Data Structures and Algorithms The Complete Masterclass - Merge Sort

The video tutorial covers the merge sort algorithm, emphasizing its importance in interviews and exams due to its efficient N log N complexity. It explains the divide and conquer approach, highlighting the use of recursion. The tutorial details the process of splitting arrays into subarrays and then merging them while sorting. A visualization of the merge sort process is provided to aid understanding.

In what scenarios might merge sort be preferred over other sorting algorithms?

What role does recursion play in the implementation of merge sort?

Can you explain how merge sort achieves a sorted array from unsorted input?

What are the advantages and disadvantages of using merge sort?
