Broken Examples that were used to test your test cases.
Test Cases that were used to test your implementation.
If your debugging techniques are limited to using System.out.print() statements, then you are not using
the tools available in Eclipse. Make sure that you know how to use the debugger - it will save you a lot of time
when writing code.
Academic Email Etiquette:
- Check the school email address on a regular basis. You can simply forward its content
to another email account that you use regularly.
- Use your school's email account to send emails to professors, instructors, TA's, graders,
administrators, etc. OR make sure that your email address contains your true name,
not "firstname.lastname@example.org", "BabyGurl@yahoo.com" or some other cool alias.
- Start your email with proper salutations! Use the correct titles (Professor, Dr., etc.)
and spell first and last names correctly. If you are on the first name basis with your instructors,
use their names, not "Hey". For example: "Dear Professor Drummer" or "Dear Robert", not "Hey Bob".
- Sign your name under the body of your email, otherwise you expect people to read emails from anonymous.
- Do not write everything in upper-case letters. Do not write everything in lower-case letters.
- Make sure you included everything you wanted before hitting send. Don't send three emails
one after another because you forgot something in the first one.
- Proofread the text in your email before sending it. Most of the email clients check for
typos, but they cannot tell if your email makes much sense. Read it, before you send it.

Assignment submission protocol:
- Develop the code on your own machine or a lab machine. Make sure you compile and test things as you are working on the code.
- Use SFTP client to transfer all the code to the i5.nyu.edu machine (it does not matter which exact application for file transfer you use as long as the files get there).
- Login to i5.nyu.edu using ssh (again, it does not matter which ssh client you use).
- Comiple the code on the i5.nyu.edu machine. Repeat all your tests on that machine.
- If either the compilation or any of your tests fail, go back, fix the code and then repeat this step again.
- On your own machine or a lab machine, create a zip file with all your latest code (make sure that you update the code with any fixes/changes that you made after running the code on i5.nyu.edu).
- Upload the zip file to NYU Classes.
A few things you should know from before:
Testing = hacking the code
The following source code files contain an implementation of the linked list (unsorted list of doubles
that is implemented iteratively). You can easily write test cases to make the first version fail. The second version
solves some of the problems of the first version, but not all.
