Python Coin change SO CLOSE

Question

I am doing the coin-change problem. I have finished the problem in that it prints out how many coins I need to make the least amount of change possible, but how do I change

Answer 1

A different version of your program:

def change(C, V, res=None):
    res = [] if res is None else res
    if len(V) == 0:
        return len(res), res
    maxx = max(V)
    V.remove(maxx)
    ans = C//maxx
    if ans == 0 and maxx < C :
        res += [maxx] * ans
        return len(res), res
    else:
        res += [maxx] * ans
        return  change(C % maxx, V, res)

print change(48,[1, 5, 10, 25, 50])
print change(30,[25, 10, 2, 3, 1])

output:

(6, [25, 10, 10, 1, 1, 1])
(3, [25, 3, 2])

PS: I'll add an explanation if you want.
