Python 3: Project-based Python, Algorithms, Data Structures - Project phase 2: Get input from user for size and range

The video tutorial introduces the insertion sort algorithm, explaining its complexity as O(n^2) and comparing it to bubble and selection sorts. The instructor walks through the insertion sort process using a list of numbers, detailing how the key index is used to compare and swap elements to achieve a sorted list. Implementation notes emphasize the importance of tracking the key index and using nested loops. An assignment is given to implement the algorithm in Python, with tips for testing and debugging provided.

What is the primary objective of the insertion sort algorithm as described in the text?

Explain the role of the 'key' in the insertion sort algorithm.

Describe the process of comparing elements in the insertion sort algorithm.

What happens when the condition for a swap is met during the sorting process?

How does the algorithm ensure that the key index remains stable during the sorting process?

What is the time complexity of the insertion sort algorithm and why?

What debugging technique is suggested for tracking the state of the list during the algorithm's execution?
