Algorithms · Question 5 · Easy
Merge sort is an example of which algorithm design technique?
- Divide and conquer
- Greedy
- Dynamic programming
- Backtracking
Answer and explanation
Answer: A. Divide and conquer
Explanation: Merge sort divides the array into halves, sorts each half recursively, and combines them by merging, which is divide and conquer.
