Write the function calculate_bills_to_use that returns a dictionary with the bill denomination and how many bills to use. Examples:
>>> calculate_bills_to_use(843)
{500: 1, 100: 3, 50: 0, 25: 1, 10: 1, 5: 1, 1: 3}
>>> calculate_bills_to_use(1763)
{500: 3, 100: 2, 50: 1, 25: 0, 10: 1, 5: 0, 1: 3}
>>> calculate_bills_to_use(177)
{500: 0, 100: 1, 50: 1, 25: 1, 10: 0, 5: 0, 1: 2}
>>> calculate_bills_to_use(355)
{500: 0, 100: 3, 50: 1, 25: 0, 10: 0, 5: 1, 1: 0}
>>> calculate_bills_to_use(10_988)
{500: 21, 100: 4, 50: 1, 25: 1, 10: 1, 5: 0, 1: 3}
Write the function calculate_bills_to_use_advanced that receives two parameters: the amount to withdraw, and a dictionary with bills and their availability. For example:
# There are no $100 bills
>>> calculate_bills_to_use_advanced(163, {
500: 1,
100: 0,
50: 10,
25: 10,
10: 10,
5: 10,
1: 10
})
{500: 0, 100: 0, 50: 3.0, 25: 0, 10: 1.0, 5: 0, 1: 3.0}
# There are no $100 or $10 bills
>>> calculate_bills_to_use_advanced(163, {
500: 1,
100: 0,
50: 10,
25: 10,
10: 0,
5: 10,
1: 10
})
{500: 0, 100: 0, 50: 3.0, 25: 0, 10: 0, 5: 2.0, 1: 3.0}
