### Understanding Big-O Notation in Various Data Structures

#### For the following questions, select the operation that is “faster” based on its Big-O running time.
**Write A, B, or C in your answer sheet in each case.**

i. **Deleting a value:**

- **A.** Deleting a value at the head of a linked-list
- **B.** Deleting a value from a sorted array
- **C.** Both are equally fast

ii. **Searching for an element:**

- **A.** Searching for an element in a balanced BST
- **B.** Searching for an element in a sorted array using binary search
- **C.** Both are equally fast

iii. **Finding the minimum element:**

- **A.** Finding the minimum element in a min Heap
- **B.** Finding the minimum element in a sorted array where elements are stored in ascending order
- **C.** Both are equally fast

iv. **Finding the minimum element:**

- **A.** Finding the minimum element in an unsorted array
- **B.** Finding the minimum element in a balanced BST
- **C.** Both are equally fast

v. **Searching for an element:**

- **A.** Searching for an element in a sorted linked list
- **B.** Searching for an element in a balanced BST
- **C.** Both are equally fast

*Explanations:*

1. **Deleting a value:**
    - **Linked List:** Removing the head of a linked list is an O(1) operation, as it involves reassigning the head pointer.
    - **Sorted Array:** Deleting a value can be O(n) due to the need for shifting elements.
   
2. **Searching for an element:**
    - **Balanced BST (Binary Search Tree):** Searching is O(log n).
    - **Sorted Array with Binary Search:** Also O(log n).
  
3. **Finding the minimum element:**
    - **Min Heap:** The minimum element is always at the root, making it an O(1) operation.
    - **Sorted Array (ascending order):** The minimum element is the first element in the array, so it is O(1).
 
4. **Finding the minimum element:**
    - **Unsorted Array:** Finding the minimum requires scanning all elements, making it an
