Explain the Merge Sort process briefly.
Updated Apr 28, 2026
Short answer
Split the array into two halves, sort them recursively, and merge the sorted halves.
Deep explanation
Divide and Conquer is essential for efficient algorithms. Split the array into two halves, sort them recursively, and merge the sorted halves. It transforms a large, complex problem into manageable chunks, reducing the overall computational effort compared to brute-force approaches.
Real-world example
Searching for a word in a physical dictionary.
Common mistakes
- Forgetting the base case, leading to infinite recursion/StackOverflow.
Follow-up questions
- Is Binary Search better than Linear Search?
