Learn about the insertion sort algorithm in this 24-minute video tutorial. Explore how insertion sort works, including its step-by-step process, time complexity, and efficiency for small data sets. Understand the algorithm's comparison to other quadratic sorting methods like selection sort and bubble sort. Follow along with code examples and theoretical explanations to grasp the concept of building a sorted array one item at a time. Gain insights into when insertion sort is most effective and how it compares to other sorting algorithms in data structures and algorithms.
