CS代考程序代写 Java public class Odd {

public class Odd {

public boolean isOdd(Node r) {
/* Input: Root r of a tree
Output: true if all internal nodes of the tree have odd degree; false otherwise

You can use the following methods from class Node:
– numChildren() returns the number of children of a node.
– isLeaf(): returns true if a node is a leaf and returns false otherwise

To translate the following pseudocode

for each child u of r do { … }

use the following java code:

Node[] children = r.getChildren();
for (Node u : children) { … }
