JAVA : Recursively complete the IsSemiBalanced() method using one helper function for a binary tree.
public class MyIntSET {
private Node root;
private static class Node {
public final int key;
public Node left, right;
public Node(int key) { this.key = key; }
}
// tree is semi-perfect if every node is semi-perfect
// A node with 0 children is semi-perfect.
// A node with 1 child is NOT semi-perfect.
// A node with 2 children is semi-perfect if (size-of-larger-child <= size-of-smaller-child * 3)
// hint: in the helper, return -1 if the tree is not semi-perfect, otherwise return the size
public boolean isSemiBalanced() {
// TODO
return false;
}
