Divide and Conquer is a problem-solving technique where you break a problem into smaller subproblems, solve them independently, and then combine the solutions to solve the original problem.
Key Characteristics:
- Divisibility: The problem can be divided into smaller subproblems, often of the same type. For example, in sorting an array, you can divide the array into two smaller parts.
- Independence: Each subproblem should be independent of the others. This means solving one subproblem does not affect the solution to another.
- Combining the Results: After solving the subproblems, you must have a method to combine their solutions to form the final solution for the original problem.
Example: Think of sorting an array using Merge Sort. You divide the array into smaller arrays, sort them individually, and then merge them back together to get the sorted result.
