Describe the process of inserting an element at the beginning of a linked list.

To insert an element at the beginning of a linked list, the following steps need to be followed:

1. Create a new node: First, create a new node with the given element that needs to be inserted at the beginning of the linked list.

2. Set the new node's next pointer: Set the next pointer of the new node to point to the current head of the linked list. This ensures that the new node is now connected to the rest of the linked list.

3. Update the head pointer: Update the head pointer of the linked list to point to the new node. This makes the new node the new head of the linked list.

The process can be summarized in the following steps:

1. Create a new node with the given element.
2. Set the new node's next pointer to point to the current head of the linked list.
3. Update the head pointer to point to the new node.

By following these steps, the element is successfully inserted at the beginning of the linked list. The time complexity of this operation is O(1) since it does not depend on the size of the linked list.
