In merge two sorted linked lists we have given head pointer of two linked lists, merge them such that a single linked list is obtained which has nodes with values in sorted order. return the head pointer of the merged linked list. Note: merge the linked list in-place without using …
Problem Given a linked list. The elements of the linked list are in increasing order. Convert the given linked list into a highly balanced binary search tree. A highly balanced binary search tree is a binary search tree in which the difference between the depth of two subtrees of any …
What is merge two sorted lists problem on leetcode? This is so interesting question asked so many times in compnies like Amazon, Oracle, Microsoft, etc. In this problem(Merge Two Sorted Lists Leetcode), we have given two linked lists. Both linked lists are in increasing order. Merge both linked list in …
Problem In Reverse Nodes in K-Group problem we have given a linked list, Reverse the linked list in a group of k and return the modified list. If the nodes are not multiple of k then reverse the remaining nodes. The value of k is always smaller or equal to …
Add two numbers is a problem in which we have given two non-empty linked list representing a non-negative integer. The digit are store in reverse order and every node must contain only a single digit. Add the two numbers and print the result by using a linked list. Input Format …
Problem Statement The problem “reverse a linked list” states that we are given the head of the linked list. We have to reverse the linked list by changing the links between them and return the head of the reversed linked list. Example 10->20->30->40->NULL NULL<-10<-20<-30<-40 Explanation We have reversed the linked …
Problem Statement In the “Insert Node in the Sorted Linked List” problem we have given a linked list. Insert a new node in the sorted linked list in a sorted way. After inserting a node in the sorted linked list the final linked list should be the sorted linked list. …
Problem Statement In the “Detect a loop in the Linked List” problem we have given a linked list. Find whether there is loop or not. If there is a loop in the linked list then some node in the linked list will be pointing to one of the previous nodes …
Problem Statement In the “Find Nth Node” problem we have given a linked list to find the nth node. The program should print the data value in the nth node. N is the input integer index. Example 3 1 2 3 4 5 6 3 Approach Given a linked list …
Problem Statement In the “Swap Kth Node from beginning with Kth Node from End” problem, we have given a linked list. Swap kth node from beginning_with kth node from the end. We should not swap the values, we should swap pointers. Example 2 1 2 3 4 5 6 1 …
