Bubble Sort

This lecture introduces the bubble sort algorithm, explaining its concept of comparing and swapping elements in an array to sort them in ascending order. The instructor walks through the process using a sample array, detailing each iteration cycle and the resulting sorted elements. The lecture concludes with a preview of the next session, which will include graphical visualization of the algorithm.

What is the primary concept behind the bubble sort algorithm?

• Merging sorted subarrays

• Dividing the array into two halves

• Comparing and swapping elements

• Using a pivot element for partitioning

In bubble sort, what happens after each cycle?

• The largest unsorted element is moved to the end

• The array is divided into two parts

• The smallest element is moved to the beginning

• All elements are sorted

During the bubble sort process, what is the significance of the index positions?

• They determine the order of elements in the final sorted array

• They are used to divide the array into subarrays

• They are irrelevant to the sorting process

• They are used to identify which elements to compare and swap

How many iteration cycles were completed in the example provided in the lecture?

• 12

• 13

• 15

• 10

Why is the algorithm called 'bubble sort'?

• Because the smallest element bubbles to the top

• Because the largest element bubbles to the end

• Because it uses bubbles to sort elements

• Because it sorts elements in a circular motion
