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

python: In a binary search tree, write another way of 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): root=p def helper(root, l, r): if not root: return True if not (left<root.val and root.val<right): return False return helper(root.l, l, root.val) and helper(root.r, root.val, r) return helper(root, float('-inf'), float('inf'))

C++ please Please complete Programming Exercise 4, from pages 1402, from chapter 19 from your textbook. Write a function, singleParent, that returns the number of nodes in abinary tree that have only one child. Add this function to the classbinaryTreeType and create a program to test this function. (Note: Firstcreate a binary search tree.)

Create a function that takes an array that represent a Binary Tree and a value and return true if the value is in the tree and, false otherwise. Examples valueInTree (arr1, 5) valueInTree (arr1, 9) valueInTree (arr2, 51) - true 1 false false
In JAVA code Write an algorithm for deleting a node of a Binary Search Tree. Take note that the Binary Search Tree property must be satisfied after a node is removed from a Binary Search Tree.
You have a large data set of an area with income and number of people having that income. You want to create an efficient search system using Binary Search Tree (BST) to search an income and related count. Input to be read from in.txt file, Consider a file (you have to create in.txt file and copy the sample data shown below) with total number of people (N) in the first line and next N lines will contain the income and corresponding count separated by space. Output: display the result in console. Do not spend too much time to produce exact output format as we will check the output manually. Tasks: [you have to write a set of functions and test them. Some of them are fairly small] 1. Create a binary search tree based on the income as the key. However, you should also store the corresponding count within the BST node. 2. Print the data in the tree in the inorder traversal to see the keys are in sorted order. Print them like comma separated tuple (income, count). (income, count)..... 3.…
Question 5: Add Leaves Implement add_d_leaves, a function that takes in a Tree instance t and mutates it so that at each depth d in the tree, d leaves with labels v are added to each node at that depth. For example, we want to add 1 leaf with v in it to each node at depth 1, 2 leaves to each node at depth 2, and so on. Recall that the depth of a node is the number of edges from that node to the root, so the depth of the root is 0. The leaves should be added to the end of the list of branches. def add_d_leaves(t, v): """Add d leaves containing v to each node at every depth d. > > > t1 = Tree(1, [ Tree(3)]) > > > add_d_leaves(t1, 4) > > > t1 Tree(1, [Tree(3, [Tree(4)])]) > > > t2 = Tree(2, [Tree(5), Tree (6)]) > > > t3 = Tree(3, [t1, Tree(0), t2]) > > > add_d_leaves (t3, 10) > > > print(t 3) 3 1 3 4 10 10 10 10 10 10 0 10 2 5 10 10 6 10 10 10 """ def add_leaves(t, d): "*** YOUR CODE HERE **** add_leaves (t, 0)
