 Yоu аre wоrking оn а text editor аpplication that needs to handle large documents efficiently. The application should support frequent insertions and deletions of text at any position within the document. Which data structure would be the most suitable choice for this use case?

Given the rооt оf а binаry tree, return the level order trаversal of its nodes’ values. (i.e., from left toright, level by level). A tree node is defined as follows   struct TreeNode {int val;TreeNode *left;TreeNode *right;TreeNode(int x) : val(x), left(nullptr), right(nullptr) {}};   We initialize a vector and a queue as follows vector result;queue q;   Example Test Cases   Input: root = [5,3,6,2,4,null,7] Output: {{5}, {3, 6}, {2,4,7}}       Questions (8 pts) The skeleton of the levelOrder function is as follows vector levelOrder(TreeNode* root) {vector result;if (!root) return result;std::queue q;q.push(root);--------------BLOCK1--------------return result;In BLOCK 1, do the following -While the queue is not empty:– Get the number of nodes at the current level.– Initialize a list of the current level’s values.For each node at the current level:– Remove the node from the queue.– Add its value to the current level’s list.– Add its children to the queue if they exist.After processing the current level:– Add the current level’s list to the result.Write the code in C++. B. (3 pts) What is the space and time complexity of this approach? Assume the tree has n nodes   C.(4 pts) What is the worst-case time complexity of traversing a graph (with n nodes) where everynode is connected to every other node? Explain.

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.
