Howdy,

New to Ruby and looking for some help.  
I would like to prompt the user for input String of single [0 - 9 incl]  
digits e.g 57  
and convert these to word format and store as a single string e.g  
fiveseven

What way is best to go about doing this.

Should I create a hash of {1 =\> “one”…} and then iterate through the  
input, swapping digits that match a key with the key’s value.

Thanks a lot

I’d rather use an array than a hash in this case:
