Answer:

True.

Explanation:

the pivot element in quick sort is the the value of an element present in the array that is present in the array.The pivot is the most important element in the quick sort because the time complexity of the quick sort depends upon the pivot element.

If the pivot selected in the array is always the highest or the lowest element then the time complexity of the quick sort becomes O(N²) other wise the average time complexity of quick sort is O(NlogN).

  • If average score is between 66 and 75, the letter grade is B
  • If average score is between 56 and 65, the letter grade is C
  • If average score is between 46 and 55, the letter grade is D
  • If average score is between 40 and 45, the letter grade is E
  • If average score is lesser than 40, the letter grade is F

The program is written in Java and it uses comments to explain difficult lines. The program is as follows

import java.util.*;

public class Tests

{

public static void main(String [] args)

{

 //Declare variables

 Scanner input = new Scanner(System.in);

 String firstname, lastname;

 //Prompt user for name

 System.out.print("Enter Lastname: ");

 lastname = input.next();

 System.out.print("Enter Firstname: ");

 firstname = input.next();

 char grade;

 //Declare Array

 int[] Scores = new int[5];

 //Initialize total scores to 0

 int total = 0;  

  //Decalare Average

  double   average;

 //Prompt user for scores

 for(int i =0;i<5;i++)

 {

  System.out.print("Enter Score "+(i+1)+": ");

  Scores[i] = input.nextInt();

  //Calculate Total Scores

  total+=Scores[i];

 }

 //Calculate Average

 average = total/5.0;

 //Get Letter Grade

 if(average>75)

 {

 grade = 'A';

 }

 else if(average>65)

 {

 grade = 'B';

 }

 else if(average>55)

 {

 grade = 'C';

 }

 else if(average>45)

 {

 grade = 'D';

 }

 else if(average>40)

 {

 grade = 'E';

 }

 else

 {

 grade = 'F';

 }

 //Print Student Results

 System.out.print("Fullname: "+lastname+", "+firstname);

 System.out.print('\n');

 System.out.print("Total Scores: "+total);

 System.out.print('\n');

 System.out.print("Average Scores: "+average);

 System.out.print('\n');

 System.out.print("Grade: "+grade);

}

}

Question 17/20
babymother [125]

The process for maturing an idea towards patentability is called: CIM.

An intellectual property can be defined as an intangible and innovative creation of the mind that is solely dependent on human intellect (intelligence).

Hence, an intellectual property is an intangible creation of the human mind, ideas, thoughts or intelligence.

Globally, there are three (3) main ways to protect an idea or intellectual property and these include:

  • Trademarks.
  • Copyright.
  • Patents.

A patent can be defined as the exclusive (sole) right granted to an inventor by a sovereign authority such as a government, which enables him or her to manufacture, use, or sell an invention (idea) for a specific period of time.

Generally, patents are used on an idea or innovation for products that are manufactured through the application of various technologies.

CIM is an acronym for collaborative invention mining and it can be defined as the process for maturing an idea towards patentability, especially through collaborative interaction..

Thus, the objective of collaborative invention mining (CIM) is to collectively strengthen, mature and develop an idea to become a tangible product that proffers a solution to a problem, thereby, making it patentable.
