Hello monks!
If you have the following AoA:
 @AoA = (
           [ "X", "Z", "W", "X", "Z", "Z" ],
           [ "Z", "Z", "X", "X", "X", "W" ],
           [ "X", "Z", "X", "W", "W", "W" ],
           [ "Z", "X", "W", "X", "Z", "Z" ],
           [ "Z", "X", "W", "X", "X", "W" ],
           [ "Z", "X", "X", "X", "Z", "W" ],
    );

is there a way to traverse this AoA by column? I want to calculate the number of occurences for each letter (X, W and Z) in the respective column, and, if there are more than 60% of one letter in a column, the the final combined array will hold this letter. If we have a tie, or les than 60%, we would use another letter, say A
In particular, the combined array that would come up from this AoA would be:
[ "Z", "A", "A", "X", "Z", "W" ]
