Re^2: while loop almost correct

[JadeNB]

Hashes are good for this sort of work, the question number is the hash key and the answer is the hash value related to that key

Any time you find yourself thinking of using a number as a key into a hash, you should probably think about whether you mean to be using an array instead. In this case (but not every case: a sparse array is better implemented as a hash, if I'm not mistaken), I think that the answer would be ‘yes’.
