• 18-sep:
  • Sample task: nested comment reporting, iterative solution, recursive solution
• 25-sep:
  • List abstract data type
  • Array implementation of list adt
  • Linked lists (using only list nodes)
• 1-sep:
  • Linked list class
  • The iterator pattern
  • Generic data structures
  • Running time analysis
• 8-sep:
  • Queues and stacks
  • Java Queue interface and Stack class
  • Implementations of queues and stacks with linked lists
• 15-sep:
  • Recursion
  • Java List collection
  • Recursive versions of insertion sort and selection sort
• 22-sep:
  • Set and map abstract data types: Set and Map interfaces (with two implementations hash map & tree map)
  • Binary search
  • Static sets and maps implementation with binary search
• 6-Oct:
  • Binary search trees
• 13-Oct:
  • Running time analysis/Big-O notation (formal)
  • Balanced binary search trees (AVL trees)
• 3-Nov:
  • Priority queues
  • Binary heap
  • Heap sort

Tasks

• Introduction: Nearby Search, Statuses
• Lists: Zooma 1, Zooma 2, Zooma 3
• Stacks and queues: Job queue, Parentheses, Expressions
  • Java collections:
    • Queues interface Queue<E>, short descriptions and examples
    • Stacks class Stack<E>
• Sorting 1
  • Recursive practice 01204212/recur
  • Sorting tasks: Integer sorting
• Sets and maps: ID Request, Like count, Resistors
• Priority queues: icecream shop 3, icecream shop 4
  • Test data: icecream3, icecream4

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)"

Codes

These are codes that you may or may not need.

• Codes related to Zooma tasks
• Linked lists
• Queues and stacks
