You are given a code snippet that represents a class definition. Your task is to complete the class definition by implementing a specific method. The class represents a simple linked list, where each node contains a value and a reference to the next node.

Complete the following method in the given code snippet:

```python
def insert(self, value):
    """
    Inserts a new node with the given value at the end of the linked list.

    Parameters:
    value (int): The value to be inserted.

    Returns:
    None
    """
    # Your implementation here
```

You need to implement the `insert` method in the given code snippet to insert a new node with the given value at the end of the linked list.

For example, if the original linked list is `[1, 2, 3]` and you call the insert method with `4` as the value, the linked list should become `[1, 2, 3, 4]`.

You should not modify or reimplement any other part of the code snippet.

Sure, here's an implementation of the `insert` method using the given class definition in Python:

```python
class Node:
    def __init__(self, value):
        self.value = value
        self.next = None

class LinkedList:
    def __init__(self):
        self.head = None

    def insert(self, value):
        new_node = Node(value)

        # Check if the linked list is empty
        if self.head is None:
            self.head = new_node
            return

        # Traverse until the last node
        current_node = self.head
        while current_node.next:
            current_node = current_node.next

        # Insert the new node at the end
        current_node.next = new_node
```

In this implementation, the `insert` method creates a new node with the given value, checks if the linked list is empty, and then traverses to the last node in the linked list. Then, it inserts the new node at the end by setting the `next` pointer of the last node to the new node.

You can use this method to insert a new node with the given value at the end of the linked list.

Sure, I can help with that. Here's how you can implement the `insert` method in the given code snippet:

```python
class Node:
    def __init__(self, value, next=None):
        self.value = value
        self.next = next

class LinkedList:
    def __init__(self, head=None):
        self.head = head

    def insert(self, value):
        """
        Inserts a new node with the given value at the end of the linked list.

        Parameters:
        value (int): The value to be inserted.

        Returns:
        None
        """
        new_node = Node(value)
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node
```

In this implementation, we first create a new node with the given value. If the linked list is empty (i.e., `self.head` is `None`), we set the new node as the head of the list. If the list is not empty, we traverse to the end of the list and set the new node as the next node of the last node.
