In the RMON hostTopN table (20.14.1.4 Host Top N), the agent does all the report-building work. Would it be possible for the manager to do this? If not, why not? If so, why do you think RMON provides this table?

4. Rewrite the following pseudocode segment using a loop structure in the specified languages:

k = (j + 13) / 27
loop:
      if k > 10 then goto out
      k = k + 1
      i = 3 * k - 1
      goto loop
out: . . .

a. C++

b. Python

c. Ruby

Assume all variables are integer type. Discuss the relative merits of the use of these languages for this particular code.

2. Let the function fun be defined as

int fun(int*k) {
      *k += 4;
      return 3 * (*k) - 1;
}

Suppose fun is used in a program as follows:

void main() {
      int i = 10, j = 10, sum1, sum2;
      sum1 = (i / 2) + fun(&i);
      sum2 = fun(&j) + (j / 2);
}

What are the values of sum1 and sum2

a. operands in the expressions are evaluated left to right?

b. operands in the expressions are evaluated right to left?

This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program).

Type in Python please.

. Consider QuickSort on the array A[1:n] and assume that the pivot element x (used to split the array A[lo:hi] into two portions such that all elements in the left portion A[lo:m] are ≤x and all elements in the right portion A[m:hi] are ≥x) is the second element of the array to be split (i. e., A[lo+1]).

For a specific value of n at least 13 (your choice), construct an assignment of the numbers 1...n to the n array elements that causes QuickSort, with the stated choice of pivot, to

(a) execute optimally (that is A[lo:m] and A[m:hi] are always of equal size)

(b) execute in the slowest possible way.

1. Maryland Animal Sanctuary and Rescue is a small Pet adoption place right here in our area and has different animals up for adoption. Design an application for their pets, creating a class diagram and writing the pseudocode for both the class definition and the application. Be sure to follow the Style Criteria for naming conventions, class diagrams, pseudocode, keywords, and operators.
   1. Create the UML class diagram for the Pet class that contains the type of the pet, the breed of the pet, and the weight. Examples of valid values for the type of the pet are "dog" and "rabbit". Examples of valid values for the breed are "husky" and "checkered giant". Examples of valid values for the weight are 32 and 3 1/2. Be sure to choose the most appropriate data type for the attributes. Include the methods of the Pet class listed below as well as the application class. Add the correct relationship and multiplicity.
   2. Create a class definition
      • Create a Pet class that contains the attributes in the class diagram. Additionally, include the following:
        • A default constructor that initializes each attribute to some reasonable default value for the pets.
        • Another constructor method that has a parameter for each data member. This constructor initializes each attribute to the value provided when an object of this type is instantiated.
        • Accessor and mutator methods for each attribute.
        • A method that displays all the data about the pets.
   3. Create the main application
      • Write the pseudocode for the application program for the pet sanctuary with a main() module that instantiates two objects of the Pet class.
        • The first object should be named dog and use the default constructor.
        • The second object should be named cat and use the second constructor to initialize the type to "cat", the breed to "Siamese", and the weight to 3.  
      • Include the following instructions in the main() method, in the order specified below
        • A call to set the type of the dog to "Large Dog".
        • A call to set the breed of the dog to “German Shephard”.
        • A call to set the weight of the dog to 50.
        • A Statement that displays the breed of the cat, using the appropriate method call.
        • A call to change the weight of the dog to 45.
        • A statement that displays the weight of the dog, using the appropriate method call.
        • A call for the cat object to the method that displays all the information about the cat.
        • A call for the dog object to the method that displays all of the information about the dog.

1. Write a program to ask user to enter an integer that represents the number of elements, then generate an ArrayList containing elements which are all random integers in range [75, 144] , and finally display index and value of each element.

REQUIREMENTS

• The user input is always correct (input verification is not required).
• Your code must use ArrayList.
• Your program must use only printf(…) statements to adjust the alignment of your output.
• Your code must display the index in descending order.
• Your output must be displayed with the same alignment as the example (the text in bold indicates the user input).

Example of the program output:

Example 1:

Enter the number of elements: 5

Index   Element

4       129   

3       138   

2       134   

1       98    

0       84

Example 2:

Enter the number of elements: 12

Index   Element

Message passing is both time- and space-coupled – that is, messages are both directed towards a particular entity and require the receiver to be present at the time of the message send. Consider the case of using the learning platform, where you connect using URL “learning rather than an IP address and this name is resolved using DNS. Does such a system exhibit the same level of indirection?
