Explanation: While traversing Write a function detectAndCountLoop() that checks whether a given Linked List contains loop and if loop is present then returns count of nodes in loop. For example, the loop Time Complexity: O(N), where N is the number of nodes in the linked list. Circular linked lists are especially helpful Write a function detectAndCountLoop() that checks whether a given Linked List contains loop and if loop is present then returns count of nodes in loop. Re. In the inner loop, check if any of the nodes of the 2nd list Each node in a linked list contains the data and a reference (or link) to the next node in the sequence. For example, A circular linked list is a data structure where the last node connects back to the first, forming a loop. Recursive Approach to Find the Length of a Linked List: The Find the length of loop in linked list Corporate & Communications Address: A-143, 7th Floor, Sovereign Corporate Tower, Sector- 136, Noida, Uttar Pradesh (201305) Therefore, no loop is present in the linked list. The list should only be traversed once. For example, the following doubly linked list should be changed to Given two Linked Lists L1 and L2, the task is to generate a new linked list with no common elements from the given two linked lists. For example, if the given linked list is 1->2->1->2->1->3->1 and the given Given the head of a linked list, determine whether the list contains a loop. Input: 20->4->54->6->NULL Output: No loop is detected. Note: 'c' is the position of the Medium Problems on Linked List: Swap Nodes in Pairs; Detect loop in a linked list ; Length of loop in linked list ; Design Browser History; Remove duplicates from a sorted linked Given the head of a linked list, determine whether the list contains a loop. Each node in the linked list contains a positive integer value. Examples: Input : 1->2->3->4->NULL Given the head of a linked list that may contain a loop. For example, the loop is present in below-linked list and length of the Write a function detectAndRemoveLoop() that checks whether a given Linked List contains a loop and if the loop is present then removes the loop and returns true. The task is to find the Starting node of the loop in the linked list if Output: count of nodes is 5. For example, the loop . When one pointer reaches the end of its Given a doubly linked list, The task is to find the number of nodes in the given doubly linked list. Auxiliary Space: O(1), no extra space is required, so it is a constant. A linked list is called circular if it is not NULL-terminated and all nodes are connected in the form of a cycle. Recursive Solution: int Given a Doubly Linked List, the task is to reverse the given Doubly Linked List. If the fast pointer ever catches up Given the head of a linked list. A loop exists in a linked list if the next pointer of the last node points to any other node in Write a function detectAndCountLoop() that checks whether a given Linked List contains loop and if loop is present then returns count of nodes in loop. For example, the loop Given a linked list of size N. Corporate & Communications Address: A-143, 7th Floor, Sovereign Corporate Tower, Sector- 136, Noida, Uttar Pradesh (201305) Registered Address: @GeeksforGeeks, Sanchhaya Time complexity: O(N), Where N is the size of the linked list Auxiliary Space: O(1), As constant extra space is used. Examples: Input: 4 -> 1 Write a function that takes a list sorted in non-decreasing order and deletes any duplicate nodes from the list. This structure allows for continuous traversal without any interruptions. For example, the loop is present in below-linked list and length of the Write a function detectAndCountLoop() that checks whether a given Linked List contains loop and if loop is present then returns count of nodes in loop. This solution works in O(n) but requires additional information with Given the head of a linked list that may contain a loop. Note: 'c' is the position of the A singly linked list is a fundamental data structure, it consists of nodes where each node contains a data field and a reference to the next node in the linked list. Your task is to determine if the linked list contains a loop. The task is to find the length of the linked list, where length is defined as the number of nodes in the linked list. For example, the loop Given the head of a linked list, determine whether the list contains a loop. A loop means that the last node of the linked list is connected back to a node in the same list. Using linear traversal - O(n) time Given a singly linked list. Auxiliary Space: O(1) Traversal of Singly Linked List (Recursive Approach) We can also traverse the singly linked list using recursion.
