What is the time complexity of inserting a new node at the beginning of a singly linked list?Group of answer choicesO(n)O(1)O(log n)O(n^2)
Question
Solution 1
The time complexity of inserting a new node at the beginning of a singly linked list is O(1).
Here's why:
Step 1: Create a new node. This operation takes constant time, O(1).
Step 2: Point the new node to the current head of the linked list. This operation also takes constant time, O(1).
