I need help writing a C language program that assigns retail workers to customer orders in a time-efficient manner. The requirements are:

1. Assume 2 categories of items for sale (books, electronics), each order has 10 items at most, and there are 5 initially available workers (Alice, Bob, Carol, Dave, Emma)

2. Each worker can be assigned to more than one customer order (bundling the orders) if all items in the orders are in the same category, but the total number of items can not exceed 10. For instance, if the items are all books and no more than 10 books in multiple orders, they may be bundled. The system should not read in the entire input file before processing orders.

3. If a worker has capacity to bundle, he or she waits to potentially bundle orders, but should not wait for more than 5 minutes.

4. only consecutive orders can be bundled; ie. older orders before newer ones.

5. Assume each worker needs 1 minute to find and pick each item in the same category and an additional 5 minutes of traveling time for each category.

6. Three singly linked lists must be used to manage customer orders, available workers, and worker assignments separately.

7. An input file containing customer orders will be used to simulate the customer orders. The input file is taken as a command-line argument and the output is printed to the screen.

Each input line is one of the following:

CustomerOrder orderTime customer numberOfBooks numberOfElectronics

PrintAvailableWorkerList printTime PrintWorkerAssignmentList printTime PrintMaxFulfillmentTime printTime

For simplicity, time is in HHMM format (HH: 00-23 and MM: 00-59), the leading zero is optional. Fulfillment Time is the amount of time between when an order is made and when a worker finishes picking items for the order(s). MaxFulfillmentTime is the longest Fulfillment Time among all the orders so far. AvailableWorkerList is in availability order. Ordering of WorkerAssignmentList is the expected completion time of a worker.

Each output line is one of the following:

CustomerOrder orderTime customer numOfBooks numOfElectronics WorkerAssignment assignmentTime worker customer1 customer2 ... OrderCompletion orderCompletionTime customer

AvailableWorkerList worker1 worker2 ... WorkerAssignmentList worker1:customer1 worker2:customer2a,customer2b ...

MaxFullfillmentTime numberOfMinutes
