Policies: All work on project must be done with pairs unless stated otherwise. You are encouraged to discuss with your classmates about the given project, but these discussions should be carried out in an abstract way. That is, discussions related to a particular solution to a specific problem (either in actual code or in the pseudocode) will not be tolerated.

In short, turning in someone else’s work, in whole or in part, as your own will be considered as a violation of academic integrity. The conducted study must be reported in a suitable format and be sent through email.
