Why is bubble sort not efficient?

Can you explain why bubble sort is considered inefficient?

Bubble sort is inefficient because it has a time complexity of O(n^2), making it slow for large datasets.

What does O(n^2) mean in terms of performance?

O(n^2) means that the time it takes to sort the data increases quadratically as the number of items increases.

Are there better sorting algorithms I should know about?

Yes, algorithms like quicksort and mergesort have better average time complexities, typically O(n log n).

Why is quicksort faster than bubble sort?

Quicksort is faster because it uses a divide-and-conquer approach, reducing the number of comparisons needed.
