Expert Solution & Answer
Chapter 14, Problem 21E
Explanation of Solution
Given scenario:
- An attribute that stores values for names is taken, where:
- Maximum size of name can be as large as 40 characters.
- Average size is around 10 characters.
The given attribute will face two issues:
- Each name will be of different length.
- Names can be quite long as stated.
- It may result in low fan-out and a likewise increase in the height of the tree.
- Additionally, having variable length search keys will result in different nodes having different fan-outs, even if they are full.
- Prefix compression can be used to increase the fan-out of a node...

- 1. Create a Vehicle.java file. Implement the public Vehicle and Car classes in Vehicle.java, including all the variables and methods in the UMLS. Vehicle - make: String model: String -year: int + Vehicle(String make, String, model, int, year) + getMake(): String + setMake(String make): void + getModel(): String + setModel(String model): void + getYear(): int + set Year(int year): void +toString(): String Car - numDoors: int + numberOfCar: int + Car(String make, String, model, int, year, int numDoors) + getNumDoors(): int + setNumDoors (int num Doors): void + toString(): String 2. Create a CarTest.java file. Implement a public CarTest class with a main method. In the main method, create one Car object and print the object using System.out.println(). Then, print the numberOfCar. Your printing result must follow the example output: make Toyota, model=Camry, year=2022 numDoors=4 1 Hint: You need to modify the toString methods in the Car class and Vehicle class!arrow_forwardCHATGPT GAVE ME WRONG ANSWER PLEASE HELParrow_forwardHELP CHAT GPT GAVE ME WRONG ANSWER Consider the following implementation of a container that will be used in a concurrent environment.

- Write a C program using embedded assembler in which you use your own function to multiply by two without using the product. Tip: Just remember that multiplying by two in binary means shifting the number one place to the left. You can use the sample program from the previous exercise as a basis, which increments a variable. Just replace the INC instruction with SHL.arrow_forwardusing r languagearrow_forwardr languagearrow_forward
