I would select Straight 2-way Merge sort over Quick sort when which of the following are true.
A. Incorrect selections will be penalized.
B. If I knew that the distribution of the data was significantly skewed.
C. If space were not an issue If I knew the size of the data set was very large.
D. If I knew that the data tended to be in order.
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.

Design a program that asks the User to enter a series of 5 numbers. The program should store the numbers in a list then display the following data: 1. The lowest number in the list 2. The highest number in the list 3. The total of the numbers in the list 4. The average of the numbers in the list
Answer:
The program in Python is as follows:
numbers = []
total = 0
for i in range(5):
num = float(input(": "))
numbers.append(num)
total+=num
print("Lowest: ",min(numbers))
print("Highest: ",max(numbers))
print("Total: ",total)
print("Average: ",total/5)
Explanation:
The program uses list to answer the question
This initializes an empty list
numbers = []
This initializes total to 0
total = 0
The following loop is repeated 5 times
for i in range(5):
This gets each input
num = float(input(": "))
This appends each input to the list
numbers.append(num)
This adds up each input
total+=num
This prints the lowest using min() function
print("Lowest: ",min(numbers))
This prints the highest using max() function
print("Highest: ",max(numbers))
This prints the total
print("Total: ",total)
This calculates and prints the average
print("Average: ",total/5)

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.
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));
}
g Write an UPDATE statement that changes the address for the row with vendor_id 4 so the suite number (Ste 260) is stored in vendor address instead of vendor address 1. Then, use SQL Developer to verify the change (you may need to click the Refresh button at the top of the Data tab to see the change). If this works correctly, go back to the tab for the UPDATE statement and click the Commit button to commit the change.
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
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. Run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time with Arena Model

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.
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();
}

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of integers as input, and outputs the average and max.
Ex: If the input is:
15 20 0 5
the output is:
10 20
Answer:
Answered below
Explanation:
#python program
#First get the number of inputs from user
num_inputs = int(input("Enter number of inputs:")
j = 0
sum =0
max = 0
while j < num_inputs:
num = int(input ("Enter numbers: ")
sum = sum + num
if num > max:
max = num
j++
#Compute the average
average = sum/num_inputs
print (average, max)

The Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, ......., where each number is the sum of the two preceding numbers. Write a program that declares an array of length 15 and fills the array with the first 15 Fibonacci numbers. Print the array to check if the array elements are correct. Use the sizeofoperator instead of 15 whenever you need to use the array length.
Consider the following code snippet:
public static void print(E[] a)
{
for (int i = 0; i < a.length; i++)
{
System.out.println(a[i] + " ");
}
}
int[] a = {3,6,5,7,8,9,2,3};
print(makeArray(a));
Assume that the method call to print(makeArray(a)) works correctly by printing the int array a. Which of the following headers for the makeArray method will make this possible?
I public static Integer[] makeArray(int[] a)
II public static E[] makeArray(int[] a)
III public static Integer[] makeArray(E[] a)

What does it mean when the syntax ? extends D is used?
Any subclass of D may be used.
Any superclass of D may be used.
Any subclass or superclass of D may be used.
This indicates a wildcard with an upper bound.
Consider the following code snippet that declares the GraduateStudent class:
public GraduateStudent extends Student { . . .}
Which of these statements are false?
a. I GraduateStudent is a subclass of Student
b. II Stack is a subclass of Stack
c. III Stack is a subclass of Stack
d. II only
e. III only
f. II and III only
g. I only
Answer:
Explanation:
1) I and II only ... This is because the makeArray parameter must be an int[] since that is what the a array that is being passed actually is. The return type should be E[] only but since that is not an option, it could work with Integer[] if the E class allows.
2) Any superclass of D may be used. Although this is not complete, extends allows for a subclass to access any variables and methods within the superclass D but not directly access another superclass of D.
3) I only ... GraduateStudent is a subclass of Student
Reusing existing software to create a new software system or product can be a cost-efficient approach to development in many software projects. It may not be cost-efficient in all projects.
