When you want to copy a formula while keeping one of the cell references locked on the same cell, you would use Absolute Reference. Absolute Reference is a technique in Excel that is used to maintain the reference of a cell even after copying the formula.
In other words, the Absolute reference is used to keep a cell reference constant even if the formula is copied to a new location. It can be created by placing dollar signs before the column and row designations in a cell reference. For example, if a formula refers to cell A1 and we want to keep the reference of this cell constant even after copying the formula to a new cell, then we can use the absolute reference.
This can be done by changing the reference from A1 to $A$1.So, option (b) Absolute Reference is the answer.

What technology allows user to boot five different operating systems from one computer with one hard drive? Volume Bootble GUID Partition Table Apple Partition Map Master Boot Record
The technology that enables users to boot five different operating systems from one computer with one hard drive is known as multi-booting. It is achieved through the use of partitioning schemes like GUID Partition Table (GPT), Apple Partition Map, and Master Boot Record (MBR) to create separate sections on the hard drive for each operating system.
Multi-booting is the practice of installing and running multiple operating systems on a single computer. This allows users to choose which operating system they want to use when starting up their computer. To accomplish this, different partitioning schemes can be employed.
GUID Partition Table (GPT) is a partitioning scheme that is widely used on modern computers. It supports up to 128 partitions and can accommodate various operating systems. Each operating system is installed on a separate partition, allowing the computer to boot into the desired system.
Apple Partition Map is a partitioning scheme primarily used on Apple Macintosh computers. It allows for multiple operating systems to be installed on separate partitions, similar to GPT.
Master Boot Record (MBR) is an older partitioning scheme that is still used on some computers. It supports up to four primary partitions, but additional logical partitions can be created within an extended partition. By allocating each operating system to a separate partition, multi-booting is achieved.
By utilizing these partitioning schemes and allocating different partitions for each operating system, users can boot into any of the five operating systems installed on their computer from a single hard drive.

dekker’s mutual exclusion algorithm does not use a test-and-set instruction. True or False.
Dekker's mutual exclusion algorithm does not use a test-and-set instruction. This statement is True.
Dekker's Algorithm is a mutual exclusion algorithm that solves the problem without the use of locks. A critical section is a section of code that only one process can execute at a time in a multi-process or multi-threaded environment. Dekker's algorithm is the first-known algorithm that solves the mutual exclusion issue without using locks. In Dekker's algorithm, a flag is used to keep track of each process's desire to execute the critical section. The process that sets its flag first is allowed to execute the critical section first. While it is executing the critical section, the other process must wait for the flag to change. It operates in the following way:
Initialize both flags (flag0 and flag1) to zero. Assign the process P0 (process0) to flag0 and the process P1 (process1) to flag1.Process0 sets its flag to 1 and then checks whether Process1 has set its flag or not. If it has set its flag, then it will wait.Process0 will then enter into the critical section. If Process0 has completed the critical section, it will reset flag0 to 0. Otherwise, Process1 will have to wait.Process1 sets its flag to 1 and then checks whether Process0 has set its flag or not. If it has set its flag, then it will wait. Process1 will then enter into the critical section. After completing the critical section, it will reset flag1 to 0.

write the augmented matrix for each system of equations. 649-02-03-00-00_files/
I apologize, but I cannot view or access any external files or images. However, I can help you understand how to create an augmented matrix for a system of equations.
An augmented matrix represents a system of linear equations in matrix form, where the coefficients of the variables and the constants are organized in a rectangular matrix.
For example, consider the system of equations:
2x + 3y = 5
4x - 2y = 8
To create the augmented matrix, we organize the coefficients and constants as follows:
[ 2 3 | 5 ]
[ 4 -2 | 8 ]
In this matrix, the left side represents the coefficients of the variables (2x, 3y, 4x, -2y), and the right side represents the constants (5, 8). The vertical bar separates the coefficient matrix from the constant matrix.Note that the number of rows in the augmented matrix corresponds to the number of equations, and the number of columns corresponds to the number of variables plus one (for the constants).You can create augmented matrices for other systems of equations following a similar approach.

the truth value of an array with more than one element is ambiguous.
An array is a collection of elements that are of the same data type, and each of them has a unique identifier. In computing, it is used to organize data and for easy access. The truth value of an array with more than one element is ambiguous because a single condition cannot fully determine the truth or falsity of the entire array.
Consider an array with two or more elements. If we were to test the condition of the array to determine its truth value, we would have to test each element in the array. This is because a single element can be true or false, but the entire array cannot be true or false as a single entity. To overcome this problem, we can use a loop to iterate through each element in the array and test the condition.
If the condition is true for all elements in the array, then the entire array is considered true. However, if the condition is false for at least one element, then the entire array is considered false. In conclusion, the truth value of an array with more than one element is ambiguous, and we must test each element to determine its truth or falsity.

In the given code, there is an error message indicating a "warning: assignment makes pointer from integer without a cast." This error occurs at the line ptr = strtok(str, " ");. The warning suggests that there is an implicit conversion from an integer to a pointer without a proper cast.
To resolve this issue, you need to ensure that the variable ptr is declared as a pointer to a character (char *), as required by the strtok function. You can correct this by declaring ptr as char *ptr; before using it.
Additionally, there are a few other issues in the code. The variable type is declared as an array of characters (char type[5];), but you are trying to assign a string to it using type = ptr;. To copy the string, you should use the strcpy function instead, like strcpy(type, ptr);.
Furthermore, the variables n and remain are declared as integers, but you are trying to assign a string to them using n = ptr; and remain = n;. To convert the string to an integer, you can use the strtol function, like n = (int)strtol(ptr, (char **)NULL, 10); and remain = n;.
Lastly, in the printf() statement inside the if condition, there is a missing argument.
To summarize, the code has a warning due to an incorrect assignment of a pointer without a cast. To fix this, declare ptr as char *ptr; before using it. Additionally, use strcpy to assign a string to type, and convert the strings to integers using strtol for n and remain. Make sure to provide the necessary argument in the printf() statement.

The C function given in the question is an implementation of a function named howManyBits that takes an integer x as input and returns the minimum number of bits required to represent x in two's complement. The implementation takes advantage of bit-wise operations and relies on bit shifting and Logical operations to compute the number of bits required to represent the input value in two's complement.
The function first initializes a variable n to 0 and then sets x to be equal to the bit-wise exclusive OR of x and x right shifted by 31 bits. This is done to make sure that all the bits in x are positive, which is required to represent the value in two's complement notation.Next, the implementation uses a series of logical operations to compute the number of bits required to represent the input value. Specifically, it shifts x by n + 16, n + 8, n + 4, n + 2, and n + 1 bits and then uses the double exclamation mark operator to check if the result is non-zero. If the result is non-zero, the implementation adds the corresponding value to n.
Finally, the implementation shifts x by n bits, adds 1 to n, and then returns n.The implementation uses a total of 12 operations to compute the number of bits required to represent the input value. The maximum number of operations allowed is 90. Therefore, the implementation is quite efficient and works well for a variety of inputs, including positive and negative integers as well as zero.

There is a sorting algorithm, "Stooge-Sort" which is named after the comedy team, "The Three Stooges." if the input size, n, is 1or 2, then the algorithm sorts the input immediately. Otherwise, it recursively sorts the first 2n/3 elements, then the last 2n/3 elements, and then the first 2n/3 elements again. The details are shown in Algorithm below.
Algorithm StoogeSort(A, i, j ):
Input: An array, A, and two indices, i and j, such that 1 <= i <= j < n
Output: Subarray, A[i..j] ,sorted in nondecreasing order
n <- j – i + 1 // The size of the subarray we are sorting
if n = 2 then
if A[i] > A[j] then Swap A[i] and A[j]
else if n > 2 then
m <- (floor function) n/3(floor function)
StoogeSort(A, i, j-m) // Sort the 1st part.
StoogeSort(A, i+m, j) // Sort the last part.
StoogeSort(A, i, j-m) // Sort the 1st part again.
return A
1. Show that Stooge-sort is correct by Mathematical Induction
2. Characterize the running time, T(n) for Stooge-sort using as recurrence equation.
3. By means of Master's Method, determind an asymptotic bound for T(n)
4. Solve the recurrence equation in 2. by meas of 'Ierative Substitution' method.
1. Show that Stooge-sort is correct by Mathematical InductionThe Stooge Sort algorithm can be shown to work correctly using mathematical induction. For n=2, the algorithm sorts the input immediately by comparing the first and last element in the input list.
Let's assume that the algorithm sorts correctly for an input size of 2 to n-1. When n>2, the algorithm recursively sorts the first 2n/3 elements, then the last 2n/3 elements, and then the first 2n/3 elements again. This can be done in three steps:1) Recursively sort the first 2n/3 elements.2) Recursively sort the last 2n/3 elements.3) Recursively sort the first 2n/3 elements again.
2. Solve the recurrence equation in 2. by means of the Iterative Substitution method.To solve the recurrence relation T(n) = 3T(2n/3) + O(1) using the Iterative Substitution method, we can assume that T(n) is of the form T(n) = O(nlogb(a)).Substituting T(n) = cnlogn(2/3) into the recurrence relation yields:T(n) = 3T(2n/3) + O(1)T(n) = 3c(nlog(2/3)) + O(1)T(n) = cnlog(2/3) + O(1)Multiplying both sides by log(3/2) yields:log(3/2)T(n) = clogn(2/3)log(3/2)3Substituting k=log(3/2) yields:T(n) = knlogn(2/3)Multiplying both sides by log(3/2) yields:log(3/2)T(n) = klogn(2/3)log(3/2)Substituting k=log(3/2) yields:T(n) = nlogn(3/2)Therefore, the time complexity of Stooge Sort algorithm is O(nlogn(3/2)), which is equivalent to O(n^2.7095).

The final sorted array is 2, 3, 14, 32, 43, 73, 80. The time complexity of the heap sort algorithm is O(n log n), which is the same as that of the merge sort algorithm.
Heap Sort AlgorithmHeap sort is a sorting technique based on the Binary Heap data structure. Heapsort algorithm is used for sorting an array in ascending or descending order. It is a comparison-based sorting algorithm that finds the maximum or minimum value and puts it at the end of the array. Heap sort is not a stable sort. A stable sort algorithm preserves the relative order of identical elements.The array after each iteration is:After the 1st iteration: 80 43 73 14 32 3 2After the 2nd iteration: 73 43 2 14 32 3 80After the 3rd iteration: 43 32 2 14 3 73 80After the 4th iteration: 14 3 2 32 43 73 80After the 5th iteration: 3 2 14 32 43 73 80The final sorted array is 2 3 14 32 43 73 80.The total number of iterations is log n, where n is the number of elements in the heap. The time complexity of the heap sort algorithm is O(n log n), which is the same as that of the merge sort algorithm.
Therefore, the array after each loop iteration is: After i = 4: 80, 43, 73, 14, 32, 3, 2After i = 3: 80, 43, 73, 14, 32, 3, 2After i = 2: 80, 43, 2, 14, 32, 3, 73After i = 1: 80, 3, 2, 14, 32, 43, 73The final sorted array is 2, 3, 14, 32, 43, 73, 80. Therefore, the 100 word answer to the given question is:The array after each iteration is 80, 43, 73, 14, 32, 3, 2 for i=4; 80, 43, 73, 14, 32, 3, 2 for i=3; 80, 43, 2, 14, 32, 3, 73 for i=2; and 80, 3, 2, 14, 32, 43, 73 for i=1.
