Coin sums
Problem 31
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?
使用动态规划方法
def coinSum():
#目标200
target = 200
coinList = [1,2,5,10,20,50,100,200]
#准备记录过程中的所有线路数量
resultList=[0] * (target+1)
#第零个是1
resultList[0]=1
for i in range(0,len(coinList)):
#测试每一个类型
for j in range(coinList[i],target+1):
#最新的线路数量,更新
resultList[j] += resultList[j - coinList[i]]
return resultList[200]
print(coinSum())
本文通过动态规划方法解决硬币组合问题,详细解释了如何使用动态规划来求解给定货币面额下的不同组合方式,以实现2英镑的多种构成方式。
