Selection Sort Visualization

The video tutorial explains the concept of selection sort, a sorting algorithm that selects the minimum element from an unsorted list and swaps it with the first element. The process is repeated for the remaining unsorted elements. The tutorial compares selection sort with bubble sort, highlighting that selection sort is more efficient as it requires fewer swaps. The video also provides a step-by-step demonstration of the selection sort process, emphasizing the importance of minimizing swaps to improve efficiency. The tutorial concludes with a brief mention of implementing selection sort in code.

What is the first step in the selection sort algorithm?

• Swap the first and last elements

• Set the first element as the minimum

• Sort the entire list

• Set the last element as the minimum

How does selection sort improve efficiency compared to bubble sort?

• By sorting elements in reverse order

• By swapping elements multiple times in each iteration

• By swapping only once per iteration

• By using a different sorting algorithm

What happens when a smaller element is found during the selection sort process?

• It is ignored

• It is swapped immediately

• It becomes the new minimum

• The list is reversed

What is the maximum number of swaps in selection sort?

• Equal to the number of elements

• No swaps are needed

• Twice the number of elements

• Half the number of elements

What tool is recommended for better understanding of selection sort?

• Textbook

• Spreadsheet

• Calculator

• Visual Algo
