. Your data are contained in array references which you need to de-reference with @{ } to use as arrays.

        That is not an array, but an array reference.
