Problem 31：Coin sums
In England the currency is made up of pound, £, and pence, p, and there are eight coins in general circulation:1p, 2p, 5p, 10p, 20p, 50p, £1 (100p) and £2 (200p).
It is possible to make £2 in the following way:1×£1 + 1×50p + 2×20p + 1×5p + 1×2p + 3×1p
How many different ways can £2 be made using any number of coins?
- 解答例
way = [0] * 201 way[0] = 1 coin = [1, 2, 5, 10, 20, 50, 100, 200] for c in coin: for w in range(c, 201): way[w] += way[w - c] print(way[200])
