Answer:

Here's a C++ program that takes a positive integer as input, and outputs a string of 1's and 0's representing the integer in reverse binary:

#include <iostream>

#include <string>

std::string reverse_binary(int x) {

   std::string result = "";

   while (x > 0) {

       result += std::to_string(x % 2);

       x /= 2;

   }

   return result;

}

int main() {

   int x;

   std::cin >> x;

   std::cout << reverse_binary(x) << std::endl;

   return 0;

}

The reverse_binary function takes an integer x as input, and returns a string of 1's and 0's representing x in reverse binary. The function uses a while loop to repeatedly divide x by 2 and append the remainder (either 0 or 1) to the result string. Once x is zero, the function returns the result string.

In the main function, we simply read in an integer from std::cin, call reverse_binary to get the reverse binary representation as a string, and then output the string to std::cout.

For example, if the user inputs 6, the output will be "011".

Here's a Java pseudocode implementation of the selection sort algorithm with comments and loop invariants:

```java

// Selection Sort Algorithm

public void selectionSort(int[] arr) {

   int n = arr.length;

   for (int i = 0; i < n - 1; i++) {

       int minIndex = i;

       // Loop invariant: arr[minIndex] is the minimum element in arr[i..n-1]

       for (int j = i + 1; j < n; j++) {

           if (arr[j] < arr[minIndex]) {

               minIndex = j;

           }

       }

       // Swap the minimum element with the first element

       int temp = arr[minIndex];

       arr[minIndex] = arr[i];

       arr[i] = temp;

   }

}

```The selection sort algorithm repeatedly selects the minimum element from the unsorted part of the array and swaps it with the first element of the unsorted part.

The outer loop (line 6) iterates from the first element to the second-to-last element, while the inner loop (line 9) searches for the minimum element.

The loop invariant in line 10 states that `arr[minIndex]` is always the minimum element in the unsorted part of the array. After each iteration of the outer loop, the invariant is maintained.

The swap operation in lines 14-16 exchanges the minimum element with the first element of the unsorted part, effectively expanding the sorted portion of the array.

This process continues until the entire array is sorted.

Remember, this pseudocode can be directly translated into Java code, replacing the comments with the appropriate syntax.

Answer: the answer is A.

Explanation:

First let us find what this algorithm compute:

Algorithm Mystery(n) {

        S = 0;

        for i = 1 to n do

             { S = S + i * i; }

         return S }

1)

Let suppose n = 3

S = 0

The algorithm has a for loop that has a loop variable i initialized to 1

At first iteration:

i = 1

S = S + i * i;

   = 0 + 1 * 1

S = 1

At second iteration:

i = 2

S = 1

S = S + 2 * 2;

   = 1 + 2 * 2

   = 1 + 4

S = 5

At third iteration:

i = 3

S = 5

S = S + 3 * 3;

   = 5 + 3 * 3

   = 5 + 9

S = 14

Now the loop breaks at i=4 because loop iterates up to n and n =3

So from above example it is clear that the algorithm computes the sum of squares of numbers from 1 to n. Or you can say it compute the sum of first n squares.  Let us represent this statement in mathematical form:

∑\(\left \ {{n} \atop {i=1}} \right.\) i²

2)

From above example we can see that the basic operation is multiplication. At every iteration loop variable i is multiplied by itself from 1 to n or till n times. However we can also say that addition is the basic operation because at each iteration the value of S is added to the square of i. So it takes the same amount of time.

3)

In the for loop, the basic operation executes once. We can say that at each iteration of the loop, multiplication is performed once. Suppose A(n) represents the number of times basic operation executes then,

A(n) = ∑\(\left \ {{n} \atop {i=1}} \right.\) 1 = n

4)

Since for loop executes once for each of the numbers from 1 to n, so this shows that for loop executes for n times. The basic operation in best, worst or average case runs n times. Hence the running time of Θ(n) . We can say that A(n) = n ∈ Θ(n)  

If b is the number of bits needed to  represent n then

b = log₂n + 1

b = log₂n

So

n ≈ \(2^{b}\)

A(n) ≈ \(2^{b}\) ≈ Θ( \(2^{b}\) )  

5)

One solution is to calculate sum of squares without using Θ(n) algorithm.  So the efficient algorithm that takes less time than the previous algorithm is:

Algorithm Mystery(n) {

        S = 0;

        S = (n * ( n + 1 ) (2n + 1) ) / 6 ;

        return S}

Now the sum can be calculated in Θ(1)  times. This is because regardless of the size and number of operands/operations, the time of arithmetic operation stays the same. Now lets find out how this algorithm works for

n = 3

S = (n * ( n + 1 ) (2n + 1) ) / 6 ;

 = (3 * ( 3 + 1 ) * (2(3) + 1) ) / 6

 = (3 * (4) * (6+1)) / 6

= (3 * (4) * (7)) / 6

= (3 * 4 * 7) / 6

= 84 / 6

S = 14

Answer:

The final case in selection sort is trivially sorted.

The final iteration in insertion sort is not needed.

Explanation:

For selection sort, you make sub arrays and find the smallest element placing it in the front and repeat until sorted.  This guarantees the final element will already be the greatest element, thus it is trivially sorted.

For Insertion sort, you use the initial element and compare it to the previous element and swap if the current is larger than the previous.  Using this sort, you will always perform n-1 comparisons where n is the total amount of elements in the array.  Thus, there are only 11 iterations for a 12 element array.

Here's an example of a program written in the High-Level Assembly (HLA) language by Randall Hyde to achieve the desired task:

assembly:

program BigNumber;

#include( "stdlib.hhf" )

static

n: int8;

digit: int8;

count: int8;

counter: int8;

procedure PrintDigit;

begin PrintChar( AL + '0' ); end PrintDigit;

procedure PrintPattern;

begin

mov( digit, n );  // Set initial digit value

for( count := 1; count <= n; count := count + 1 ) do

begin

 for( counter := 1; counter <= count; counter := counter + 1 ) do

 begin

  call PrintDigit;

 endfor;

 mov( digit, digit - 1 );  // Decrement digit value

endfor;

end PrintPattern;

begin BigNumber;

stdout.put( "Gimme a decimal value to use for n: " );

stdin.get( n );

stdout.put( "Here's your answer: " );

call PrintPattern;

stdout.newln();

end BigNumber;

This program starts by prompting the user to input an `int8` value, `n`. It then proceeds to display the repeated digit pattern as described in the problem statement.

The `PrintDigit` procedure is used to print a single digit, obtained by adding the value in the `AL` register to the ASCII value of '0' and printing it as a character.

The `PrintPattern` procedure uses nested loops to generate the repeated digit pattern. It iterates `count` from 1 to `n`, printing the current digit `count` number of times. After each inner loop iteration, it decrements the `digit` value to generate the subsequent digit pattern.

Finally, the `BigNumber` main procedure displays the prompt, calls the `PrintPattern` procedure, and adds a new line to the output.

When executed, the program will prompt the user for a decimal value, display the repeated digit pattern based on the input, and provide the expected output.

eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.

eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.

The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.
