Problem Description:
In England the currency are made up of pound,, and Pence, p, and there are eight coins at general circulation:
1p, 2p, 5p, 10p, 20p, 50p, 1 (100p) and 2 (200p).
It is possible to make 2 in the following way:
One + 150p + 220p + 15p + 12p + 31p
How many different ways can 2 is made using any number of coins?
