an_is a sepuence of precise instructions which result in a solution
Answer:
algorithm.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
Furthermore, the processing symbols and their functions used in developing an algorithm are oval (start or stop), diamond (decision-making), circle (on-page connector), parallelogram (input and output), rectangle (calculation), arrow (flow or direction) and pentagon (off-page connector).
Some of the characteristics of an algorithm include the following;
I. An algorithm can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. An algorithm can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
In conclusion, an algorithm is a sequence of precise instructions which result in a solution for solving problems using a computer system.
I just need some help working out this Java code! I can list the instructions below:
Modify the CountSpaces program so that contains a String that holds your favorite inspirational quote. Pass the quote to the calculateSpaces method and return the number of spaces to be displayed in the main method.
We're given this to start however I have been struggling as there are two classes and it's been confusing me. Thanks so much for any help! All good and God Bless!
public class CountSpaces
{
public static void main(String[] args)
{
// write your code here
}
public static int calculateSpaces(String inString)
{
// write your code here
}
}
Answer:
public class CountSpaces
{
public static void main(String[] args)
{
String quote = "The concept of infinity is meaningless inside of an insane human mind.";
int nrSpaces = calculateSpaces(quote);
System.out.println("Nr spaces in your quote is " + nrSpaces);
}
public static int calculateSpaces(String inString)
{
int count = 0;
for (int i = 0; i < inString.length(); i++) {
if (inString.charAt(i) == ' ') {
count++;
}
}
return count;
}
}
Explanation:
In this example there is only one class, and since all methods are static the true concept of the class is not even being used.

Programming Exercise 11 in Chapter 8 explains how to add large integers using arrays. However, in that exercise, the program could add only integers of, at most, 20 digits. This chapter explains how to work with dynamic integers. Design a class named largeIntegers such that an object of this class can store an integer of any number of digits. Add operations to add, subtract, multiply, and compare integers stored in two objects. Also add constructors to properly initialize objects and functions to set, retrieve, and print the values of objects. Write a program to test your class.
Answer:
Explanation:
The following is written in Java. It creates a class called largeIntegers that creates objects of the built-in BigInteger class to handle operations on very large numbers. The class contains the add, subtract, multiply, compare, toString methods as well as the getter and setter method for the BigInteger. A test class has been provided and the output can be seen in the attached picture below where two numbers are created and added together. Due to technical difficulties, I have added the code as a txt file below.

of the following potential benefits, which is LEAST likely to be provided by the upgraded system?
A Human representatives will not be needed to respond to some inquiries.
B
The company will be able to provide a human representative for any incoming call.
с
Customers are likely to spend less time listening to information not relevant to their issue.
D
Customers will be unable to mistakenly select the incorrect department for their particular issue.
Answer:
The company will be able to provide human representative for any incoming call
Explanation:
The upgrade of a system is meant to resolve identified issues in an initial system and given that the available human representative is usually less than the number of incoming call at a given time, due to a constant drive for a larger customer base, we have;
The upgraded system will provide technologies such that human representative will not be required for some inquiries, customers will listen to mainly relevant information with regards to their issues and customers will be properly directed to the correct department that are concerned with their current issue
Therefore, the LEAST likely goal of the upgraded system from among the options and therefore the least likely to be provided by the upgrade is the company will be able to provide human representative for any incoming call

. Create a java File call Sales.Java contains a Java program that prompts for reads in the sales for each of 5 salespeople in a company. It then prints out the id and amount of sales for each salesperson and the total sale. 2. Compute and print the average sale. 3. Find and print the maximum and minimum sale. 4. After the list, sum, average, max and min have been printed, ask the user to enter a value. Then print the id of each salesperson who exceeded that amount, and the amount of their sales. Also print the total number of salespeople whose sales exceeded the value entered. 5. Instead of always reading in 5 sales amounts, in the beginning ask the user for the number of sales people and then create an array that is just the right size. The program can then proceed as before
Answer:
The program is as follows:

Scanner input = new Scanner(System.in);
int salesPeople;
System.out.print("Number of Sales People: ");
salesPeople = input.nextInt();
int[] salesID = new int[salesPeople];
float[] salesAmount = new float[salesPeople];
float total = 0;
for(int i = 0; i<salesPeople;i++){
System.out.print("ID: "); salesID[i] = input.nextInt();
System.out.print("Amount: "); salesAmount[i] = input.nextFloat();
total+=salesAmount[i]; }
System.out.println("ID\t\tAmount");
for(int i = 0; i<salesPeople;i++){
System.out.println(salesID[i]+"\t\t"+salesAmount[i]); }
System.out.println("Total Sales: "+total);
System.out.println("Average Sales: "+total/salesPeople);
Arrays.sort(salesAmount);
System.out.println("Minimum Sales: "+salesAmount[0]);
System.out.println("Maximum Sales: "+salesAmount[salesPeople-1]);
float sales;
System.out.print("Print records that exceed: "); sales = input.nextFloat();

describe what impact your personal vision could have your community or on society
My personal vision will have a positive impact on my community by solving the problems around my community and my society at large.
What is a personal vision?A personal vision is a written description of your goals, strengths, and ambitions. It could perhaps be oriented towards one's long-term aspirations and could be focused on life or career goals.
As an educationist, my vision, persistence, and determination to study stem from a desire to excel in my work as an educator, as well as to inspire and serve as a role model for my community and the world at large.
Growing up in a typical setting taught me about the effects of educational reform on livelihood, economics, environment, and human existence. I learned as a youngster the bad consequences of not being educated and being illiterate owing to the fact that people cannot just afford the high cost of learning.
Since then, I've dedicated my life to educating the public and teaching students in my community and society as a whole. My vision is to raise awareness of the negative consequences of illiteracy in our society and to promote action to combat it by giving free education to students and the general public.
