The best thing to do when an error message appears when it is not supposed to, as in if you are blocked by an administrator and it appears then its supposed to, it is best to contact someone who can investigate whether or not something is happening to your computer. That could be a parent, if they are good with computers, or just tech support at a store, provided they also know computers. Most of the time your computer just makes a mistake so nothing to worry about, but make sure to have it checked just to be sure.

Write a method named rotateright that accepts an array of integers as a parameter and rotates the values in the array to the rig
trasher [3.6K]
You should really state what language you are using. I have produced your method in C#, and should be easily translatable in to any other language.

static void RotateRight<T>(T[] arr)
{          
    T temp = arr[arr.Length - 1];
   
    for (int i = arr.Length - 1; i >= 0; i--)
    {               
        if (i == 0)                   
            arr[i] = temp;               
        else                   
            arr[i] = arr[i - 1];           
    }       
}

5.14 Describe how the compare and swap() instruction can be used to provide mutual exclusion that satisfies the bounded-waiting
Naddik [55]

Answer:

Explained below

Explanation:

Compare and Swap(C&S) is simply an atomic operation whereby the compare and swap operations are automatically executed.

Now compare and Swap basically needs 3 arguments namely:

- 2 old values which we will label X and Y

- 1 new value which is written in X that we will call Z

Thus, we now have; C & S = {X, Y, Z}

To explain this well, let X be a variable where X has a value of 7.

Now, if a programmer gives a program me that X be multiplied by 2,then what C&S operation will do is;

I) Y = X where Y is a new variable.

II) Result = C&S(X, Y, X*7)

Variable X is global and this means that mere than one process and more than 1 thread can see the variable X.

Now, if a process named P1 wants multiply the variable X by 7 using C&S operation, it will first make a local copy of variable X (which in this case is now the new variable Y). After that it will atomically compare X & Y and if they are equal, it will replace X with 10X.

However, if they are not equal, P1 will re-read value of X into Y and carry of C&S instruction again.

The second finger on the left hand types _____.<br><br> 3 E D C<br> 1 Q A Z<br> 7 U J M<br> 8 I K ,
hram777 [196]
The first finger on the left (Index) is choice "2" (1,Q,A,Z)

The second finger on the right (Middle) is choice "4" (8,I,K)

The first finger on the right (Index) is "3" (7,U,J,M

Which leaves choice "1" (3,E,D,C)

Hope this helps
