๐ Topic Summary
Array sorting is a fundamental concept in computer science, crucial for organizing data efficiently. In Java, various sorting algorithms exist, each with its own strengths and weaknesses. These algorithms rearrange the elements of an array into a specific order, such as ascending or descending. Understanding how these algorithms work and their relative performance is key for AP Computer Science A students.
This worksheet will test your knowledge of common sorting algorithms like bubble sort, selection sort, and insertion sort, focusing on their implementation and time complexity. You'll explore core vocabulary, fill in the blanks to solidify your understanding, and engage in critical thinking to apply your knowledge to real-world scenarios.
๐ง Part A: Vocabulary
Match the term with its correct definition:
| Term |
Definition |
| 1. Bubble Sort |
A. A sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. |
| 2. Selection Sort |
B. A sorting algorithm that repeatedly finds the minimum element from the unsorted part and puts it at the beginning. |
| 3. Insertion Sort |
C. A simple sorting algorithm that builds the final sorted array one item at a time. |
| 4. Time Complexity |
D. A measure of the amount of time taken by an algorithm to run as a function of the input size. |
| 5. In-place Sorting |
E. A sorting algorithm that does not require extra space and sorts the array by modifying the array itself. |
Match the correct terms and definitions:
- ๐ Bubble Sort: A
- ๐ Selection Sort: B
- โ๏ธ Insertion Sort: C
- โฑ๏ธ Time Complexity: D
