What is the time complexity of inserting an element at the beginning of a linked list?

Step 1: Understand what a linked list is. A linked list is a data structure where each element (node) points to the next one.
Step 2: Know that inserting an element at the beginning means adding a new node before the first node of the linked list.
Step 3: Realize that to insert a new node at the beginning, you only need to change a few pointers.
Step 4: The new node will point to the current first node, and then you update the head of the list to point to the new node.
Step 5: Since this operation does not depend on the number of elements in the list, it takes the same amount of time regardless of the list size.
Step 6: Therefore, the time complexity for this operation is constant time, which is denoted as O(1).
