Re^2: suppress the elements that appear more than one time in a list

Thanks a lot FunkyMonk

I have tried your method.

However, I did not understand the line :$Hash{$k} += $v;
I replaced with line :$Hash{$v} = $k;
because I would like o have a unique list of the letters (not the numbers)

It would perhaps be better from a maintenance point of view to leave the line `$Hash{$k} += $v;` [download] as it is and change the `split` to reflect the fact that your value comes before the key on the line `my ($v, $k) = split /;/;` [download] You still need to use `+=` since you wish to accumulate the values.
