Write a method named rotateright that accepts an array of integers as a parameter and rotates the values in the array to the rig

ht (i.e., forward in position) by one. each element moves right by one, except the last element, which moves to the front. for example, if a variable named list refers to an array containing the values {3, 8, 19, 7}, the call of rotateright(list) should modify it to store {7, 3, 8, 19}. a subsequent call of rotateright(list) would leave the array as follows: {19, 7, 3, 8} */

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];           
    }       
}

Answer:

Follows are the code to this question:

def FindPair(Values,SUM):#defining a method FindPair  

   found=False;#defining a boolean variable found

   for i in Values:#defining loop for check Value  

       for j in Values:#defining loop for check Value

           if (i+j ==SUM):#defining if block that check i+j=sum

               found=True;#assign value True in boolean variable

               x=i;#defining a variable x that holds i value

               y=j;#defining a variable x that holds j value

               break;#use break keyword

       if(found==True):#defining if block that checks found equal to True

           print("(",x,",",y,")");#print value

       else:#defining else block

           print("Sorry there is no such pair of values.");#print message

Values=[3,8,13,2,17,18,10];#defining a list and assign Values

SUM=20;#defining SUM variable

FindPair(Values,SUM);#calling a method FindPair

Output:

please find the attachment:

Explanation:

In the above python code a method, "FindPair" is defined, which accepts a "list and SUM" variable in its parameter, inside the method "found" a boolean variable is defined, that holds a value "false".

  • Inside the method, two for loop is defined, that holds list element value, and in if block, it checks its added value is equal to the SUM. If the condition is true, it changes the boolean variable value and defines the "x,y" variable, that holds its value.
  • In the next if the block, it checks the boolean variable value, if the condition is true, it will print the "x,y" value, otherwise, it will print a message.

If there is any kind of disturbance in the path of transmission then it causes the loss in the data packet.Therefore, the correct option is latency.

Answer:

Peg

Explanation:

This is known as the "peg technique." The name comes from the fact that we usually employ pegs to hang clothes to dry. In this memory aid, the person who wants to memorize something creates mental associations between two concrete objects. This is done in a one-to-one fashion that links all the words together.
