Description

Create a new file named 'linked_list.c' to implement a basic Singly Linked List.

The implementation should define a struct Node and include at least two functions:

  1. insert_at_beginning(int data): Inserts a new node at the head of the list.
  2. display_list(): Prints all elements in the linked list.

The main function should demonstrate inserting 3 or more elements and then displaying the final list.

Contributor guide

Research direction
Create a struct Node with int data and Node* next. Write insert at beginning to allocate a new node and update head. Write display list to traverse and print. In main, call insert at beginning multiple times and then display.
