Arrays Linked Lists Questions Long
The time complexity of deleting an element from the beginning of a linked list using iteration is O(1), also known as constant time complexity.
In a linked list, each element (node) contains a reference to the next element in the list. To delete an element from the beginning of the linked list, we simply need to update the reference of the head node to point to the next node, effectively removing the first element.
Since the operation only involves updating a single reference, regardless of the size of the linked list, the time complexity remains constant. It does not depend on the number of elements present in the linked list.
Therefore, the time complexity of deleting an element from the beginning of a linked list using iteration is O(1).
