Every added leaf should have a label ofv. If the node at this depth has existingbranches, you should add these leaves to theend of that list of branches.For example, you should be adding 1 leaf withlabel v to each node at depth 1, 2 leaves toeach node at depth 2, and so on.Here is an example of a tree t (shown on theleft) and the result after add_d_leaves isapplied with v as 5.323244555Hint: Use a helper function to keeptrack of the depth!def add_d_leaves(t, v):"""Add d leaves containing v to each ng def add_d_leaves(t, v):"""Add d leaves containing v to each nc>>> t_one_to_four = Tree(1, [Tree(2), 1>> print(t_one_to_four)134>>> add_d_leaves(t_one_to_four, 5)>> print (t_one_to_four)135>>> t1 = Tree(1, [Tree(3)])> add_d_leaves(t1, 4)>>> t1Tree(1, [Tree(3, [Tree(4)])])>> t2 = Tree(2, [Tree(5), Tree(6)])>> t3 = Tree(3, [t1, Tree(0), t2])>>> print(t3)3>>> add_d_leaves(t3, 10)>>> print(t3)3341010101010101010106101010"*** YOUR CODE HERE ***"

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.

Create a function that rapidly identifies whether any two nodes u and v in a tree T with s as the root node are ancestors or descendants of each other.
1.111.Q_7a. A path in a binary tree is a sequence of nodes where each pair of adjacent nodes in the sequence has an edge connecting them. A node can only appear in the sequence at most once. Note that the path does not need to pass through the root. The path sum of a path is the sum of the node's values in the path. Given the root of a binary tree, return the maximum path sum of any non-empty path .Input: root = [1,2,3] Output: 6 Explanation: The optimal path is 2 -> 1 -> 3 with a path sum of 2 + 1 + 3 = 6..tahms.
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)…

Code in C++ only In a rooted tree, the lowest common ancestor (or LCA for short) of two vertices u and v is defined as the lowest vertex that is ancestor of both that two vertices. Given a tree of N vertices, you need to answer the question of the form "r u v" which means if the root of the tree is at r then what is LCA of u and v. Input: 4 12 23 14 2 142 242 Output: 1
