Question
![## Solving the Recurrence Relation
### Problem Statement:
Solve the recurrence:
\[ T(n) = 2T\left(\frac{2}{3}n\right) + n^2 \]
First, solve by directly adding up the work done in each iteration, and then use the Master Theorem.
### Instructions:
Note that this question has two parts:
(a) Solving the problem by adding up all the work done (step by step).
(b) Using the Master Theorem.
### Detailed Explanation:
1. **Direct Addition**:
- Break down the problem into progressively smaller sub-problems by iteratively substituting the recurrence relation.
- Evaluate the total work done at each level of recursion and sum it up.
2. **Using Master Theorem**:
- Apply the Master Theorem to determine the asymptotic behavior of the recurrence relation.
- Identify values for \(a\) (the number of subproblems), \(b\) (the factor by which the subproblem size is divided), and \(f(n)\) (the cost outside the recursive calls).
- Determine which case of the Master Theorem applies to your recurrence relation.
### Example Solution (Not Given Here):
- Demonstrate a step-by-step breakdown of the recurrence relation.
- Show how the Master Theorem is applied to derive the asymptotic complexity.
For a complete walkthrough and detailed solutions, please see the respective sections on direct addition and the Master Theorem application.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F206fff43-6971-4e97-bcab-c7e54aed7743%2F3aefac09-dcb5-4fb8-88f9-01b5eec5587b%2Fnrp7vy_processed.png&w=3840&q=75)
