Needs to be answered using Dr. Racket (R5RS) language. Only Dr. Racket language (R5RS) scheme. NoJava or C++.Question: Define a SCHEME procedure, named (bfs T)which traverses a binary tree in BFS order andproduces a list of the values of the nodes of the tree in the order in which the nodes were "visited."5. Another traversal order visits a nodes children before visiting their children (i.e. the node'schildren's children). This traversal ordering is referred to as Breadth-First Search (BFS)order and is shown in Figure 3. Again, since we are working explicitly with binary trees,there are no cycles in our "graph" and we can safely neglect to record which nodes havebeen visited already by our algorithm.8.Figure 3: A binary tree showing the order in which nodes are visited in a BFS traversal as thevalue at each node.To implement a function showing BFS traversal of a tree, we use a Queue ADT. In thiscase, the root node is enqueued into the Queue ADT. Next, a node is dequeued, that node'schildren are enqueued into the queue ADT, and finally the value at the dequeued node isadded to the front of the list obtained by visiting the rest of the nodes in the queue. SeeAlgorithm 3.

In Haskell, how do you update a value of a particular node in a binary tree? Consider each node having a (Key,Value) tuple (where all keys are unique). Given an already existing key and its new value, I want to update the value of the key in the binary tree. Kindly provide Haskell code with an example.
Using your knowledge in binary tree traversals, implement the following tree traversing algorithms in either Java or C++, i. inorder, ii. preorder iii. and postorder traversal
Create an implementation of a binary tree using the recursive approach introduced in the chapter. In this approach, each node is a binary tree. Thus a binary tree contains a reference to the element stored at its root as well as references to its left and right subtrees. You may also want to include a reference to its parent.
Create a bottom-up insertion technique based on the same recursive approach, a red-black representation, and balanced 2-3-4 trees as the underlying data structure for an implementation of the fundamental symbol-table API. Only the sequence of 4-nodes (if any) at the bottom of the search path should be split by your insertion technique.
In C++, develop an algorithm that inserts the value val into a binary search tree with root. If the tree is empty, root = null. The algorithm returns the root of the tree containing the added item. You should assume that “new node” creates a new node with data field data and reference fields left (for left child) and right (for right child).
Explain the concept of a trie (prefix tree) and its use in implementing dictionaries. Provide an algorithmic description of how a trie can be constructed and searched efficiently.
Java - The depth of a heap or B-tree is never more than O(logN), so operations on these structures are also O(logN). True or false?
Write a program in c++ to do the following operations on a Binary Search Tree (BST) considering the inputs are a set of strings that represent the names of 12 months of a year (in the order of January, February, . . ., December). i) Print the successor and predecessor of any given node. ii) Search a particular string is present in the BST or not. iii) Delete any string from the BST.
Write a program in C++ to do the following operations on a Binary Search Tree (BST) considering the inputs are a set of strings that represent the name of 12 months of a year (in the order January, February,. . ., December). i) Create a BST and add one by one string where each string represents the name of a month. ii) Print the inorder, pre-order, and post-order traversal of the BST. iii) Print the minimum and maximum value strings among all the strings after the creation of the entire BST. Here, minimum and maximum values decided based on the alphabetical order of the strings. (For, example: Among January, February and March, ‘February is minimum value of the string and ‘March’ is the maximum value of string.)
