Question:
What is the time complexity to insert an element at the beginning of a dynamic array?
What is the time complexity to insert an element at the beginning of a dynamic array?
Show Hint
Inserting an element at the beginning of an array requires shifting all the elements, which results in O(n) time complexity.

- O(1)
- O(n)
- O(nlogn)
- O(logn)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In a dynamic array, when an element is inserted at the beginning, all the existing elements have to be shifted one position to the right. Hence, the time complexity for this operation is O(n).
