Please help.UML activity Diagrams are a tool for modeling processes. Much of software development consists of processes: algorithms, software lifecycles, development processes, application flow, business processes, etc. Thus activity diagrams are useful for a wide range of applications.

1. Draw an activity diagram describing how two people would peel a pot of potatoes.

2. Draw an activity diagram describing an algorithm for finding the maximum value in a list. The input is the list, and output is the maximum value.

3. Draw an activity diagram describing the flow of Canvas login using Duo. Make sure to include some error conditions (e.g., incorrect password, Duo timeout).
