Motivation
Lesson 2 of 9 in Coddy's Merge Sort - DSA Series course.
Merge Sort splits the problem into smaller subproblems, solves each one, and combines the results. That combine step, merging two already sorted lists, is the heart of the algorithm.
Why learn Merge Sort?
- Fast and predictable: it runs in O(n log n) time in the best, average, and worst case.
- Stable: equal elements keep their original relative order.
- Great for large data: it works well when data does not fit in memory (external sorting) and for linked lists.
- Divide and conquer: it teaches a pattern used across many advanced algorithms.
