What is the base case in a Divide and Conquer algorithm?
Updated Apr 28, 2026
Short answer
The simplest instance of the problem that can be solved directly without further division.
Deep explanation
Divide and Conquer is essential for efficient algorithms. The simplest instance of the problem that can be solved directly without further division. 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?
