Study Notes
Arrays
- Drawback: Fixed size limit; requires predefined capacity which may lead to wasted space or insufficient storage.
- Time-consuming insertions and deletions at interior positions: Involves shifting elements to maintain order, making it inefficient.
Singly Linked Lists
- Consist of nodes linked sequentially, where each node points to the next.
- Each node stores:
- Data or value
- Reference to the next node in the sequence.
Comparisons and Alternatives
- Alternative to an array-based structure: Singly linked lists offer dynamic size and easier modifications.
- Drawback of singly linked lists: Increased memory usage due to storage of pointers, leading to overhead.
- Benefit over arrays: Easier and more efficient frequent insertions and deletions at interior positions without shifting elements.
Array Capacity
- Array capacity must be determined at creation; it limits flexibility since it cannot change dynamically based on data needs.

Description
Test your knowledge of Java data structures and algorithms with this quiz based on the book "Data Structures and Algorithms in Java, 6th edition" by Goodrich, Tamassia, and Goldwasser. This quiz specifically focuses on singly linked lists and arrays, two fundamental concepts in data structure implementation.
