Can anyone suggest if using multi dimensional arrays would be a good idea?

Question

To represent the number of used letters by each player at each hand and the remaining total number of letters would using a multi-dimensional array be useful?

Answer 1

Yes of course but, if you are not doing any type of modifications to the elements, it may even be better to use tuples instead of arrays/lists. See, tuples are faster and require less bytes to store because they are supposed to be immutable.
