A simple and quick optimization strategy that aims to get the best immediate result, even if it's not the most efficient in the long run.

What is the Greedy Approach?

Plus

A problem-solving technique that breaks down complex problems into smaller subproblems, solves them individually, & saves the results to minimize time complexity.

What is Dynamic Programming?

Plus

 - Greedy approach seeks immediate results without ensuring long-term efficiency.   - Dynamic approach guarantees optimal solutions by breaking down complex problems into smaller subproblems.

Plus

 - Greedy approach is memory-efficient since it doesn't require revisiting previous choices.   - Dynamic approach requires a DP table for memoization, which increases memory usage.

Plus

 - Greedy approach is faster as it prioritizes immediate results & avoids solving all subproblems.    - Dynamic approach takes more time to solve problems but can be optimized using memoization.

Comparison based on Time Complexity

Plus

 - The Greedy Methodology makes locally optimal choices at each step.  - Dynamic Programming uses a recurring formula to calculate new states.
