I need help with modifying this short Python program:

amount_to_change = 19 num_fives = amount_to_change // 5

num_ones = amount_to_change % 5

print('Change for $', amount_to_change) print(num_fives, 'five dollar bill(s) and', num_ones, 'one dollar bill(s)')

4. Change the assignment statement (amount_to_change = 19) to an input statement with a prompt.

5. Insert statements to calculate the number of twenties and tens (before the number of fives is calculated).

6. Insert statements to print the number of twenties and tens (on a separate line, before the numbers of fives and ones are printed).
