So I have a simple snippet of C++ code which is SUPPOSED to insert a node into a binary search tree. It returns true if the value is successfully inserted and false if the value is already in the tree. struct Node { int data; Node* parent = nullptr; Node* left = nullptr; Node* right ..

ListNode Code : template <typename T> struct ListNode { public: T data; ListNode *prev, *next; ListNode() { prev = nullptr; next = nullptr; } ListNode(T Data, ListNode *Prev, ListNode *Next) { data = Data; prev = Prev; next = Next; } }; Doubly LinkedList Code : #include <iostream> #include <stdexcept> using namespace std; template <typename ..
I just started learning c++ and I am working on an assignment asking us to build queue using linked list, but when I tried my "display function" I got an Thread 1: EXC_BAD_ACCESS (code=EXC_I386_GPFLT) error, my logic behind this function is that little arrow(->) is to dereference pointers, so in theory it should be able ..
I am trying to run a react project in my Windows environment but It’s throwing the following error. Before, this project worked on Ubuntu with the same things. It started to happen after I changed the OS. How can I fix this? I am just running npm start command. > REACT_APP_VERSION=$npm_package_version react-scripts -r @cypress/instrument-cra start ..
I’m having the following classes: template<typename T> class t_node { public: t_node* parent, * left, * right; int key; public: t_node(int key, t_node* parent = nullptr) :key(key), parent(parent), left(nullptr), right(nullptr) {} }; class node : public t_node<node> { public: node(int key, node* parent = nullptr) :t_node(key, parent) {} }; I want to inherit multiple node ..
I have implemented a method to insert a new node before a specific node. #ifndef FORWARD_SINGLY_LINKED_LIST_H #define FORWARD_SINGLY_LINKED_LIST_H #include <cstdlib> #include <string.h> #include <iostream> namespace forward_singly_linked_list { typedef struct Node { std::string data; struct Node *nextPointer; } Node; typedef Node *NodeP; class LinkedList { private: int elementsCount; Node *head; public: LinkedList() { head = NULL; ..
So i’m trying to implement a binary search tree and avl tree. Each of these classes using different but similar types of nodes. The classes for nodes look like this: class node { protected: int key; node* parent, * left, * right; public: node(int key, node* parent = nullptr) :key(key), parent(parent), left(nullptr), right(nullptr) {} ~node() ..
#include<bits/stdc++.h> using namespace std; // Linked List Node class Node { public: int data; // Data Node *next; // Pointer Node(int x) { data=x; next=NULL; } }; void append(Node **head, int val) { Node temp; if(head==NULL) { head=new Node(val); temp=head; } else { temp->next=new Node(val); temp=temp->next; } } // This function prints contents of linked ..
I think I know the bug is in the code wriiten inside the loop but I don’t know how to fix it. Please help me if I haven’t written the correct code to insert the child nodes appropriately in the Family-tree, or if a condition is missing due to which the loop runs infinitely. Here’s ..
I hope you all are having a wonderful day. Just to give. a little context, I am trying to make a Mancala game in C++. I’m still a beginner to coding and to this site, so my code may look weird. I am working on moving my pieces in the game and trying to implement ..
