In a singly linked list, what is the time complexity to insert an element at the beginning?

Step 1: Understand what a singly linked list is. It is a data structure where each element (node) points to the next one.
Step 2: Know that the first element of the list is called the head.
Step 3: To insert a new element at the beginning, you create a new node.
Step 4: Set the new node's next pointer to the current head of the list.
Step 5: Update the head pointer to point to the new node.
Step 6: Realize that these actions (creating a node and updating pointers) do not depend on the size of the list.
Step 7: Conclude that the time taken to insert at the beginning is constant, which is O(1).
