Q4: Is BST Write a function is_bst, which takes a Tree t and returns True if, and only if t is a valid binary search tree, which means that: Each node has at most two children (a leaf is automatically a valid binary search tree) The children are valid binary search trees • For every node, the entries in that node's left child are less than or equal to the label of the node • For every node, the entries in that node's right child are greater than the label of the node

Need to answer in C language: Part 1: I need to define a binary search tree data structure and need to implement the following functions: Insert Sorted 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. Print Elements void inorderTraversal(BSTREE root, FILE *fp): root points to a node in a binary search tree. This function does not return anything, but prints out, to the file specified, the nodes in the tree rooted at “root” by performing an inorder traversal. Part 2: Test the performance of the designed data structure using theoretical and experimental approaches as follows: Dataset 1-Dataset is sorted- Add code to insert the numbers 1...n in that order in a binary search tree. Run it on different values of n where : n = 20,000 n = 50,000 n = 100,000 Do an in-order traversal of the tree, printing out the contents to a file…
Write a function f1 that takes the root of a binary tree as a parameter and returns thesum of the nodes which are in the right subtree of the root. You must not consider the valueof the root in the final sum.
All of the following are true EXCEPT: An empty tree is defined to have a height of 1. The depth of a node p is the number of ancestors of p, other than p itself. The height of a tree to be equal to the maximum of the depths of its nodes (or zero, if the tree is empty). The height of a node p in a tree T: • If p is a leaf, then the height of p is 0. • Otherwise, the height of p is one more than the maximum of the heights of p's children.

In the binary search tree, write a function that takes in a root, p, and checks whether the tree rooted in p is a binary search tree or not. What is the time complexity of your function? def is_bst(self, p: Node):
1. Create a Java program that prompts the user the initial choices for the Binary Search Treea. User chooses 1: Insert, User chooses 2: Delete, User chooses 3: Show BinaryTree, User chooses 4: Exit Program 2. Insertion in a tree should be such that it obeys the main properties of the binary searchtree. The basic algorithm should be:a. If the node to be inserted is greater than the existing root, move down a levelthrough the right pointer of the root.b. If the node to be inserted is lesser than the existing root, move down a levelthrough the left pointer of the root.c. Repeat this process for all nodes till the leaves are reached.d. Insert the node as the left or right pointer for the leaf (based on its value - if it issmaller than the leaf, it should be inserted as the left pointer; if it is larger than theleaf, it should be inserted as the right pointer) 3. Deletion is a bit more complicated than insertion because it varies depending on the nodethat needs to be deleted from the…

Create a function that quickly determines if two nodes u and v in a tree T with s as the root are ancestors or descendants.
Write the following functions: a) The function gets a root of a Binary Tree of ints, and a boolean predicate pred. It returns a pointer to a vertex v for which the data satisfies pred, i.e. pred(v->>data)==true. if no such vertex is not found, the function returns -1. If there are several such vertices, the function returns the first such v in pre-order . // finds the first node in pre-order satisfying pred // if such node not found, returns NULL BTnode_t* find(const BTnode_t* root, bool (*pred)(int)); struct BTnode { int value; struct BTnode*left; struct BTnode*right; struct BTnode*parent; }; typedef struct BTnode BTnode_t; BTNODE.C: BTnode_t* create_node(int val) { BTnode_t* newNode = (BTnode_t*) malloc(sizeof(BTnode_t)); newNode->value = val; newNode->left = NULL; newNode->right = NULL; newNode->parent = NULL; returnnewNode; } void set_left_child(BTnode_t* parent, BTnode_t* left_child) { if (parent) parent->left = left_child; if (left_child)…
