Bubble Sort: A Detailed Deep-Dive 🛁

Bubble sort is one of the simplest and least efficient sorting algorithms. It sorts a list by repeatedly stepping through and comparing adjacent elements, swapping them if they're in the wrong order. This process is repeated until the list is sorted. Despite its inefficiency (O(n^2) time complexity in average and worst cases), bubble sort is essential for understanding basic sorting concepts and why more efficient algorithms are preferred. The algorithm's primary merit is its simplicity and ease of implementation.
