用100元人民币兑换10元5元和1元的纸币共50张实验步骤

以下是用100元人民币兑换10元、5元和1元纸币共50张的实验步骤：

1. 使用while循环进行兑换：

total_money = 100
count = 0
i = 0
j = 0
k = 0

while total_money >= 10 and count < 50:
    if i < 10:
        i += 1
        total_money -= 10
        count += 1
    elif j < 5:
        j += 1
        total_money -= 5
        count += 1
    elif k < 35:
        k += 1
        total_money -= 1
        count += 1

print("10元纸币数量：", i)
print("5元纸币数量：", j)
print("1元纸币数量：", k)

2. 使用for循环进行兑换：

total_money = 100
count = 0
i = 0
j = 0
k = 0

for i in range(10):
    for j in range(5):
        for k in range(35):
            if total_money >= 10 and count < 50:
                total_money -= 10
                count += 1
            elif total_money >= 5 and count < 50:
                total_money -= 5
                count += 1
            elif total_money >= 1 and count < 50:
                total_money -= 1
                count += 1

print("10元纸币数量：", i)
print("5元纸币数量：", j)
print("1元纸币数量：", k)

3. 使用do-while循环进行兑换（Python中没有原生的do-while循环，可以使用while循环实现）：

total_money = 100
count = 0
i = 0
j = 0
k = 0

while True:
    if total_money >= 10 and count < 50:
        total_money -= 10
        count += 1
        i += 1
    elif total_money >= 5 and count < 50:
        total_money -= 5
        count += 1
        j += 1
    elif total_money >= 1 and count < 50:
        total_money -= 1
        count += 1
        k += 1
    else:
        break

print("10元纸币数量：", i)
print("5元纸币数量：", j)
print("1元纸币数量：", k)
