Welcome to my dynamic programming repository where I explore and explain solutions to classic problems using both recursion and dynamic programming techniques. This repository serves as a practical reference for coding enthusiasts interested in understanding and applying dynamic programming strategies to solve problems efficiently.

This repository includes Python scripts that demonstrate dynamic programming and recursion solutions to well-known problems, currently featuring:
- Fibonacci Sequence (Leetcode 509)
- Climbing Stairs (Leetcode 70)
Each solution is discussed with respect to both its recursive and dynamic programming implementations, including analysis of time and space complexities.
To clone and run these scripts locally, use the following commands:
git clone https://github.com/yourusername/dynamic-programming-problems.git
cd dynamic-programming-problemsDescription: The Fibonacci sequence is a series of numbers where a number is the sum of the two preceding ones, usually starting with 0 and 1.
Example Usage:
python fibonacci.py 10Detailed Analysis: Includes performance comparison of recursive vs dynamic programming approaches with visual aids.
Description: Determine the number of ways to climb n steps when you can climb either one or two steps at a time.
Example Usage:
python climbing_stairs.py 5Detailed Analysis: Focuses on optimizing the recursive solution using dynamic programming techniques to reduce time complexity from exponential to polynomial.
To run any script, navigate to the specific problem directory and run the Python script with an appropriate argument. For example:
python fibonacci.py 10Replace 10 with any number to compute its Fibonacci value using dynamic programming.
