Understanding Bubble Sort
Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. This process repeats until the list is sorted.
Steps of Bubble Sort:
- Start with the first element and compare it to the second. If the first is greater than the second, swap them.
- Move to the next pair (second and third element) and compare them. Swap them if necessary.
- Continue this until the end of the list. This completes one whole pass.
- Repeat the steps until no swaps are needed in a whole pass.
This algorithm gets its name because smaller elements "bubble" to the top of the list.
Advantages and Disadvantages
Bubble Sort is easy to implement but less efficient on large lists compared to advanced algorithms such as quicksort, heapsort, or merge sort. However, it is useful for small datasets or when teaching the basics of sorting algorithms.
