Question
To sort a list in ascending order when does Bubble Sort exhibit poor performance? When the list is sorted in ascending order When the list is sorted in descending order When the list contains unique elements Bubble Sort always exhibits poor performance
Solution
Bubble Sort exhibits poor performance when the list is sorted in descending order. This is because Bubble Sort compares each pair of adjacent items and swaps them if they are in the wrong order. So, if the list is already sorted in descending order, Bubble Sort would need to make the maximum number of comparisons and swaps, leading to poor performance.
However, it's important to note that Bubble Sort generally has poor performance compared to other sorting algorithms, regardless of the initial order of the list. This is due to its high time complexity of O(n^2) in both average and worst-case scenarios.

Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order. The problem with bubble sort is its worst case scenario. When the smallest element is in the last position, then it takes more time to sort in ascending order, but takes less time to sort in descending order.An array is called beautiful if all the elements of the array are in either ascending or descending order. Given an array of numbers, find the minimum swap operations required to make the array beautiful.
