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.

The expression "2 << 6" is equivalent to multiplying 2 by 2^6, which is 64. So, "2 << 6" results in 64. The bitwise NOT operator () flips all the bits of the expression that follows it, and the bitwise AND operator (&) performs a logical AND between the original value of A and the result of the NOT operation.

Explanation:

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. These records are stored and communicated to other data user when required or needed.

A relational database can be defined as a type of database that is structured in a manner that there exists a relationship between its elements.

Hence, when a user completes a form online by providing his or her name, address, and credit card information in order to make a purchase, he or she is giving the company structured data (pre-defined and formatted to a set structure) that can be used to make up (populate) a relational database or spreadsheet.

Answer:

A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.

First, let's convert -9/2 to a decimal number: -9/2 = -4.5

Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:

1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM

Sign bit: Since the number is negative, the sign bit is 1: 1

Mantissa and exponent: Convert -4.5 into binary and normalize it:

-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2

Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)

Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101

Now, put the sign, exponent, and mantissa together: 1101 0010

So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.

B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.

To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:

Sign bit: 1

Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)

Mantissa: Smallest mantissa is 0000

The 8-bit representation is 1001 0000. Converting this to decimal:

-1 * 2^{-2} * 1.0000 which is -0.25.

The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.

C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.

To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:

Sign bit: 0

Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)

Mantissa: Largest mantissa is 1111

The 8-bit representation is 0110 1111. Converting this to decimal:

1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.

The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.

```

import java.util.Arrays;

public class ArraySumRowWise {

   public static void main(String[] args) {

       int m = 3;

       int n = 4;

       int[][] arr = {{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}};

       // Print the original array

       System.out.println("Original Array:");

       for (int[] row : arr) {

           System.out.println(Arrays.toString(row));

       }

       // Compute and print the row wise sum

       System.out.println("Row Wise Sum:");

       for (int i = 0; i < m; i++) {

           int rowSum = 0;

           for (int j = 0; j < n; j++) {

               rowSum += arr[i][j];

           }

           System.out.println("Row " + (i+1) + ": " + rowSum);

       }

   }

}

```

Explanation:

In this program, we have created an array of size 3 X 4 and initialized it with some values. We have then printed the original array and computed the row wise sum by iterating over each row and adding up all the elements. Finally, we have printed the row wise sums. You can replace the values of m, n, and arr with your own values to test the program with different array sizes and values.

In Python:

def MPH(miles,minutes):

   mph = round(60 * miles/minutes,1)

   return mph

miles = float(input("Miles: "))

minutes = float(input("Minutes: "))

if miles>0 and minutes>0:

   print("MPH: ",MPH(miles,minutes))

else:

   print("Positive inputs only")

Explanation:

This defines the function

def MPH(miles,minutes):

This calculates mph rounded to 1 decimal place

   mph = round(60 * miles/minutes,1)

This returns the calculated mph

   return mph

The main begins here

This gets input for miles    

miles = float(input("Miles: "))

This gets input for minutes

minutes = float(input("Minutes: "))

If miles and minutes are positive

if miles>0 and minutes>0:

This calls the MPH function

   print("MPH: ",MPH(miles,minutes))

If otherwise, this prompts the user for positive inputs

else:

   print("Positive inputs only")

Answer:

Linked lists and arrays are both linear data structures but while an array is a collection of items that can be accessed randomly, a linked list can be accessed sequentially.

A sparse matrix contains very few non-zero elements. For example;

_                        _

|  0   0   3  0  6    |

|   0   5   0  0  4   |

|   2   0   0  0  0   |

|_ 0   0   0  0  0 _|

In the implementation of a sparse matrix, the following are some of the pros and cons of using a linked list over an array;

PROS

i.  Linked lists are dynamic in nature and are readily flexible - they can expand and contract without having to allocate and/or de-allocated memory compared to an array where an initial size might need to be set and controlled almost manually. This makes it easy to store and remove elements from the sparse matrix.

ii. No memory wastage. Since the size of a linked list can grow or shrink at run time, there's no memory wastage as it adjusts depending on the number of items it wants to store. This is in contrast with arrays where you might have unallocated slots. Also, because the zeros of the sparse matrix need not be stored when using linked lists, memory is greatly conserved.

CONS

i. One of the biggest cons of linked lists is the difficulty in traversing items. With arrays, this is just of an order of 0(1) since the only requirement is the index of the item. With linked lists, traversal is sequential which means slow access time.

ii. Storage is another bottle neck when using linked lists in sparse matrix implementation. Each node item in a linked list contains other information that needs to be stored alongside the value such as the pointer to the next or previous item.
