Answer:
For values when n<32 use fb(n) else use fa(n).
See explaination for details
Explanation:
Earlier when n=1 fa(n)=2000 while fb(n)=2. for n=2 fa(n)=2000*22 =2000*4=8000 while fb(n)=2*24=2*16=32. It is observed that fa(n) requires more time than fb(n) for small values.
Now, we will see when fb(n) crosses fa(n). This can happen only when fb(n) values equals or greater than fa(n)
therefore,
2000n2<=2n4
Solving equation we get n2>=1000 which can happen when n>=32.
So for values when n<32 use fb(n) else use fa(n)
 
        
             
        
        
        
The S3 encryption, <u>Server-Side Encryption with Customer-Provided Keys (SSE-C)</u>, allows the company to leverage Amazon S3 for storing data with given constraints. 
What do you mean by S3 encryption?
S3 encryption <u>encrypts your </u><u>data </u><u>when it is written to disks in its </u><u>data </u><u>centers at the </u><u>object </u><u>level and decrypts it for you when you </u><u>access </u><u>it.</u> There is no distinction between accessing encrypted or unencrypted items as long as you authenticate your request and you have access permissions. 
S3 encryption<u> </u><u>encrypts an item before saving it to disk when you use server-side </u><u>encryption</u><u>; the </u><u>object </u><u>is then decrypted when you download the object</u>. S3 encryption lets you safeguard the data you store in AWS S3 buckets online, which is crucial for sensitive data.

Answer:
<u>Window.java</u>
- public class Window {
-     int width;
-     int height;
- 
-     public Window(int width, int height){
-         this.width = width;
-         this.height = height;
-     }
-     public int getWidth(){
-         return width;
-     }
-     public int getHeight(){
-         return height;
-     }
- 
-     public int getClientAreaHeight(){
-         return getHeight();
-     }
- }
<u>Main.java</u>
- public class Main {
-     public static void main (String [] args) {
-         Window win1 = new Window(12, 15);
-         System.out.println(win1.getClientAreaHeight());
-     }
- }
Explanation:
<u>Window.java</u>
There is a Window class with two int type attributes, width and height (Line 1 - 3). 
The constructor of this class will take two inputs, width and height and set these input to its attributes (Line 5 - 8). There are two methods getWidth and getHeight which will return the value of attributes width and height, respectively (Line 10 - 16). 
The required new method getClientAreaHeight is defined in line 18 -20. This method will call the getHeight method to return the height value of the window (Line 19). 
<u>Main.java</u>
We test the Window class by creating one Window instance and call the getClientAreaHeight method and print the return output (Line 1 -6).
We shall see 15 is printed.
