Study Notes
Dynamic Programming
- Recursive solutions have a time complexity of O(n) explicitly, but may have slower runtime due to the overhead of recursive calls.
Types of Dynamic Programming
- Bottom-up iterative DP is considered a solution.
- Top-down recursive DP with memoization is another solution.
Complexity
- The bottom-up solution has a time complexity of O(n).
Advantages
- The main advantage of using top-down recursive DP with memoization is to avoid redundant computations.
Dynamic Programming Technique
- Dynamic programming falls under the category of Divide and Conquer algorithmic techniques.
Memoization
- The purpose of memoization in dynamic programming is to store the results of expensive function calls and reuse them when the same inputs occur again.
Suitable Problems
- Dynamic programming is suitable for problems that have overlapping subproblems and optimal substructure.
Iterative Counterpart
- The iterative counterpart of the top-down approach in dynamic programming is the bottom-up approach.
Fibonacci Number Sequence
- Both recursive and iterative solutions reuse intermediate results in the Fibonacci number sequence.
