The COVID-19 pandemic situation has challenged the medical equipment supply chain leading to an uneven distribution of personal protective equipment (PPEs) at local hospitals. Assuming the following:

• These hospitals are represented as nodes (of type BSTNode) in a binary tree.
• There are N numbers of hospitals.
• There are N numbers of PPEs.
• Even distribution means each hospital receives 1 PPE (in a real situation, this 1 PPE can be 1 truckload of PPEs but we are using 1 PPE to simplify this problem).

3 1

/ \ -----> / \

0 0 1 1

For brevity, the above tree can be flattened level-order-wide in an array as [3,0,0]. The resulting tree is [1,1,1]. The above initial distribution requires TWO (2) moves to arrive at an even distribution with each node receiving 1 PPE, namely, 1 PPE going from root -> root. left, and another PPE from root -> root. right. You will start with the following code template.

Unlimited Attempts MISSING Your solution has to be platform-independent; it must run on any platforms including any online SUBMITTED IDEs: 1 Attempt View Feedback Next Up: Review Feedback You solution should be free of any use of packages. Example, absolutely no /* Java Program Example - Java Import Packages * package YOUR_CUSTOM_PACKAGE HERE; Your solution, regardless of how many classes it has, should be in one .java file. Your solution has to run on any online IDEs. If your solution fails the platform-independence criteria, you will have to resubmit work subject to the late penalty. The Late Work policy applies for all late submissions. Your solution should be reusable, meaning it will be invoked and validated against a series of input sequentially to produce consistent outcomes like so: Solution sol = new Solution(); sol.your_method1(test_input_1...); sol.your_method2(test_input_2 ...); PROBLEM 1 Try Again https://online.smc.edu/courses/38679/assignments/739873 1/5 5/8/2021 Homework Assignment #8 VIDEO DESCRIPTION HERE (https://cccconfer.zoom.us/rec/share/yvq8poxULRwC9smTbp0X31mFC_mmxZ6ydlYIewsnzeg5aj1M3qDVZ3o6ld91YOT.GVyjqNqsdaYzo5QH? startTime=1620099281000) ( 10 points ) The COVID-19 pandemic situation has challenged the medical equipment supply chain leading to an uneven distribution of personal protective equipments (PPEs) at local hospitals. Assuming the following: These hospitals are represented as nodes (of type BSTNode) in a binary tree. There are N number of hospitals. There are N number of PPEs. Even distribution means each hospital receives 1 PPE (in real situation, this 1 PPE can be 1 truck load of PPEs but we are using 1 PPE to simplify this problem). To solve the supply chain logistic, you are asked to write a quick software to output the number of moves required to evenly distribute PPEs amongst the hospitals such that each receives 1 PPE. For example you may have an initial distribution map looking like so: 3 1 /\ 0 0 -----> / \ 1 1 For brevity the above tree can be flattened level-order-wide in an array as [3,0,0]. The resulting tree is [1,1,1]. The above initial distribution requires TWO (2) moves to arrive at an even distribution with each node receiving 1 PPE, namely, 1 PPE going from root -> root.left, and another PPE from root -> root.right. You will start with the following code template.
