Homework

• Homework 1 (due: Aug-7): Zooma 2
• Homework 2 (due: Aug-16): Job queue 2, Expressions
  • Notes: In this homework, you must use your own implementation of queues and stacks based on our linked list implementation. You can start with stack and queue implementations that use this linked list implementation. Note that a few methods are left out, so you need to write your own version of them.
  • How to submit
    • Send two separate emails, each for one of the problem
    • For each problem, attach all your java files and send me an email with the subject "01204212 homework 2 jobqueue (58xxxxxxxx)" or "01204212 homework 2 expr (58xxxxxxxx)"
• Homework 3 (out: Nov-12, due: Nov-19): Sorting election 2012 results
  • How to submit: send an email to me with all your java files attached. Use "01204212 homework 3 sorting (58xxxxxxxx)" as the subject (replace xxx with your id).
• Homework 4 (out: Nov-24, due: Dec-1): Top scores
  • How to submit: send an email to me with all your java files attached. Use "01204212 homework 4 top scores (58xxxxxxxx)" as the subject (replace xxx with your id).
• Homework 5 (out: Nov-30, due: Dec-4): Web cache
  • You can use any Java collection library (e.g., LinkedList, HashMap, or TreeMap). So don't waste time implementing your own data structures.
  • How to submit: send an email to me with all your java files attached. Use "01204212 homework 5 web cache (58xxxxxxxx)" as the subject
• Homework 6 (out: Dec-5, due: extended to Dec-14 Dec-12): Maze
  • You can use any Java collection library So don't waste time implementing your own data structures.
  • How to submit: send an email to me with all your java files attached. Use "01204212 homework 6 maze (58xxxxxxxx)" as the subject
