In whаt оrder wоuld DFS prоcess the vertices of the grаph below when stаrting at vertex g?Assume that we follow the alphabetical order when considering the neighbors of a given node. (e.g.for 2 nodes m and n, m will be traversed before n). Show all the steps. The first step is shown below.1. Call stack: gTraversal order: (null)  

Yоu аre given the rооt of а full binаry tree with the following properties: Leaf nodes have either 0 or1, where 0 represents False and 1 represents True. Non-leaf nodes have either the value 2 or 3, where2 represents the boolean OR and 3 represents the boolean AND.The evaluation of a node is as follows: If the node is a leaf node, the evaluation is the node’s value,i.e. True or False. Otherwise, evaluate the node’s two children and apply the boolean operation of itsvalue with the children’s evaluations. Return the boolean result of evaluating the root node using arecursive function evaluateTree(). A tree node is defined as follows struct TreeNode {int val;TreeNode *left;TreeNode *right;TreeNode(int x) : val(x), left(nullptr), right(nullptr) {}};Example Test CaseTreeNode* root = new TreeNode(2); // ORroot->left = new TreeNode(1); // Trueroot->right = new TreeNode(3); // ANDroot->right->left = new TreeNode(0); // Falseroot->right->right = new TreeNode(1);Bool result= evaluateTree(root)// returns True     Questions   (3 pts) Assume the recursive function evaluateTree(TreeNode* root) evaluates its left andright subtrees recursively before applying any boolean operation OR or AND according to the valueof the node. What should be the base case for such a recursive function? Write the code in C++.Hint: For the base case, we return the value of a leaf node. What can be the value of a leaf node? (3 pts) Which traversal resembles the fact that “we evaluate a node’s left and right subtreesrecursively before applying any boolean operation OR or AND according to the value of thenode”? Explain. (4 pts) How do we know whether to apply OR or AND according to the value of a node? Get theresult of evaluating subtrees recursively and applying the boolean operations in C++.  (2 pts) Do you need to maintain a separate boolean variable for evaluating the tree? Explain. (3 pts)What is the time and space complexity for this approach? Justify your answer. Imagineyou have a total of n nodes and the tree’s height is h
