Evaluate two sorting or two search algorithms : Selection sort implementation

This video tutorial explains the implementation of the selection sort algorithm. It begins with an overview and setup, followed by creating a spot marker index. The tutorial then covers building comparison logic and performing swaps within the algorithm. Finally, it demonstrates iterating through the list using loops to complete the sorting process. The video provides a step-by-step guide to understanding and coding the selection sort algorithm.

What is the primary focus of the video tutorial?

• Learning about data structures

• Understanding the selection sort algorithm

• Reviewing the bubble sort algorithm

• Implementing a new sorting algorithm

What is the initial task in setting up the selection sort function?

• Writing a complex algorithm

• Designing a user interface

• Creating a new programming language

• Creating a file and defining a basic function

What is the purpose of the spot marker in the selection sort algorithm?

• To mark the end of the list

• To sort the list in descending order

• To identify the largest element

• To reference the current position for potential swaps

How is the initial comparison made in the selection sort algorithm?

• By comparing each element to the first element

• By comparing each element to the spot marker

• By comparing each element to the last element

• By comparing each element to the middle element

What is the role of the inner loop in the selection sort algorithm?

• To iterate through the list and perform swaps

• To reverse the list order

• To find the largest element

• To print the sorted list

What happens when a swap candidate is found in the selection sort algorithm?

• The candidate is moved to the end of the list

• The candidate is swapped with the spot marker

• The candidate is ignored

• The list is reversed

What is the purpose of the outer loop in the selection sort algorithm?

• To print the sorted list

• To reverse the list order

• To find the largest element

• To iterate through all elements and ensure sorting

Why is it important to adjust the starting point of the inner loop?

• To ensure the list is sorted in descending order

• To prevent unnecessary comparisons with already sorted elements

• To increase the complexity of the algorithm

• To make the algorithm run indefinitely

What issue arises if the inner loop starts from the beginning of the list each time?

• The list will be printed multiple times

• The list will be sorted in descending order

• The algorithm will run faster

• The algorithm will not sort the list correctly

What is the final outcome of the selection sort algorithm as implemented in the video?

• A list sorted in descending order

• A list sorted in ascending order

• A list with duplicate elements

• A list with missing elements
