### Collaboration Problem

Part 1: Read the collaboration policy; print out and sign a copy. This is the only paper handin you'll do all semester.

Part 2: Describe, in your own words, the collaboration policy. This should be just a few quick sentences that make it clear that you understand it.

Part 3: Here are three scenarios. For each one, describe whether anyone violated the collaboration policy, and if so, who violated it and how.

• (a) Xan and Robin are working on a homework problem together --- one that's marked as "collaborative" rather than "independent". Xan tells Robin that it's easy to do part "c": you just use the built-in spreadsheet function "ROUND", by writing "=Round(A5, 0)". Robin says, "...and that'll round off the value in cell A5?" and Xan says it will. Robin asks, "What's the 0 in there for?" Xan says, "Don't worry about it... it's just something you have to put in to make rounding work." So, Robin types "=Round(A5, 0)", gets the correct answer and hands it in.
• (b) Anu and Martine are roommates, and both are taking CS0030. Anu uses a laptop (with a login and password) for everything, including 0030 homework. One day, when Anu is out of the room, Martine notices that the laptop is open on Anu's desk, sits down, plugs in a flash drive, and copies Anu's homework onto the drive. Martine then submits several of Anu's solutions without any attribution.
• (c) Eddie and Bill work together on problem 2, which is collaborative, and hand in almost identical answers. Eddie's handin says "Bill and I worked on this together." Bill's handin doesn't mention Eddie. Each of them, when quizzed on the solution, can explain it completely, and the solution is correct.

• Save your answers to Google Document named 'FirstLast_HW0' where 'FirstLast' should be replaced with your first and last names. Share it with cs0030handin@gmail.com
