Divide and conquer is a problem-solving strategy that involves breaking a large problem into smaller, more manageable parts. By tackling these smaller parts individually, it becomes easier to find solutions. This method is often used in computer science, particularly in algorithms, where complex tasks are simplified into simpler sub-tasks. The approach typically consists of three steps: dividing the problem into smaller sub-problems, conquering each sub-problem by solving it, and then combining the solutions to address the original problem. This technique is effective in various fields, including mathematics, engineering, and project management.
