Are the elements in the array always in this order, i.e. XXY comes before YYK? If yes, then why don't you just remove the reverse from foreach my $all_item (reverse @{ $all })? Then it works for me.

If the order of the data can change, then what the easiest way to solve it is depends on how big the input data can get - if it's always small, then you can just loop over the data array twice, once to get the value from XXY and once to save it to YYK.
