Insertion Sort

The video tutorial introduces the concept of insertion sort, a sorting algorithm that involves dividing a list into sorted and unsorted parts. The instructor provides two examples to demonstrate the process of inserting elements from the unsorted list into the sorted list by comparing and positioning them correctly. The tutorial concludes with a brief mention of the next lecture, which will cover coding the insertion sort algorithm.

What is the initial step in the insertion sort process?

• Pick the largest element first

• Reverse the list

• Sort the entire list at once

• Divide the list into two parts: sorted and unsorted

In the insertion sort example, what happens if the element from the unsorted list is smaller than the current element in the sorted list?

• It is discarded

• It is inserted after the current element

• It is inserted before the current element

• It is compared with the next element in the unsorted list

During the insertion sort process, what is done after comparing an element from the unsorted list with all elements in the sorted list?

• The element is swapped with the first element of the sorted list

• The element is inserted at the correct position in the sorted list

• The element is added to the end of the unsorted list

• The element is removed from the list

In the new example, what is the first element considered as in the sorted list?

• The middle element of the list

• The first element of the list

• The largest element of the list

• The last element of the list

What is the final step in the insertion sort process for each element from the unsorted list?

• Swap the element with the first element of the sorted list

• Move the element to the end of the list

• Remove the element from the unsorted list

• Insert the element at its correct position in the sorted list
