094. the sorting hat: implementing bubble sort (ks3)
Step into the world of algorithmic sorting. Learn how the bubble sort algorithm works by logically comparing and swapping data into perfect order.
Imagine you have a mixed-up deck of cards and need to put them in perfect numerical order. How would you do it systematically? In this lesson, we will learn our very first sorting algorithm: the Bubble Sort. You will discover how computers use simple logic to compare and swap items over and over again until everything is perfectly organised.
