One Byte Explainer : Divide and Conquer !

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer.

Divide and Conquer

Divide and Conquer break problems into smaller and similar subproblems, solving them recursively. After solving subproblems, solutions are combined to solve the original problem. Used in algorithms like merge sort and quicksort. Efficient, but requires a careful merging strategy.

Additional Context

The key steps involved in the Divide and Conquer:

Divide: Break the problem into smaller chunks of subproblems.

Conquer: Solve the subproblems recursively.

Combine: Merge or combine the solutions of the subproblems in order to obtain the solution to the original problem.

Some Applications of Divide and Conquer Algorithm:

1. Quicksort:

• Efficient sorting by partitioning and recursively sorting subarrays.
• Time Complexity: O(n log n) on average, O(n^2) worst-case.

2. Merge Sort:

• Sorting algorithm dividing the array into halves, recursively sorting, and merging.
• Time Complexity: O(n log n) always.

3. Closest Pair of Points:

• Finds the closest pair of points in 2D space.
• Time Complexity: O(n log n).

4. Cooley–Tukey FFT Algorithm:

• Fast Fourier Transform algorithm.
• Time Complexity: O(N log N).

5. Karatsuba Algorithm:

• Fast multiplication of two binary strings.
• Time Complexity: O(n^1.59).
