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. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller or larger elements "bubble" to the top of the list.
How Bubble Sort Works
Bubble Sort works by comparing adjacent elements in an array and swapping them if they are in the wrong order. The algorithm starts at the beginning of the array and compares the first two elements. If the first element is greater than the second element, the two elements are swapped. The algorithm then moves to the next pair of elements and repeats the process until it reaches the end of the array.
Once the end of the array is reached, the algorithm starts again from the beginning and repeats the process until no more swaps are needed. At this point, the array is sorted.
Advantages and Disadvantages of Bubble Sort
One advantage of Bubble Sort is that it is easy to understand and implement. It is also a stable sort, meaning that it preserves the relative order of equal elements in the sorted array.
However, Bubble Sort has a time complexity of O(n^2), which means that it is not efficient for large arrays. It also has a space complexity of O(1), which means that it sorts the array in place and does not require additional memory.
