<prompt> Kwa kuwa mizizi ya mti n-ary, kurudi baada ya utaratibu traversal ya maadili yake nodes . Nary-Mti input serialization ni kuwakilishwa katika kiwango cha utaratibu traversal yao. Kila kundi la watoto ni kutengwa na thamani sifuri. Andika ufumbuzi katika C .  <response>: Heres the C code to perform postorder traversal of an n-ary tree:class Node public: int val; vector children; Node Nodeint _val val _val; Nodeint _val, vector _children val _val; children _children; ;vector postorderNode root vector result; if root nullptr return result; Traverse all the children for Node child : root-children vector childValues postorderchild; result.insertresult.end, childValues.begin, childValues.end; Append the value of the root result.push_backroot-val; return result;Here, were performing a recursive postorder traversal of the n-ary tree. We first recursively traverse all the children of the node, and then append the value of the current node to the postorder traversal result.We start at the root of the tree, and keep calling the postorder function recursively on each child of the node. Once we have the postorder traversal of all the children, we simply append the value of the current node to the result vector and return it.
