Chapter 21, Problem 25RQE
Program Plan Intro
Binary tree:
- It is a tree data structure which comes under hierarchical data structure.
- It is made of nodes that have a left child, right child and a data element.
Tree traversal:
- There are 3 common methods
- Inorder traversal
- Preorder traversal
- Postorder traversal
- In inorder traversal, the left subtree is encountered first, then data node and then the right subtree.
- In preorder traversal, the data node is encountered first, then left subtree and then the right subtree.
- In postorder traversal, the left subtree is encountered first, then right subtree and then the data node.

Double pointers: Describe how this operation can be done in O(1) time if there are pointers in each node to both the previous and the next node.
typedef struct node{int data;struct node *left,*right;}BST;The node structure of BST is shown above. Please design an efficient algorithm to return the maximum keyword value in BST. Completion function: int findmax (BST *T)
struct node{
int a;
struct node * nextptr;
};
Write two functions. One for inserting new values to a link list that uses the given node structure.
void insert(struct node **head, int value);
Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers.
int countEvenNumbers(struct node *head);
Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen.
Note 1: Do not modify the function prototypes.

If no number is found, returns -1. All cases must be handled. You can define any helper method as needed. #include #include #define INF INT_MAX // indicates infinity value using namespace std; struct Node int key; Node next; Node(int key) { this->key - key; this->next- NULL; }; class SinglyLinkedList public: SinglyLinkedList () head - NULL; void addFront (Node* node) 1 int remove(int val) { private: Node head; }; int main() { SinglyLinkedList sLL - neu SinglyLinkedList (); Node* nodel = new Node (5); Node node2 - neu Node (13); Node node3 - nev Node(7);…arrow_forward

Also, you need to implement the following functions: Insert Sorted LINKEDLIST insertSorted(LINKEDLIST head, int num): head points to the first node in the sorted linked list; num is a number to be inserted in in correct place in the linked list pointed at “head”. The linked list should be sorted after inserting “num”. This function returns the head of the modified head. BSTREE insert(BSTREE root, int num): root points to a node in a binary search tree; num is a number to be inserted in the tree rooted at “root”. This function returns the root of the modified tree. Find an element LINKEDLIST find(LINKEDLIST head,int num): head points to the first node of a linked list; num is a number to be searched for in the linked list started at “head”. This function returns a pointer to the node containing “num” or NULL if num is not found BSTREE find(BSTREE root,int…arrow_forwardBinary Search Tree Using a binary search tree, you are tasked with building a dictionary program which you can store a word with its definition. Each node of the tree will contain the word and definition. The word is what will be used as the key to sort our data. The dictionary should allow you to search for a word. If the word exist then the definition will display. You can also add words to the dictionary. For testing you should be able to display the current word list. The dictionary will populate from a data file and new words will be saved to the file as well. We are still covering Binary trees in class, but we have covered enough to get you started.arrow_forward
