6.1 Bubble Sort
Let's start with the Bubble Sort algorithm. Bubble Sort is one of the simplest sorting algorithms that can be easily understood by beginners. It is a good starting point for understanding the logic behind sorting and serves as a foundation for learning more complex algorithms.
Bubble Sort works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items, and swapping them if they are in the wrong order. The algorithm sorts the list by moving the larger or smaller elements towards the end or beginning of the list, respectively. This process is repeated until the list is sorted in ascending or descending order.
Although Bubble Sort is simple, it has some limitations. In terms of time complexity, Bubble Sort is not the most efficient algorithm. It has an average and worst-case complexity of O(n²), where n is the number of items to be sorted. This means that as the size of the input grows, the algorithm takes longer to execute,...
