Question 1

What are the three steps of the divide and conquer approach?

Accepted Answer

The three steps of the divide and conquer approach are: 1. Divide: Break the problem into smaller, independent subproblems. 2. Conquer: Solve the subproblems recursively. If the subproblems are small enough, solve them directly. 3. Combine: Combine the solutions of the subproblems to solve the original problem.

Question 2

What is the time complexity of Merge Sort?

Accepted Answer

The time complexity of Merge Sort is O(n log n) in all cases (worst, average, and best). This is because the array is always divided into two halves, and the merge operation takes linear time.
