### Tree Traversal Exercises

Given the tree rooted at **A**, answer the following questions regarding different tree traversal methods.

#### Tree Structure:
The tree is structured as follows:

- Root: A
  - Children of A: B, C, D
    - Children of B: E, F
      - Children of E: K, L
      - Child of F: M
    - Child of C: G
    - Children of D: H, I, J
      - Children of I: N, O
        - Child of N: P
        - Children of O: Q, R

#### Exercises:

(a) **Breadth-First Search (BFS):**  
List the order of the vertices produced.  
Order: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R

(b) **Pre-Order Depth First Search (DFS):**  
List the order of the vertices produced.  
Order: A, B, E, K, L, F, M, C, G, D, H, I, N, P, O, Q, R, J

(c) **Post-Order Depth First Search (DFS):**  
List the order of the vertices produced.  
Order: K, L, E, M, F, B, G, C, H, P, N, Q, R, O, I, J, D, A
