How does bubble sort work?

Can you explain how bubble sort works?

Sure! 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.

Can you visualize how bubble sort sorts an array?

Absolutely! Imagine an array of numbers. The algorithm starts at the beginning and compares the first two elements. If the first is greater than the second, they swap. This process continues until the largest element 'bubbles' to the end of the array.

What happens in each pass of the bubble sort?

In each pass, the algorithm compares adjacent elements and swaps them if needed. After each complete pass, the next largest element is in its correct position.

How efficient is bubble sort compared to other sorting algorithms?

Bubble sort is not very efficient for large datasets. Its average and worst-case time complexity is O(n^2), making it slower than algorithms like quicksort or mergesort.
