Data Structures and Algorithms The Complete Masterclass - Selection Sort Visualization

The video tutorial explains the selection sort algorithm, starting with an introduction to its basic concept. It details the process of selecting the minimum element and swapping it with the base value, comparing it to bubble sort in terms of efficiency. The tutorial emphasizes the iterative nature of selection sort and concludes with a brief mention of implementing the algorithm in code.

What is the first step in the selection sort algorithm?

• Sort the list in descending order

• Set the first element as the minimum

• Set the last element as the minimum

• Swap the first and last elements

How does selection sort improve efficiency compared to bubble sort?

• By sorting elements in reverse order

• By using more memory

• By reducing the number of swaps per iteration

• By increasing the number of comparisons

In selection sort, what happens after finding the new minimum in an iteration?

• The new minimum is added to the end of the list

• The new minimum is ignored

• The new minimum is swapped with the last element of the sorted list

• The new minimum is swapped with the first element of the unsorted list

What is the maximum number of swaps in selection sort?

• Equal to the number of comparisons

• Twice the number of elements

• Equal to the number of elements

• Half the number of elements

What is recommended for better understanding of selection sort?

• Reading more books

• Using visual tools

• Practicing with bubble sort

• Ignoring the algorithm
