Question
If the array had been sorted in descending order initially, how many swaps would the Bubble Sort perform?*0/1A. 10B. 15C. 20D. 25 Correct answerA. 10
Solution
To determine the number of swaps that the Bubble Sort would perform if the array had been sorted in descending order initially, we can follow these steps:
- Initialize a counter variable to keep track of the number of swaps.
- Start iterating through the array from the first element to the second-to-last element.
- For each iteration, compare the current element with the next element.
- If the current element is greater than the next element, swap them and increment the counter variable.
- Continue iterating through the array until reaching the end.
- Repeat steps 2-5 until no more swaps are made during an iteration.
- The final value of the counter variable will be the total number of swaps performed.
In this case, since the array is already sorted in descending order, no swaps will be made during the iterations. Therefore, the correct answer is A. 10.

1 pointHow does Bubble Sort compare elements in an array? Compares adjacent elements and swaps if they are in the wrong order Compares random elements in the array Compares all elements with the first element Compares elements in reverse order
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.
