In this video, we will learn about B2.4.3: Bubble Sort and Selection Sort.

Sorting algorithms are used to arrange data into a specific order, such as ascending or descending order. Two common sorting algorithms are bubble sort and selection sort.

This lesson explains how to construct and trace algorithms for bubble sort and selection sort. You will learn how bubble sort repeatedly compares and swaps adjacent values, while selection sort repeatedly finds the smallest or largest value and places it in the correct position.

We will also evaluate the time complexity and space complexity of each algorithm using Big O notation. This helps us understand how efficient each sorting method is when working with different sizes of data.

By the end of this video, you should be able to construct and trace bubble sort and selection sort algorithms, compare their advantages and disadvantages, and explain their efficiency across different data sets.
