Data Structures and Algorithms The Complete Masterclass - Insertion Sort

The video tutorial explains the insertion sort algorithm, starting with an introduction and a basic example. It describes how the list is divided into sorted and unsorted parts, and elements from the unsorted part are inserted into the correct position in the sorted part. The tutorial provides a detailed step-by-step explanation with examples, highlighting the comparison and insertion process. A second example is given to reinforce understanding, and the video concludes with a promise to write code in the next lecture.

What is the initial step in the insertion sort algorithm?

• Divide the list into two parts: sorted and unsorted

• Sort the entire list at once

• Divide the list into three parts

• Pick the largest element and place it at the end

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

• It is inserted at the correct position in the sorted list

• It is ignored and left in the unsorted list

• It is removed from the list

• It is placed at the end of the sorted list

During the insertion sort process, how do you determine where to insert the current element?

• By checking if it is an even or odd number

• By comparing it with each element in the unsorted list

• By finding the largest element in the list

• By comparing it with each element in the sorted list

In the second example, what is the first element considered as part of the sorted list?

• The largest element

• The smallest element

• The first element of the list

• The last element of the list

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

• Move the element to the end of the list

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

• Remove the element from the list

• Swap the element with the first element
