Given the rооt оf а binаry seаrch tree and an integer k, return true if there exist two elements in theBST such that their sum is equal to k, or false otherwise. 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 CasesInput: root = [5,3,6,2,4,null,7], k = 9 Output: true ContextWe use an unordered set seen to keep track of the values we’ve encountered. We can count the numberof occurrences of a value using seen.count(val) and we can insert new values using seen.insert(val).We have the findTarget function as follows bool findTarget(TreeNode* root, int k) {seen.clear(); // Clear the set before startingreturn findTarget(root, k);} which traverses the tree. Questions (2 pts)What should be the base case of the recursive findTarget function? (3 pts)We can check another condition (using seen.count()) that would return True if satisfied.Write the code for the condition in C++. (3 pts)Inside the recursive findTarget function, we insert the current node’s value in the set seenand make further recursive calls for the left subtree and right subtree. Write down the recursivecalls in C++. (3 pts)We can return True if either of the recursive calls returns True. Write the code for thisreturn value in C++. (2 pts)Should we follow postorder, preorder, or inorder traversal for this problem? Explain. (2 pts)What is the time and space complexity of this approach? Explain.
