Problem 2 Write a method that (a) returns an int[] , (b) takes in two sorted arrays (in descending order) and (c) returns an int
Galina-37 [17]

Answer:

Following are the Program in the Java Programming Language.

//define class

public class Main

{

//define function to merge and sort array

public static int[] sort_Array(int[] a, int[] b)

{

//set integer variable and initialize values

int x = 0, y = 0, k = 0, num = 0;

int n = a.length;

int n1 = b.length;

//set integer type array

int[] ar = new int[n+n1];

//set while loop

while (x<n && y <n1)

{

num++;

num++;

//set if conditional statement

if (a[x] > b[y])

ar[k++] = a[x++];

else

ar[k++] = b[y++];

num++;

}

//set the while loop

while (x < n)

{

num++;

ar[k++] = a[x++];

}

//set the while loop

while (y < n1)

{

num++;

ar[k++] = b[y++];

}

//print the total compares done

System.out.println("Number of compares done: " + n);

//return array

return ar;

}

//define main method

public static void main(String[] args)

{

//declaration and the initialization of array

int[] a = new int[]{18,16, 15, 6, 2};

int[] b = new int[]{13, 12, 11, 7, 1};

int[] ar;

//call function

ar = sort_Array(a, b);

//print message

System.out.println("\nThe resultant array is: \n");

//set for loop to print array

for(int x=0; x<ar.length; x++)

{

System.out.print(ar[x] + " ");

}

}

}

<u>Output</u>:

Number of compares done: 5

The resultant array is:

18 16 15 13 12 11 7 6 2 1

Explanation:

Here, we define a class "Main" inside the class, define a function "sort_Array()"and pass two integer type array argument "a" and "b".

  • Set four integer type variables "x", "y", "k", and "num" and initialize them to 0.
  • Set two integer type array "n", "n1" and initialize them the length of the array then, set integer type array variable "ar".
  • Set the while loop then, set if conditional statement then, agin set while loop to sort array in descending order.
  • Then, print the number of compares and return the value of the variable "ar".

Finally, define the main method inside it, we set two integer type array variable and initialize elements in them then, set the for loop to print the sorted elements of the array.

What validation type would you use to check that numbers fell within a certain range? a) range check b)presence check c)check di
olga2289 [7]

Answer:

a) range check

Explanation:

Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.

Basically, there are five (5) main validation methods and these includes;

I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.

II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.

III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.

IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.

V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.

Hence, range check is a validation type you would use to check that numbers fell within a certain range.

For example, 0 < x > 1000 is a range check.

77julia77 [94]

The correct answer is centrifugal force.

The force that pulls out from the center on a body that is in a circular motion is called centrifugal force. This force increases as the speed of motion increases. It is centrifugal force that results in a strong outward pull on your vehicle traveling around a corner.

How does a barcode work?
Genrish500 [490]
A barcode's bars have 

1. different thicknesses, so they each signify 1 or 2 nibbles. 
2. the combinations of the thicknesses of those bars exceed the trillions. That's why manufacturers and stores never run out of SKU barcodes.
