Decode the decimal sum:

           T H I S
     +       I S A
     +   G R E A T
     +     T I M E
       -----------
       W A S T E R

Same letter, same digit; different letters, different digits.

Well, that solution validates my spreadsheet algorithm, I know I can generalise it.

The only problem is that I have to do manually what Charlie's program does automatically :-(
