<prompt> Kutokana na mizizi ya mti n-ary, kurudi kabla 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 Tazama mifano  <response>: To perform a preorder traversal on an n-ary tree, you can use a recursive approach where you visit the root node, then traverse each child from left to right, and apply the same process to each subtree. Here is an implementation in Python:class Node: def __init__self, valNone, childrenNone: self.val val self.children children if children else def preorderroot: if not root: return res res.appendroot.val for child in root.children: res preorderchild return resThis implementation assumes that the n-ary tree is represented by Node objects, where val contains the node value and children is a list of child nodes. The preorder function returns a list of node values in preorder traversal order.
