From 0 to 1 Data Structures & Algorithms in Java - Merge Sort

The video tutorial explains merge sort, a divide and conquer algorithm that breaks a list into smaller sublists, sorts them, and merges them back together. It highlights the use of recursion in merge sort, visualizes the sorting process, and provides a detailed explanation of the code, including helper methods. The tutorial also discusses the time and space complexity of merge sort, noting its efficiency compared to other sorting algorithms.

Why is it important to understand recursion before learning merge sort?

How does merge sort compare to other sorting algorithms in terms of time complexity?

What are the helper methods used in the implementation of merge sort?

Describe the process of visualizing how merge sort works on a list of elements.
