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.
