Given that the concatenation ABCDE digits is a 9-digit zero-less pandigital number
and so is the sum S - there is only one sum S to make the above equation true.

I've participated in some programming competitions where you are given a single problem and it is a race to see who can get the right answer first. The strategy I often deploy is to get a programming running as soon as I can that I know will solve it, then while it is running try and improve it and run those in parallel, in a sense ending up with my programs racing against each other.
Often times the case is that my first one finishes before my most optimal one does, as it took me too long to discover/code the more optimal solution. Which goes to show it is often best to start with a working solution than to wait for an optimal one :-)
