Consider the following definition for an n-ary tree node. class Node {    public:        int value;        std::vector children;       Node (int value){           this->value = value;        }        void addChild(Node* child){            this->children.push_back(child);        }}; A sum tree is an n-ary tree of positive integers such that for any non-leaf node, its value is the sum of all values for the subtree rooted at said node. We consider null nodes to have a value of zero, and define an empty tree to be a valid sum tree.For instance, the following is a valid sum tree.While the tree depicted below is not. Namely, the node with the value of 7 is not the sum of the values of the nodes of its subtree, nor is the node with the value 48, or in turn the root with value 129. Problem Statement: Given the root of an n-ary tree write a function using pseudocode or C++ code that takes as input a prebuilt n-ary tree and returns a boolean that signifies if the tree is a valid sum tree. Have your algorithm output `true` if the tree is a valid sum tree or `false` otherwise.  In the text entry box, please switch from Paragraph mode to Preformatted mode to make your answer easier to read.
