## What is an example of bubble sort?

Bubble sort starts with very first two elements, comparing them to check which one is greater. ( 5 1 4 2 8 ) –> ( 1 5 4 2 8 ), Here, algorithm compares the first two elements, and swaps since 5 > 1. ( 1 4 2 5 8 ) –> ( 1 4 2 5 8 ), Now, since these elements are already in order (8 > 5), algorithm does not swap them.

**What is bubble sort in C with example?**

Bubble sort in C is a straightforward sorting algorithm that checks and swaps elements if they are not in the intended order. It compares two adjacent elements to find which one is greater or lesser and switches them based on the given condition until the final place of the element is found.

### What is I and J in bubble sort?

Bubble Sort Program in C We loop n times – once for each element of the array. When i = 0, with the j loop, the largest element of the array reaches its correct position. When i = 1, with the j loop, the second largest element of the array reaches its correct position.

**How do you make a bubble sort adaptive?**

The trick is to keep a flag that tracks whether we swapped any element in the last iteration. If no elements were swapped, that means the array has already been sorted – so we can just stop the iterations early. This little trick makes Bubble Sort an adaptive sorting algorithm.

## What are the number of Swappings needed to sort the numbers 4 9 8 2 1 in ascending order using bubble sort?

Total 18 swapping required to get the bubble sort.

**Where is bubble sort used?**

Bubble sort is mainly used in educational purposes for helping students understand the foundations of sorting. This is used to identify whether the list is already sorted. When the list is already sorted (which is the best-case scenario), the complexity of bubble sort is only O(n) .

### Is Selectionsort stable?

NoSelection sort / Stable

**Is Mergesort adaptive?**

Merge Sort is a comparison based sorting algorithm with O(n log n) computational complexity. It is not adaptive to existence of ordering among the elements. Thus, has the same computational complexity in any case.

## Is Bubblesort adaptive?

Bubble sort is adaptive. It means that for almost sorted array it gives O(n) estimation. Avoid implementations, which don’t check if the array is already sorted on every step (any swaps made).

**When bubble sort ascending order is applied on array A 178 95 65 99 24 how many swaps are done before element 95 is placed at its correct position?**

Therefore, number of swaps is 6.
