Draw a use case diagram based on the system description below using VISIO.

Homework assignment distribution & collection is an integral part of any educational system. Today, this task is performed manually. What we want the homework assignment distribution and collection system (HACS for short) to do is to automate this process. HACS will be used by instructors to distribute homework assignments, review students solutions, distribute suggested solutions, and distribute student grades. HACS will also allow students to submit their solutions and to receive notifications when new assignments are posted. Lastly, HACS will send reminders to students when assignments are almost due, and another reminders when assignments are overdue.

Please come up with and include at least one include and one extend relationships in your diagram (based on your general understanding of the homework assignment distribution and collection system and what might be useful). In addition, create at least two additional use cases that might be important for this system.
