What is the average time complexity for inserting an element at the beginning of a linked list?
Steps
Concepts
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.
Step 3: Realize that to insert a new node at the beginning, you only need to change a few pointers.
Step 4: Identify that this operation does not depend on the number of elements in the list.
Step 5: Conclude that since the time taken to insert is constant, the time complexity is O(1).
