competition winner!

Many thanks to all of you who entered our brainbuster no. 25.

We had a large number of entries, mostly giving the correct answer - although as usual several people neglected to check if their answer actually worked!

Most entrants found the answer by analysis but a few wrote a 'brute force' computer program to solve it.

A detailed answer was given by our lucky winner drawn from the ECM mug, Lawrence Taylor.

Lawrence wins the voucher to spend on his choice of high tech gadgets, games & gifts.

You can now view the solution by clicking on the brainbuster no. 25 menu item opposite.
