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.

Describe how the key is inserted into the sorted list.

What happens when the last element is less than the key during the comparison?

Summarize the overall process of the insertion sort algorithm.
