Answer:
See text attachment for complete source code (for the answer) where I used comments to explain each line of the program
Explanation:
First, design the form using the following tools (and the accompanying properties) :
1 Label: Property: Text: Score
2 Buttons
Button1: Property: Name: btnAdd; Text: Add
Button2: Property: Name: btnDisplay; Text: Display
1 ListBox: Property: Visible: Hidden
1 TextBox: Property: Name: txtNum1
First, create the following function.
The function (named typecheck) validates input from the user (i.e. integer input only)
Function typecheck(ByVal input As String) As Boolean
Try
Convert.ToInt32(input)
\(Return\ True\)
\(Catch\ ex\ As\ Exception\)
\(Return\ False\)
End Try
End Function
It returns true if the input is integer and false, if otherwise.
Next, double-click on the "Add" button and write the following lines of code:
Dim num1 As String
num1 = txtNum1.Text
If num1 IsNot String.Empty Then
If typecheck(num1) Then
\(ListBox1.Items.Add(num1)\)
\(txtNum1.Text = String.Empty\)
Else
\(MsgBox("Only\) \(Integer\) \(Inpu t")\)
\(txtNum1.Text = String.Empty\)
\(End\ If\)
Else
\(MsgBox("Box\) \(can\ not\ be\ empty")\)
\(txtNum1.Text = String.Empty\)
\(End\ If\)
Next, double-click on the "Display" button and write the following lines of code:
If ListBox1.Items.Count > 0 Then
\(Dim\ max1, max2\ As\ Integer\)
max1 = Convert.ToInt32(ListBox1.Items(0))
max2 = Convert.ToInt32(ListBox1.Items(0))
\(For\ count\ = 0\ To\ ListBox1.Items.Count - 1\)
If Convert.ToInt32(ListBox1.Items(\(count\))) >= max1 Then
max1 = Convert.ToInt32(ListBox1.Items(\(count\)))
\(End\ If\)
Next
\(For\ count\ = 0\ To\ ListBox1.Items.Count - 1\)
If Convert.ToInt32(ListBox1.Items(\(count\))) >= max2 And Convert.ToInt32(ListBox1.Items(\(count\))) < max1 Then
max2 = Convert.ToInt32(ListBox1.Items(\(count\)))
\(End\ If\)
Next
MsgBox("Highest Scores: " + max1.ToString() + " " + max2.ToString())
MsgBox("\(Total\): " + ListBox1.Items.Count.ToString())
\(End\ If\)
ListBox1.Items.Clear()

a. In cell C15, create a formula without using a function that subtracts the vendor cost (cell C7) and the shipping cost (cell C9) from the sales price (cell C8), and then multiplies the result by the projected number of units for sale in 2021 (cell C10). Use absolute references to each cell in the formula.
Answer:
To create a formula in cell C15 that subtracts the vendor cost (cell C7) and the shipping cost (cell C9) from the sales price (cell C8), and then multiplies the result by the projected number of units for sale in 2021 (cell C10), you can use the following formula:
=($C$8-$C$7-$C$9)*$C$10
This formula subtracts the vendor cost and the shipping cost from the sales price and then multiplies the result by the projected number of units for sale in 2021. The dollar signs before the cell references ensure that the formula uses absolute references to each cell, so the cell references don't change when you copy the formula to other cells.

Define a function below, count_over_100, which takes a list of numbers as an argument. Complete the function to count how many of the numbers in the list are greater than 100. The recommended approach for this: (1) create a variable to hold the current count and initialize it to zero, (2) use a for loop to process each element of the list, adding one to your current count if it fits the criteria, (3) return the count at the end.
Answer:
In Python:
def count_over_100(mylist):
kount = 0
for i in range(len(mylist)):
if mylist[i] > 100:
kount+=1
return kount
Explanation:
This defines the function
def count_over_100(mylist):
(1) This initializes kount to 0
kount = 0
(2) This iterates through the loop
for i in range(len(mylist)):
If current list element is greater tha 100, kount is incremented by 1
if mylist[i] > 100:
kount+=1
This returns kount
return kount

A Quicksort (or Partition Exchange Sort) divides the data into 2 partitions separated by a pivot. The first partition contains all the items which are smaller than the pivot. The remaining items are in the other partition. You will write four versions of Quicksort:
• Select the first item of the partition as the pivot. Treat partitions of size one and two as stopping cases.
• Same pivot selection. For a partition of size 100 or less, use an insertion sort to finish.
• Same pivot selection. For a partition of size 50 or less, use an insertion sort to finish.
• Select the median-of-three as the pivot. Treat partitions of size one and two as stopping cases.
As time permits consider examining additional, alternate methods of selecting the pivot for Quicksort.
Merge Sort is a useful sort to know if you are doing External Sorting. The need for this will increase as data sizes increase. The traditional Merge Sort requires double space. To eliminate this issue, you are to implement Natural Merge using a linked implementation. In your analysis be sure to compare to the effect of using a straight Merge Sort instead.
Create input files of four sizes: 50, 1000, 2000, 5000 and 10000 integers. For each size file make 3 versions. On the first use a randomly ordered data set. On the second use the integers in reverse order. On the third use the
integers in normal ascending order. (You may use a random number generator to create the randomly ordered file, but it is important to limit the duplicates to <1%. Alternatively, you may write a shuffle function to randomize one of your ordered files.) This means you have an input set of 15 files plus whatever you deem necessary and reasonable. Files are available in the Blackboard shell, if you want to copy them. Your data should be formatted so that each number is on a separate line with no leading blanks. There should be no blank lines in the file. Even though you are limiting the occurrence of duplicates, your sorts must be able to handle duplicate data.
Each sort must be run against all the input files. With five sorts and 15 input sets, you will have 75 required runs.
The size 50 files are for the purpose of showing the sorting is correct. Your code needs to print out the comparisons and exchanges (see below) and the sorted values. You must submit the input and output files for all orders of size 50, for all sorts. There should be 15 output files here.
The larger sizes of input are used to demonstrate the asymptotic cost. To demonstrate the asymptotic cost you will need to count comparisons and exchanges for each sort. For these files at the end of each run you need to print the number of comparisons and the number of exchanges but not the sorted data. It is to your advantage to add larger files or additional random files to the input - perhaps with 15-20% duplicates. You may find it interesting to time the runs, but this should be in addition to counting comparisons and exchanges.
Turn in an analysis comparing the two sorts and their performance. Be sure to comment on the relative numbers of exchanges and comparison in the various runs, the effect of the order of the data, the effect of different size files, the effect of different partition sizes and pivot selection methods for Quicksort, and the effect of using a Natural Merge Sort. Which factor has the most effect on the efficiency? Be sure to consider both time and space efficiency. Be sure to justify your data structures. Your analysis must include a table of the comparisons and exchanges observed and a graph of the asymptotic costs that you observed compared to the theoretical cost. Be sure to justify your choice of iteration versus recursion. Consider how your code would have differed if you had made the other choice.
The necessary conditions and procedures needed to accomplish this assignment is given below. Quicksort is an algorithm used to sort data in a fast and efficient manner.
What is the Quicksort?Some rules to follow in the above work are:
A)Choose the initial element of the partition as the pivot.
b) Utilize the same method to select the pivot, but switch to insertion sort as the concluding step for partitions that contain 100 or fewer elements.
Lastly, Utilize the same method of pivot selection, but choose insertion sort for partitions that are of a size equal to or lesser than 50 in order to accomplish the task.

A Meera array is defined to be an array containing only numbers as its elements and for all n values in the array, the value n*2 is not in the array. So [3, 5, -2] is a Meera array because 3*2, 5*2 or 2*2 are not in the array. But [8, 3, 4] is not a Meera array because 2*4=8 and both 4 and 8 are elements found in the array. Write a function that takes an array of numbered elements and prints “I am a Meera array” in the console if its array does NOT contain n and also n*2 as value. Otherwise, the function prints “I am NOT a Meera array” ○ Test 1: checkMeera([10, 4, 0, 5]) outputs “I am NOT a Meera array” because 5 * 2 is 10 ○ Test 2: checkMeera([7, 4, 9]) outputs “I am a Meera array” ○ Test 1: checkMeera([1, -6, 4, -3]) outputs “I am NOT a Meera array” because -3 *2 is -6
The program based on the question requirements:
The Programfunction checkMeera(arr) {
for (let num of arr) {
if (arr.includes(num*2)) {
console.log("I am NOT a Meera array");
return;
}
}
console.log("I am a Meera array");
}
The function takes an array as input and iterates through each element using a for-of loop.
For each element, it checks if its double is also present in the array using the includes() method.
If found, the function prints "I am NOT a Meera array" and returns. If no such element is found, the function prints "I am a Meera array".

Fill in the blank to complete the “increments” function. This function should use a list comprehension to create a list of numbers incremented by 2 (n+2). The function receives two variables and should return a list of incremented consecutive numbers between “start” and “end” inclusively (meaning the range should include both the “start” and “end” values). Complete the list comprehension in this function so that input like “squares(2, 3)” will produce the output “[4, 5]”.
The increment function will be written thus:
ef increments(start, end):
return [num + 2 for num in range(start, end + 1)]
print(increments(2, 3)) # Should print [4, 5]
print(increments(1, 5)) # Should print [3, 4, 5, 6, 7]

in order to overcome the gate delay problem of the simple ripple-carry adder circuit, we can design an adder with the following design improvement:
The correct answer is option d: Use a multiplexer to distribute the carry bits to subsequent columns.
The ripple-carry adder has a problem of delay due to the propagation of carry bits through each stage. By using a multiplexer to distribute carry bits, we can reduce this delay. The carry-in bit for each stage is calculated using the carry-out bit of the previous stage and the input carry bit. The carry-in bit is then passed through the multiplexer to the next stage, which reduces the delay caused by the carry propagation. This approach allows for efficient and fast addition of multi-bit numbers, making it ideal for use in applications that require high-speed arithmetic operations.
