Instructions
Develop a java program that learns about a universe of your choice by asking the user yes/no questions.
Universe Knowledge Base
Develop a program that begins with minimal knowledge. When the program incorrectly guesses an answer, it asks for the answer and asks for a way to identify the item. The program builds a binary tree of questions and items. A YES response to a question is stored in the question’s left child while a NO answer is stored in the question’s right child.
