可以通过以下方式使to 2.50:
1×£1 + 2×50p + 2×20p + 1×5p + 1×2p + 3×1p
写一个程序,计算出使用任意数量的硬币可以制作of 2.50的所有不同方法。
下面有没有更简单的方法来完成这一切呢?
coins = [100,50,20,10,5,2,1]
number_of_coins = int(input("How many coins do you have: "))
num_of_ways = []
for i in range(3):
for j in range(6):
for k in

SELECT name, date, time, location
FROM
(SELECT * FROM table1
UNION ALL
SELECT * FROM table2) data
GROUP BY name, date, time, location
HAVING count(*)!=2
现在,我希望能够比较table1和table2,但是现在table2有了另一个名为origin的专栏,我不确定如何扩展我当前的逻辑来实现它。
