Department Notes:

Course objectives: Students who take CS 47B are expected to have had a course that familiarized them with the following: Arrays and linked structures, in particular with the efficiency tradeoffs between them; a variety of sorting algorithms for arrays and linked lists, including some 0(n log n) sorts; binary search trees; and stacks and queues.

Topics Covered: Course activities include programming assignments and quizzes; quizzes focus on low-level language details or programming techniques, while programming assignments are broader in scope. One of the programs is a substantial project comprising several hundred lines of code. The list of programming assignments appears below. All assignments use the Java programming language.

  • Iterator exercises: Students write a breadth-first and a depth-first iterator for a general tree.
  • Hashing exercises: Students analyze and devise hash functions applied to particular sets of data.
  • Blocks project: This project involves solving a sliding-block puzzle. Input data are an initial configuration and a goal configuration; the solution program must find a sequence of block moves that lead from the initial configuration to the goal. The project has a number of interesting features: it's an example of backtracking search in which a hash table is used to avoid cycling; not only execution time, but also memory use must be accounted for in data structure and algorithm design.
  • Heap exercises: Students work with code to manage a binary heap.
  • Storage management exercises: Students modify a simulated storage manager, changing its first-fit strategy to best-fit and evaluating the result.
