Circular Linked List Complexity Time Complexity Space Complexity Insertion Operation O(1) or O(n) O(1) Deletion Operation O(1) O(1) 1. Complexity of Insertion Operation The insertion operations that do not require traversal have the time complexity of O(1). And, an insertion that requires ...

Insertion at the beginning Insertion in-between nodes Insertion at the End Suppose we have a double-linked list with elements 1, 2, and 3. Original doubly linked list 1. Insertion at the Beginning Let's add a node with value 6 at the beginning of the doubly linked list we made above...
This article will explain insertion sort for a doubly-linked list; moving on, we will see its algorithm in detail with itsC++code, and at last, we will see its space and time complexity. First, we need to know what a doubly-linked list is? Adoubly linked listis a linked data structur...
Explanation: In the figure above, there is a sorted circular list of three elements. You are given a reference to the node with value 3, and we need to insert 2 into the list. The new node should be inserted between node 1 and node 3. After the insertion, the list should look like...
Familiarize yourself with common operations such as insertion, deletion, and traversal.熟悉插入、删除、遍历等常用操作。 Practice reversing a linked list, finding the middle element, and detecting cycles.练习反转链表、查找中间元素以及检测循环。 3. Use Multiple Pointers 3. 使用多个指针 Many linked list...
Linked List Cycle Given a linked list, determine if it has a cycle in it. 知道概念之后就很简单。两个pointer,一个每次走两步,一个每次走一步。如果有环,两个pointer必然相遇。 1 2 3 4 5 6 7 8 9 10 11 12 13 public class Solution { public boolean hasCycle(ListNode head) { ListNode ...

Insertion: O(1) (insertion only concerns the inserted node and does not move the others) Deletion: O(1) (deletion only concerns the deleted node and does not move the others) Space complexity: O(n) Double linked list Each node contains the data itself and two pointers. The first one is...
