Implementing Insertion Sort

The video tutorial explains the insertion sort algorithm, starting with an unsorted list and treating the first element as sorted. It details the process of selecting a key, comparing it with elements in the sorted list, and inserting it in the correct position. The tutorial uses loops to iterate through the list, comparing and shifting elements as needed. The video concludes with a demonstration of the algorithm's functionality and a brief mention of its complexity, preparing viewers for the next lecture.
