Answers

Answer 1

Case 1: a1 ⊆ a2 ⊆ a3

The value of ja1 [ a2 [ a3j cannot be determined in this case because it could be any number between 1,000 and 100,000.

what is set?

Data structures known as sets are used in computer science to hold groups of unique components. Sets' elements cannot be placed in a certain sequence since they are unordered. Sets are widely used in procedures to test for set inclusion or to check for the availability of specific members. Sets are frequently used to hold collections of related data. In addition, sets can be used to hold data from operations, such as a collection of prime integers. Hash tables, binaries trees, or other data formats are frequently used in the implementation of sets. Graphs and relations are two examples of mathematical ideas that can be modelled or described using sets. Languages for programming frequently employ sets.

Write a modular program that accepts up to 20 integer test scores in the range of 0 to 100 from the user and stores them in an array. Then main should report how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function to help it. Hint: Have the program count the scores as they are entered. Your program may need this information later.

Answers

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static int countPerfect(int [] scores, int n){

    int count = 0;

    for(int i = 0;i<n;i++){

     if(scores[i] == 100) {count++;}  }

 return count; }

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int n;

 System.out.print("Number of scores: ");

 n = input.nextInt();

 if(n<1 || n>20){n=20;}

 int [] scores = new int[n];

 for(int i = 0;i<n;i++){

     scores[i] = input.nextInt();  }

 System.out.print("Perfect Scores: "+countPerfect(scores,n));  

}

}

Explanation:

The countPerfect function begins here

public static int countPerfect(int [] scores, int n){

This initializes the count to 0

    int count = 0;

This iterates through the array elements

    for(int i = 0;i<n;i++){

If current score is 100, count is incremented by 1

     if(scores[i] == 100) {count++;}  }

This returns the value of count

 return count; }

The main begins here

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

This declares the number of scores, n

 int n;

Prompt to enter the number of scores

 System.out.print("Number of scores: ");

This gets input for n

 n = input.nextInt();

If input is less than 1 or greater than 20, n is set to 20

 if(n<1 || n>20){n=20;}

This declares the scores as an array

 int [] scores = new int[n];

This iterates through the array and get inputs for each score

 for(int i = 0;i<n;i++){

     scores[i] = input.nextInt();  }

This calls the function and print the number of perfect scores

 System.out.print("Perfect Scores: "+countPerfect(scores,n));  

}

Answer:

I would select Straight 2-way Merge sort over Quicksort when:

C. If space were not an issue If I knew the size of the data set was very large.

Explanation:

For large datasets, the Straight 2-way Merge sort has been found to be more efficient than the Quicksort.  It also works faster than Quicksort.  However, Quicksort has been found to be more efficient, working faster than the Straight 2-way Merge sort with small datasets.  The two are algorithms for sorting.  While Straight 2-way Merge Sort uses two streams with repetitions, the Quicksort uses just one stream without repetitions and additional storage space.

Parts arrive at a two-machine system according to an exponential interarrival distribution with mean 20 minutes. Upon arrival, the parts are sent to Machine 1 and processed. The processing-time distribution is TRIA (4.5, 9.3, 11) minutes. The parts are then processed at Machine 2 with a processing-time distribution as TRIA (16.4, 19.1, 20.8) minutes. The parts from Machine 2 are directed back to Machine 1 to be processed a second time (same processing-time distribution but an independent draw from it). The completed parts then exit the system.

Answer:

UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4

Explanation:

Required

Write an update statement

The question is incomplete as the table name is not given.

So, I will make the following assumptions.

Table name = Vendors

So, the update statement is:

UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4;

The above statement queries the vendors table and changes the address  of vendor_id 4 from the initial value to Ste 260

Write the mostValuableNeighbor method, which compares the item in row r and column c to the items to its left and to its right. The method determines which of the three items has the greatest value and returns its name. If more than one of the values have a value that is greatest, then any of their names can be returned. If the item has no item to its left, it is compared only to the item to its right. If the item has no item to its right, it is compared only to the item to its left.

Answers

Answer:

Explanation:

The following method is written in Java, using the Item class and ItemGrid class found online we can use this method to grab the 2-dimensional array and compare the three neighbors in the same row. It saves the position of the neighbor with the greatest value in the variable greatest and then uses that position to call the getName() method from the object in that position to get the name of that Neighbor and returns the name.

public String mostValuableNeighbor(ItemGrid grid, int r, int c) {

       int greatest = grid[r][c];

      if (grid[r][c+1].getValue() > greatest.getValue()) {

          greatest = grid[r][c+1];

      }

       if (grid[r][c-1].getValue() > greatest.getValue()) {

           greatest = grid[r][c-1];

       }

       

      return greatest.getName();

   }

In this exercise we have to use the knowledge of computational language in JAVA to write the code.

We have the code in the attached image.

The code in Java can be found as:

public String mostValuableNeighbor(ItemGrid grid, int r, int c) {

      int greatest = grid[r][c];

     if (grid[r][c+1].getValue() > greatest.getValue()) {

         greatest = grid[r][c+1];

     }

      if (grid[r][c-1].getValue() > greatest.getValue()) {

          greatest = grid[r][c-1];

      }

     return greatest.getName();

  }
