Everybody at a company is assigned a unique 9 digit ID. How many unique IDs exist?
Brut [27]
If you include all zeroes, then it should be 1,000,000,000. Otherwise it’s 999,999,999.

Write a regular expression of the language havingstrings that either start or end with "00" and have nomore zeroes. Where the al
Brut [27]

Answer:

001*|1*00

Explanation:

The language consists of strings in {0,1} that either start with 00 or end with 00 and have no more zeros.

The requirement can be divided into two parts:

1) Strings that start with 00 and have no more zeros

2) Strings that end with 00 and have no more zeros

Generating regular expressions for these parts:

1) 001*  - starts with two zeros and can have zero or more 1s later

2)1*00  - starts with zero or more 1s and ends with two zeros

So on combining with the or operator(|), the overall regular expression for the strings in the language becomes:

001*|1*00

   service1_cost = 35

elif service1 == "Tire rotation":

   service1_cost = 19

elif service1 == "Car wash":

   service1_cost = 7

elif service1 == "Car wax":

   service1_cost = 12

elif service1 == "-":

   service1 = "No service"

   service1_cost = 0

if service2 == "Oil change":

   service2_cost = 35

elif service2 == "Tire rotation":

   service2_cost = 19

elif service2 == "Car wash":

   service2_cost = 7

elif service2 == "Car wax":

   service2_cost = 12

elif service2 == "-":

   service2 = "No service"

   service2_cost = 0

print("- - -")

print("Davy's auto shop invoice")

print("Service 1: " + service1 + " costs $" + str(service1_cost))

print("Service 2: " + service2)

print("Total: $" + str(service1_cost + service2_cost))

Explanation:

- Initialize the variables for cost values

- Ask the user for the services

- Depending on the user choice, calculate the cost of each service using if else structure

- Print the chosen services, cost of each service and total cost
