Insertion Sort Algorithm Concepts

The video tutorial demonstrates the implementation of the insertion sort algorithm in Python. It begins with setting up a function that takes a list as a parameter. The instructor explains how to iterate through the list, starting from the second element, and compares each element to those on its left. The process involves shifting elements to the right and inserting the current element in its correct position. The tutorial concludes with testing the algorithm to ensure it sorts the list correctly.

What is the expected outcome after running the insertion sort function on a list?

• The list is sorted in ascending order

• The list is reversed

• The list is sorted in descending order

• The list remains unchanged

What does the function return after sorting the list?

• The sorted list

• A boolean indicating success

• The original list

• Nothing, it sorts in place

What was the result of testing the insertion sort function with a sample list?

• The function returned an error

• The list was partially sorted

• The list was sorted correctly

• The list was not sorted

What is the primary task described in the video?

• Implementing a bubble sort algorithm

• Implementing an insertion sort algorithm

• Implementing a quicksort algorithm

• Implementing a merge sort algorithm

In the insertion sort function, what is the parameter taken by the function?

• A set

• A list

• A tuple

• A dictionary

Why does the iteration start from the second element in the list?

• Because the first element is already sorted

• Because there is nothing to compare the first element with

• Because the first element is always the largest

• Because the first element is always the smallest

What is the purpose of the variable 'i' in the comparison process?

• To store the current value being compared

• To track the index of the current element

• To track the index of elements to the left

• To store the length of the list

What condition is used to continue the while loop during the comparison?

• While i is not equal to the index

• While i is less than the length of the list

• While i is greater than or equal to 0

• While i is equal to the index

What happens when the current value is less than the item at index 'i'?

• The item at index 'i' is shifted to the left

• The item at index 'i' is shifted to the right

• The current value is shifted to the right

• The current value is shifted to the left

What does the function do when the current value is not less than the item being compared?

• It continues to shift the current value

• It stops the shifting process

• It shifts the current value to the left

• It shifts the current value to the right
