Data Structures and Algorithms The Complete Masterclass - Implementing Insertion Sort

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