## What is the time complexity of removing a value from a sorted linked list of size n?

If you want to delete a specific element, the time complexity is O(n) (where n is the number of elements) because you have to find the element first.

If you want to delete an element at a specific index i , the time complexity is O(i) because you have to follow the links from the beginning..

## What is the time complexity of adding element to linked list?

If you have the reference of the node to insert after the operation is O(1) for a linked list. For an array it is still O(n) since you have to move all consequtive nodes. The most common cases are probably inserting at the begining or at the end of the list (and the ends of the list might take no time to find).

## Is linked list sorted?

If the head points to NULL which means that the linked list is empty, then we return true meaning that the linked list is sorted. We loop through the entire linked list and for each node we check if the value in current node is greater than the value in next node.

## How do I remove duplicate nodes from a linked list?

Input the elements of the linked list in sorted order. Traverse from the head of the sorted linked list. While traversing, compare the current node with the next node. If data of the next node is the same as the current node then delete the next node.

## What is the time complexity of array?

Arrays. Because it takes a single step to access an item of an array via its index, or add/remove an item at the end of an array, the complexity for accessing, pushing or popping a value in an array is O(1). Whereas, linearly searching through an array via its index, as seen before, has a complexity of O(n).

## What is the time complexity of circular linked list?

Explanation: Time complexity of inserting a new node at the head of the list is O(n) because you have to traverse through the list to find the tail node. 10. Consider a small circular linked list.

## What is the time complexity of deleting from the rear end of the linked implementation as a singly linked list?

What is the time complexity of deleting from the rear end of the dequeue implemented with a singly linked list? Explanation: Since a singly linked list is used, first you have to traverse till the end, so the complexity is O(n). 8.

## What is an ordered linked list?

(data structure) Definition: A linked list whose items are kept in some order.

## What are the uses of linked list?

These nodes hold both the data and a reference to the next node in the list. 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.

## What is the best case space complexity for deletion in a linked list?

The time complexity in this case is O(n). In cases where the node to be deleted is known only by value, the list has to be searched and the time complexity becomes O(n) in both singly- and doubly-linked lists. Actually deletion in singly linked lists can also be implemented in O(1).

## What is a memory efficient doubly linked list?

Explanation: Memory efficient doubly linked list has only one pointer to traverse the list back and forth. … It uses bitwise XOR operator to store the front and rear pointer addresses. Instead of storing actual memory address, every node store the XOR address of previous and next nodes.

## Can linked list have duplicates?

If you don’t want duplicates, you should be using a Set ; if you only want a list so that you can keep the elements in the same order they were inserted, you can use a LinkedHashSet to get the best of both worlds: a Set that iterates predictably like a LinkedList .

## What is the advantage of doubly linked list?

Following are advantages/disadvantages of doubly linked list over singly linked list. 1) A DLL can be traversed in both forward and backward direction. 2) The delete operation in DLL is more efficient if pointer to the node to be deleted is given. 3) We can quickly insert a new node before a given node.

## How can you tell if a linked list is circular?

To check whether the linked list is circular or not, we will store the header node into some other variable, then traverse the list, if we get null at the next part of any node, then that is not circular, otherwise we will check the next node is same as the stored node or not, if so then that is circular.

## What type of linked list is best answer?

## What is the memory efficient linked list?

This memory efficient Doubly Linked List is called XOR Linked List or Memory Efficient as the list uses bitwise XOR operation to save space for one address. In the XOR linked list, instead of storing actual memory addresses, every node stores the XOR of addresses of previous and next nodes.

## Why do we use circular linked list?

Circular linked lists (singly or doubly) are useful for applications that need to visit each node equally and the lists could grow. If the size of the list if fixed, it is much more efficient (speed and memory) to use circular queue.
