a. Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions.

b. The expected number of inversions, E[X],  E[X] = 1/4n(n-1).

c. In the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

(a) Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions. To understand why this is true, let's refer to the pseudocode for Insertion-Sort:

InsertionSort(A):

  for i from 1 to length[A] do

     key = A[i]

     j = i - 1

     while j >= 0 and A[j] > key do

        A[j + 1] = A[j]

        j = j - 1

     A[j + 1] = key

b. The expected number of inversions, E[X], can be calculated as follows:

E[X] = Σ(i,j) E[I(i, j)]

= Σ(i,j) Pr((i, j) is an inversion)

= Σ(i,j) 1/2

= (n(n-1)/2) * 1/2

= n(n-1)/4

Hence, E[X] = 1/4n(n-1).

(c) Using Proposition 2 and the result from part (b), we can determine the average case time complexity of Insertion-Sort. The average case time complexity is given by O(n + E[X]).

Substituting the value of E[X] from part (b):

Average case time complexity = O(n + 1/4n(n-1))

Simplifying further:

Average case time complexity = O(n + 1/4n^2 - 1/4n)

Since 1/4n² dominates the other term, we can approximate the average case time complexity as:

Average case time complexity ≈ O(1/4n²)

Therefore, in the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

The total number of AC cycles completed in one second is referred to as the current's frequency. Therefore, the correct answer is frequency. (option c)

Define AC current: Explain that AC (alternating current) is a type of electrical current in which the direction of the electric charge periodically changes, oscillating back and forth.

Understand cycles: Describe that a cycle represents one complete oscillation of the AC waveform, starting from zero, reaching a positive peak, returning to zero, and then reaching a negative peak.

Introduce frequency: Define frequency as the measurement of how often a cycle is completed in a given time period, specifically, the number of cycles completed in one second.

Unit of measurement: Explain that the unit of measurement for frequency is hertz (Hz), named after Heinrich Hertz, a German physicist. One hertz represents one cycle per second.

Relate frequency to AC current: Clarify that the total number of AC cycles completed in one second is directly related to the frequency of the AC current.

Importance of frequency: Discuss the significance of frequency in electrical engineering and power systems. Mention that it affects the behavior of electrical devices, the design of power transmission systems, and the synchronization of different AC sources.

Frequency measurement: Explain that specialized instruments like frequency meters or digital multimeters with frequency measurement capabilities are used to accurately measure the frequency of an AC current.

Emphasize the correct answer: Reiterate that the current's frequency represents the total number of AC cycles completed in one second and is the appropriate choice from the given options.

By understanding the relationship between AC cycles and frequency, we can recognize that the total number of AC cycles completed in one second is referred to as the current's frequency. This knowledge is crucial for various aspects of electrical engineering and power systems. Therefore, the correct answer is frequency. (option c)

Here's an example program in C++ that fulfills the requirements:

_______________________________________________________

#include <iostream>

#include <fstream>

#include <vector>

using namespace std;

int main() {

   const int ARRAY_SIZE = 1000; // Set a large size for the array

   double array[ARRAY_SIZE];

   double sum = 0.0;

   int count = 0;

   // Read the first five elements from the keyboard

   cout << "Enter the first five elements of the array:\n";

   for (int i = 0; i < 5; i++) {

       cout << "Element " << i + 1 << ": ";

       cin >> array[i];

       sum += array[i];

       count++;

   }

   // Read the remaining elements from a file

   ifstream inputFile("input.txt"); // Replace "input.txt" with your file name

   double num;

   while (inputFile >> num && count < ARRAY_SIZE) {

       array[count] = num;

       sum += array[count];

       count++;

   }

   inputFile.close();

   // Calculate and print the average

   double average = sum / count;

   cout << "Average of array elements: " << average << endl;

   return 0;

}

________________________________________________________

In this C++ program, a large array of doubles is declared with a size of 1000. The first five elements are read from the keyboard using a for loop, and the sum and count variables keep track of the cumulative sum and the number of elements entered.

The remaining elements are read from a file named "input.txt" (you should replace it with the actual file name) using an ifstream object. The program continues reading elements from the file as long as there are more numbers and the count is less than the array size.

Finally, the average is calculated by dividing the sum by the count, and it is printed to the console. Remember to replace "input.txt" with the correct file name and double-check the average with a calculator to ensure accuracy.
