Study Notes
CSC 1061 Data Structures: Bag (Static Array)
- Course content focuses on designing and implementing collection classes using partially filled arrays to store elements.
- Accurate class invariants are crucial for successful implementation.
- Algorithm analysis, including Big O notation, is vital for understanding efficiency.
Objectives
- Design and implement classes that use partially filled arrays for element storage.
- Accurately write and maintain invariants for each implemented class.
- Grasp why algorithm analysis is essential to understanding efficiency.
- Master Big O notation and other relevant techniques of algorithm analysis.
Static Arrays
- Static arrays are compiler-managed arrays, not related to C++ class-level static variables.
- Stored in the stack section of memory.
- Maintain a consistent data type for all elements.
- Fixed size at compile time, immutable during runtime.
- Array indices are 0-based.
- Array declarations determine fixed size (not a zero-based count).
Agenda (Week 4)
- Arrays, Data Structures/Collections, Big-O Analysis.
- Bag Data Structure, Bag Algorithm Efficiency.
- Invariant, Bag ADT.
Array Challenge
- Complete questions 1 and 2 of the array challenge provided, skipping question 3.
- The challenge only relates to arrays and does not involve C++.
Data Structures Overview
- Data structures provide efficient storage and organization of data.
- This course will cover static arrays, dynamic arrays, linked lists, stacks, queues, graphs, binary trees, heaps, and B-trees.
Collections
- Read tutorials and complete activities related to collections and arrays.
- Skip activities related to 1.10.2 Vectors as these will be covered later.
Algorithm Analysis
- Read and complete activities from the tutorial covering algorithm analysis, excluding activities related to 2.2.1.
