1. What do you think are the main challenges and implications being faced regarding the changes in the service concept of KidZania, centered on experiential learning?
2. Considering the experience gained from all their current parks as well as the external forces including increasing competition, market regulations, diversity of potential new markets, and technology integration, what criteria should KidZania’s management follow in selecting specific activities for its future “cities” to enhance experiential learning while remaining profitable?

Lab-08: BinarySearchTree Implementation
Rules:
1. Allow Tester to iterate
through all nodes using the in-order traversal as the
default.
This
means, in Tester the following code should work for an instance of
this class
called bst
that is storing Student objects for the data:
BinarySearchTree_Lab08<String> bst = new
BinarySearchTree_Lab08<String>();
bst.add("Man");
bst.add("Soda"); bst.add("Flag");
bst.add("Home");
bst.add("Today"); bst.add("Jack");
for(String s : bst)
System.out.println(s);
2. You can not
use a size variable to keep track of the number of nodes

A report differs from an essay in that the Executive Summary is the introduction and conclusion in one.
|-------- Why something was done and why it is important
|-------- Purpose of the report (problem solving, feasibility, etc.).
|-------- Main findings and important recommendations.
The introduction and conclusion mentioned in the discussion section below are equivalent to the first and last stages of the main body of the essay.
Discussion Identify problem, position, possibilities, proposal Introduction
|-------- Background to the problem in detail. Review of pertinent issues from the literature. Proof and

Suppose that the average waiting time for a patient at a physician's office is just over 29 minutes. In order to address the issue of long patient wait times, some physicians' offices are using wait-tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wait times (minutes) for a sample of patients at offices that do not have a wait-tracking system and wait times for a sample of patients at offices with a wait-tracking system.

Create a program that creates a mini database of numbers that allows the user to: reset the database, print the database, add a number to the database, find the sum of the elements in the database, or quit.
In main, you will declare an array of 10 integers (this is a requirement). Then you will define the following methods: • printArray (int[ ] arr) – this takes in an array and prints it • initArray (int[ ] arr) – this initializes the array so that each cell is 0 • printSum (int[ ] arr) – this calculates the sum of the elements in the array and prints it • enterNum(int[ ] arr) – this asks the user for a slot number and value – putting the value into the array in the correct slot • printMenu (int[ ] arr) – prints the menu in the sample output (that’s it, nothing more)
In main, create an array of 10 integers and immediately call initArray( ). Then, continuously looping, print the menu and ask the user what they want to do – calling the appropriate methods based on the user’s choice. Note that every time you call a method, you must pass the array that was created in main. If it makes it easier, we used a do-while loop and a switch statement in main.
It should behave like the sample output below: (user input = bold)
