Given the rооt оf а binаry tree аnd a desired integer sum, write a function with the appropriate header/signature in pseudocode or C++ code that determines if there exists a subtree whose sum of nodes equals the given desired sum. Also, state and justify the worst case time complexity of your solution in terms of Big O. Example: Input: Root and 18 (desired sum) Output: true Explanation: The return value of the method is true since the subtree at node 7 sums to 18 Assume the node class and a tree are already built for you. class TreeNode { int val; TreeNode *left; TreeNode *right; TreeNode(int x) : val(x), left(nullptr), right(nullptr) {} }; Rubric: Logic: 6 points Function signature and appropriate return value: 1 point Readability: 1 point Time Complexity and explanation: 2 points
