Explained Bubble Sort very quickly

Bubble sort is a simple sorting algorithm that repeatedly steps through a list of elements, compares adjacent items, and swaps them if they are in the wrong order. It gets its name because smaller elements "bubble" to the top of the list while larger elements "sink" to the bottom.


Here's a quick explanation of how bubble sort works:


1. Start at the beginning of the list.

2. Compare the first two elements. If the first element is larger than the second, swap them.

3. Move to the next pair of elements (the second and third elements) and repeat the comparison and swap if necessary.

4. Continue this process, moving through the list one pair at a time, until you reach the end of the list.

5. By the end of the first pass, the largest element will have "bubbled" to the end of the list.

6. Repeat the process for the remaining elements in the list, excluding the last one since it is already in its correct position.

7. Continue this process until the entire list is sorted.


Bubble sort is straightforward to understand and implement, but it's not the most efficient sorting algorithm, especially for large lists. Its time complexity is O(n^2) in the worst and average cases, where "n" is the number of elements in the list. For larger datasets, more efficient sorting algorithms like quicksort or mergesort are typically preferred.
