Divide and Conquer algorithm is a problem-solving strategy that involves.
- Divide : Break the given problem into smaller non-overlapping problems.
- Conquer : Solve Smaller Problems
- Combine : Use the Solutions of Smaller Problems to find the overall result.
Examples of Divide and Conquer are Merge Sort, Quick Sort, Binary Search and Closest Pair of Points.
