Sorting Algorithms Overview

What is the main purpose of sorting algorithms?

What are the two main types of sorting algorithms?

Which of these is NOT a type of internal sorting algorithm?

Selection Sort is generally considered a very efficient sorting algorithm.

What is the main advantage of using the Bubble Sort algorithm?

Quick Sort is a recursive sorting algorithm that utilizes the divide and conquer strategy.

What is the primary purpose of the Swap function in sorting algorithms?

The efficiency of a sorting algorithm is often measured by its ______ complexity.

Selection Sort and Bubble Sort have the same time complexity.

Sorting Algorithms

Sorting algorithms organize elements in ascending or descending order.
Data to be sorted needs a defined order relationship.
Algorithm selection depends on the data's characteristics and drawbacks.

Types of Sorting

Internal Sort: Algorithm operates within memory. Ideal for manageable data volumes.
- Selection Sort: Finds the smallest (or largest) element and swaps it to the correct position.
- Bubble Sort: Compares adjacent elements, swapping if order is incorrect. Iterates until no swaps occur.
- Insertion Sort: Inserts each element into its correct position within the sorted portion.
- Shell Sort: Improves insertion sort by comparing elements that are spaced apart.
External Sort: Algorithm handles data too large for memory. This relies on secondary storage.
- Merge Sort: Repeatedly divides the data in half until small enough to be sorted in memory, then merges sorted sub-sections.
- Balanced two-way Merge Sort: Improved merge sort for optimal merging.
- Divided and Conquer Merge Sort: A methodology for merge sort.

Swap Operations

Swap: Exchanging the values of two variables. Crucial in many sorting algorithms.
Methods:
- Using a temporary variable.
- Using arithmetic operations (only for numerical values; can lead to overflow).
- Using bitwise XOR operator (efficient, no intermediate variable, no overflow).

Time Complexity (Big-O)

Selection Sort: O(n^2)
Bubble Sort: O(n^2)
Merge Sort: O(n log n)
