See the Requirement Guidelines for In-Class Exercise (ICE) assignments.

This is an in-class group assignment. Print the names and VT email PIDs of the group members in the space provided so that each group member knows who is in the group. Submit one copy of this to your instructor before you leave class.

Group member name Role VT Email PID@vt.edu

Identify the role taken by each group member in the table above.

Follow the Solver/Listener paradigm to analyze and attempt to solve the given problem. It is important that you manage the discussions in a disciplined manner so that the scribe can record adequate notes to prepare a transcript of your session.

When you believe you have a solution to the problem, work together to prepare a written report for submission.

After the class, and by the announced deadline, complete the written report of your session, including the interactions between the solver and the listeners and a detailed explanation of how you arrived at your solution. You may include diagrams and mathematical work if you used those as part of your process.

Only one group member, the coordinator, must submit to Canvas via the collection point for Hw03-ICE01. The team must ensure that their group partners names and email PIDs are at the top of the first page of the submission.

Remember that the evaluation of your solution will depend primarily on the completeness and clarity of your explanation.
