Shell Sort Algorithm - Theory, Working, and Pseudocode with Example - Part 1

Dive into a comprehensive 44-minute tutorial on the Shell Sort algorithm, exploring its theory, working principles, and pseudocode with practical examples. Learn how this in-place comparison sort improves upon bubble and insertion sorts by allowing exchanges of far items. Understand the concept of gap or interval and how it affects efficiency, especially for large arrays or when smaller values are towards the end. Examine the algorithm's time and space complexity, including best, worst, and average cases. Follow along with step-by-step explanations, diagrams, and a dry run of the pseudocode to grasp how Shell Sort progresses at each stage. Gain insights into when Shell Sort outperforms other sorting algorithms and how to implement it effectively in your programming projects.
