Quizplus · Accepted Answer

Bubble sort, in the worst case, requires approximately $n^2$ comparisons, where $n$ is the number of items to be sorted. This is because each item is compared to every other item through a series of passes. However, the exact number can be less depending on the initial order of the items and optimizations like the flag to stop if no swaps are made.
