Hint: use a pattern match with three branches, where the expression being matched is a pair of trees. please use Ocaml for the codingDefine a function called get_predecessor() which takes a Node object and a value as parameters. The function should search the chain of nodes starting at the parameter node and returns the node which comes before the node containing the parameter value. If the parameter value is NOT in the chain of nodes or the parameter value is in the first node of the chain, the function returns None.

- Please c++ only. Correct answer will upvoted else downvoted. In this problem statement, tree is an undirected associated diagram where there are no cycles. This issue is about non-established trees. A leaf of a tree is a vertex that is associated with all things considered one vertex. The landscaper Vitaly grew a tree from n vertices. He chose to manage the tree. To do this, he plays out a number of tasks. In one activity, he eliminates all leaves of the tree. Note the uncommon instances of the activity: applying an activity to an unfilled tree (of 0 vertices) doesn't transform it. applying an activity to a tree of one vertex eliminates this vertex this vertex is treated as a leaf. applying an activity to a tree of two vertices eliminates both vertices (both vertices are treated as leaves). Vitaly applied k tasks successively to the tree. What number of vertices remain? Input :The main line contains one integer t (1≤t≤104) — the number of experiments.

- Write a class for implementing a simple binary search tree capable of storing numbers. The class should have member functions void insert(double x) bool search(double x)void inorder(vector <double> & v )The insert function should not use recursion directly, or indirectly by calling a recursive function. The search function should work by calling a private recursive member function bool search(double x, BtreeNode *t) The inorder function is passed an initially empty vector v: it fills v with the inorder list of numbers stored in the binary search tree. Demonstrate the operation of the class using a suitable driver program.Consider the following function:int mystery(NodeInt32* node){int counter = 0; while (node != NULL) {counter++;node = node->next; } return counter;}(a)The mystery function is recursive.A. True B. FalseA linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0. Example: head refers to the list of nodes 1 → 2 → 3 → 1 → NULL. There is a cycle where node 3 points back to node 1, so return 1. Function Description: Complete the has cycle function provided in the moodle assignment folder. It has the following parameter: • SinglyLinkedListNode pointer head: a reference to the head of the list. Returns: • int: 1 if there is a cycle or 0 if there is not. Note: if the list is empty, head will be null. Input Format: The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity.
