What is lazy propagation in segment tree?

With Lazy propagation, we update only node with value 27 and postpone updates to its children by storing this update information in separate nodes called lazy nodes or values. ... A non-zero value of lazy[i] means that this amount needs to be added to node i in segment tree before making any query to the node.

What is the total size of the array representing segment tree if'n No of nodes is not a power of 2?

What is the total size of the array representing segment tree? If n is a power of 2, then there are no dummy nodes. So the size of the segment tree is 2n-1 (n leaf nodes and n-1) internal nodes. If n is not a power of 2, then the size of the tree will be 2*x – 1 where x is the smallest power of 2 greater than n.

What is a segment?

(Entry 1 of 2) 1 : a portion cut off from a geometric figure by one or more points, lines, or planes: such as. a : the area of a circle bounded by a chord and an arc of that circle. b : the part of a sphere cut off by a plane or included between two parallel planes.

What is merge sort tree?

The key idea is to build a Segment Tree with a vector at every node and the vector contains all the elements of the sub-range in a sorted order. And if we observe this segment tree structure this is somewhat similar to the tree formed during the merge sort algorithm(that is why it is called merge sort tree)

Which of the following structure can handle updates and query in log n time on an array?

Which of the following data structures can handle updates and queries in log(n) time on an array? Explanation: Correct answer is Segment Tree.

Which among the following is a LIFO data structure?

The data structure that implements LIFO is Stack.

Which of the following is false about binary search tree?

Which of the following is false about a binary search tree? ... Explanation: As a binary search tree consists of elements lesser than the node to the left and the ones greater than the node to the right, an inorder traversal will give the elements in an increasing order.

What is the complexity of searching for a particular element in a singly linked list?

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).

Can we use linked list in binary search?

Yes, Binary search is possible on the linked list if the list is ordered and you know the count of elements in list. But While sorting the list, you can access a single element at a time through a pointer to that node i.e. either a previous node or next node.

Can you do binary search on linked list?

In Linked List we can do binary search but it has time complexity O(n) that is same as what we have for linear search which makes Binary Search inefficient to use in Linked List.

What is the time complexity of linked list insertion?

The task is to insert the given elements at the middle position in the linked list one after another. Each insert operation should take O(1) time complexity.

What is the item at position N?

In the linked list, we need to traverse through each element until we reach the nth position. Time taken to access an element represented in arrays is less than the singly, doubly and circular linked lists. Thus, array implementation is used to access the item at the position n.

Why is array insertion o n?

According to academic literature for arrays it is constant O(1) and for Linked Lists it is linear O(n). ... Insert and delete are O(1) because the array is an unsorted data structure.

Why is linked list insertion o1?

That's why insertion is O(n) . A LinkedList consists of a chain of nodes; each node is separated allocated. And so while inserting, it's not necessary to traverse all the nodes. And that's why it has the complexity O(1) .

How do we use insertion and deletion in linked list?

Insert Elements to a Linked List

Insert at the beginning. Allocate memory for new node. Store data. Change next of new node to point to head. ...
Insert at the End. Allocate memory for new node. Store data. Traverse to last node. ...
Insert at the Middle.

Which operations are dependent on the length of the linked list?

7. You are given pointers to first and last nodes of a singly linked list, which of the following operations are dependent on the length of the linked list? Explanation: Deletion of the first element of the list is done in O (1) time by deleting memory and changing the first pointer.

Which of the following is not good for linked list?

Explanation: Linked lists are not suitable to for the implementation of Binary search. Explanation: In the worst case, the element to be searched has to be compared with all elements of linked list.

Which of the following is application of linked list?

Applications of Circular Linked List are as following: It can also be used to implement queues by maintaining a pointer to the last inserted node and the front can always be obtained as next of last. Circular Doubly Linked Lists are used for the implementation of advanced data structures like Fibonacci Heap.

Which linked list has no beginning and no end?

Thus, a circular linked list has no beginning and no ending. It is just a singly linked list in which the link field of the last node contains the address of the first node of the list. That is, the link field of the last node does not point to NULL rather it points back to the beginning of the linked list.

What are different types of linked list?

There are three common types of Linked List.

Singly Linked List.
Doubly Linked List.
Circular Linked List.

What is link list and its types?

Following are the various types of linked list. Simple Linked List − Item navigation is forward only. Doubly Linked List − Items can be navigated forward and backward. Circular Linked List − Last item contains link of the first element as next and the first element has a link to the last element as previous.

What is the difference between circular linked list and linear linked list?

Linear linked list is a data structure where the last element is linked to a null object, while in circular linked list, the last element is linked to the first element.

How will you explain circular linked list?

Circular Linked List is a variation of Linked list in which the first element points to the last element and the last element points to the first element. Both Singly Linked List and Doubly Linked List can be made into a circular linked list.

Why do we use circular linked list?

A circular linked list can be a singly circular linked list or doubly circular linked list. Advantages of Circular Linked Lists: 1) Any node can be a starting point. ... It is convenient for the operating system to use a circular list so that when it reaches the end of the list it can cycle around to the front of the list.

What is difference between list and array?

Array: An array is a vector containing homogeneous elements i.e. belonging to the same data type....Output :
List Array
Can consist of elements belonging to different data types Only consists of elements belonging to the same data type
