Insert node not values in end of linked lists

时光毁灭记忆、已成空白 提交于 2019-12-08 09:41:47
问题 Lets say I have some linked lists already available and I want to store first node of each individual list into another list so that I can recall this list to display the original lists. I think we have to use two different structures. I am already successful in retaining original lists and displaying them using Array of first nodes of individual lists but I want to create a linked list of individual list to implement same. It has the expected output but as I said I want to use linked list

linked list : how to delete last node, where we have pointer to last node in a single linked list

问题 In a single linked list, we can delete a node with holding pointer to it. This can be achieved by copying next node data into current node until we reach end. But, How can we delete last node by holding and knowing pointer to self ? -Thanks 回答1: This is generally not possible. You need the address of the node before the last node. This node should have it's next pointer set to NULL . The node before last cannot be directly accessed from the last node in a singly linked list. However, if you

LinkedList Memory Leak

喜夏-厌秋 提交于 2019-12-08 09:18:09
问题 I am attempting to debug an application that is hanging. The program uses a queue implemented with a LinkedList , and during stress testing I've discovered that the program stops responding due to running out of heap memory. I analyzed the heap dump and found that memory seems to be leaking from the LinkedList . The relevant part of the heap dump: ▶java.net.Vectior @ 0xff5eacd0 ▶▶java.util.Vector @ 0xff629f30 ▶▶▶java.lang.Object[1280] @ 0xff629f50 ▶▶▶▶class com.itnade.vsm.staticobject

Arrays or linked-list for frequently random access?

问题 I'm using lists and arrays very often, I am wondering what is faster, array or list? Let's say we have array of integers and linked-list, both hold same values. int array_data[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; typedef struct node_data{ int data; struct node_data * next; } list_data; ____ ____ ____ ____ ____ ____ ____ ____ ____ ____ list_data *d = -> | 1| -> | 2| -> | 3| -> | 4| -> | 5| -> | 6| -> | 7| -> | 8| -> | 9| -> |10| -> NULL If I want to get value of array_data on index 6, I'll

How do I implement SelectionSort and InsertionSort on a linked list in Python?

我们两清 提交于 2019-12-08 08:04:31
问题 I've implemented a Linked List class and I have a selectionSort and insertionSort function created that works on regular lists. I need to get selectionSort and insertionSort to work on linked lists, but I'm not sure where to even start, if I'm being honest. Here's my linked list class: class Node: def __init__(self, initdata): self.data = initdata self.next = None def getData(self): return self.data def getNext(self): return self.next def setData(self,newdata): self.data = newdata def setNext

Recursive Stack in C

问题 during recursion a stack is created what does that stack contains, does it contains the values or it stores the addresses of the operands void recursiveReverse(struct node** head_ref) { struct node* first; struct node* rest; /* empty list */ if (*head_ref == NULL) return; /* suppose first = {1, 2, 3}, rest = {2, 3} */ first = *head_ref; rest = first->next; /* List has only one node */ if (rest == NULL) return; /* reverse the rest list and put the first element at the end */ recursiveReverse(

C++ - Stack Pop() Function with Singly Linked list

佐手、 提交于 2019-12-08 07:13:03
问题 For starters this is apart of my current homework assignment for my Data Structures class. I am not asking for answers, I am asking for help. I have a stack class that is implementing a Linked List instead of an array. I am currently trying to write my pop() function. I have a node for my theBack part of the stack. I am just confused as to getting to the predecesor of my theBack node. Any help with this would be awesome! Thanks! 回答1: A stack is actually reasonably simple to implement as a

How do I make a deep copy in a constructors initialization list. c++

问题 This is the constructor for node in list class. I need to make a deep copy of winery, an other class in the initialization list. Item is an instance of winery. List::Node::Node(const Winery& winery) : item(winery) // your initialization list here { Winery w = winery; item = w; } constructor for winery: Winery::Winery(const char * const name, const char * const location, const int acres, const int rating) : name(name), location(location), acres(acres), rating(rating) { char *nm = new char

Java: How to check if a string is a part of any LinkedList element?

会有一股神秘感。 提交于 2019-12-08 06:09:08
问题 Okay so I have a LinkedList, and I have a String. I want to check if the String is contained within any of the LinkedList elements. For example: String a = "apple"; String listelement = "a bunch of apples"; LinkedList list = new LinkedList(); list.add(listelement); if(list.containsany(a){ System.out.println("Hooray!"); } Would result in printing "Hooray!" Obviously list.containsany isn't a real LinkedList method, I'm just using it for this purpose. So how can I simulate my example? Thanks 回答1

Javascript Link List reference

问题 I wanted to create a Linked List object in Javascript and I try to reverse it. I assume this is a really simple question, but I somehow got stuck. Here is my code. var Node = function (val) { this.value = val; this.next = null; }; var LinkList = function (node) { var head = node; function append(val) {...}; //works fine function toString() {...}; //works fine function reverse() { if (!head.next) { return; } var prev = head; var cur = head.next; while (cur) { var temp = cur.next; cur.next =
