Flatten a Multilevel Doubly Linked List leetcode
You are given a doubly linked list which in addition to the next and previous pointers, it could have a child pointer, which may or may not point to a separate doubly linked list. These child lists may have one or more children of their own, and so on, to produce a multilevel data structure, as shown in the e…
Custom LinkedList constructor with array as a parameter
I’ve written this program to implement a LinkedList. There are 2 classes: Node and IntLinkedList and the relationship between them is aggregation. In the IntLinkedList class, the constructor’s parameter is an array and I’ve tried to use a for-each loop to add the data of the array to the lin…
Adding two linked lists in java solution results in time limit exceeded
the problem on leetcode: https://leetcode.com/problems/add-two-numbers/ My solution results in time limit exceeded and I cannot understand what’s wrong with my code: Answer It looks like you are never resetting the carry (c) back to 0. Therefore, once you set it to a non-zero value, the loop will never …

Deleting the rear element of a circular linked list
I am trying various methods in a circular linked list in java and one of them is to delete the rear element. I’m pretty sure that my logic is correct but I think there is something wrong in my code. The logic is to browse the list until cur.next is before the rear element and then delete it. Then I
