What do you mean by linked list?

Linked lists are linear data structures that hold data in individual objects called nodes. Linked lists are often used because of their efficient insertion and deletion. They can be used to implement stacks, queues, and other abstract data types.

Why linked list is needed?

What is the time complexity to count the elements in the linked list?

In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes which together represent a sequence.

How do you clear a linked list in C++?

3. What is the time complexity to count the number of elements in the linked list? Explanation: To count the number of elements, you have to traverse through the entire list, hence complexity is O(n).

How do you make a linked list empty?

The process of deletion includes:

How do I check if a list is empty C++?

list::empty() is an inbuilt function in C++ STL which is declared in header file. list::empty() checks whether the given list container is empty(size is 0) or not, and returns true value if the list is empty and false if the list is not empty….

What is ArrayList in Java with example?

Java ArrayList class uses a dynamic array for storing the elements. It is like an array, but there is no size limit. The ArrayList in Java can have the duplicate elements also. It implements the List interface so we can use all the methods of List interface here. The ArrayList maintains the insertion order internally.

Is an ArrayList an ADT?

Again, one can describe that as an abstract data structure. ArrayList is one of possible implementations of the List interface. As such it also implements the Collection interface. So it is a concrete data structure (and a collection itself) implementing more than one abstract data structures.
