Dates: 2 9 16 23 30

Example Execution #2:

Enter day of week (1-7) -> 2

Enter month of the year -> 10

Enter the year -> 2019

Finding: There are not five Monday dates in October of 2019.

Using JavaScript for the following assignment

Design and code a function named "intersection" that

takes two arrays of numbers in parameter and returns a new

array containing only the values that are both in the

two arrays. A value must not be found more than once in

the resulting array but can be found more than once in

the arrays in parameter. The order of the elements in the resulting array

must respect the order of the first parameter. For example :

      intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3])

must return [3, 4].

You also need to design and code a unit test function and

call it. To test that the result of

      intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3])

which returns [3, 4], you can use a test like this:

      assert (intersection ([3, 1, 4, 1, 5], [2, 4, 4, 3]) == "3,4");

This works because the == operator does the automatic conversion

from arrays to text (if one of the two operands are a text).

Add two Cisco 2960 switches and wire it up accordingly; use a crossover cable.

After you have added the switches, add the following devices and wire accordingly.

Configure the following information on the computers:

Configure the following items:

• Set passwords for the Console and VTY 0 4 lines.
• The password should be set for login and the password should be "P@ssword#1".
• Set a enable password that is a secret; the password should be "P@ssword#2".
• Set a banner that is appropriate.

• Enable the service for securing passwords.

In Python: read in 'marks.txt' . The file format is one number per line. Your program will run through all these numbers, and make sure that they are valid input.

you have to Create two lists: one for valid numbers and one for invalid numbers.

For a number to be valid the number has to:

Must be less than or equal to 100

Must be greater than or equal to 0

Must not have any letters inside of it (it must be numeric -- use the string function .isnumeric())

Print out list of bad inputs, and print out average of the good inputs.

Please discuss and explain the concept of Corporate Information Security. What is it? Why is it important?

What type of misses are reduced by each of these cache optimization techniques. List all types of misses reduced for full credit. In addition, list the possible disadvantages of using the optimization technique.

•Data and instruction prefetching:

•Pipelined cache accesses:

•Higher associativity :

•Larger cache capacity:

Choose one of the following cryptography techniques and implement it using (java )programming language. Your program should provide the user with two options Encryption and Decryption, with a simple UI to get the input from the user, and view the result. You can use any restriction you need for the user input but you need to clarify that and validate the user input base on your restriction.

You are going to write a program that takes two inputs: A string representing a list of names of the following form: first name 1, last name 1, (nick name 1); first name 2, last name 2, (nick name 2); ... A string representing part of or the complete family name. You are going to output all nick names for those names where there is a partial or complete match of the family name. If no match was found you should output: Not found! Here a few examples.

Names: Chun Kit, Chui (Kit gor); Dirk, Schnieders (Dirk); Jun-fan, Lee (Bruce); Rowan Sebastian, Atkinson (Bean)

Family name: Schni

Imagine you are a student enrolled in a College course where the course grade is calculated using a weighted average. (It might not be too hard to imagine.) It’s nearing the midterm of the semester and you want to know what your grade is. Luckily, your professor has provided you with a syllabus, and in that syllabus he or she has listed the formula for calculating your course grade. (This is sounding more familiar all the time.)

Graded Activity Percentage

Exams are 30%

Projects are 30%

Assignments are 15%

Quizzes are 5%

You will notice that the weighted percentages only add up to 80% of the total grade. That’s because the final exam will represent the last 20% of your grade. That said, let’s calculate our current grade with only the grades we have SO FAR, and ignoring the final exam part. You want to write a program that asks you for all of your grades, one graded activity at a time, one grade at a time. (See the SAMPLE RUNS section below.)

You need to write a program that does this making use of the following functions:

void printPrompt(int a)

– This function accepts a single incoming integer (value 1 through 4). Depending on the value of the incoming integer the function prints out the prompt to enter grades of a certain type (quiz grades, assignment grades, exam grades, and project grades) and tells the user to enter -1 to quit. This function is only responsible for printing the prompt and accepts NO user input. It also returns nothing.

double average()

– This function takes no incoming data (no parameters), but it does receive input from the user through cin. The user enters a series of integer grades with a -1 to terminate input. It also calculates the average of all inputs entered. This average is returned as a double.

double weightedAverage(double, double, double, double)

– This function takes in four double values which represent the averages of the four types of graded activity. It calculates and returns the current weighted average, in the form of a double.

void outputAverages(double, double, double, double, double)

– This function accepts five double values: the four graded activity averages calculated before, as well as the overall weighted average. The function prints out the average of each type of grade; quiz average, assignment average, exam average, and project average, as well as the current grade in the course. It has no outgoing data (no return values).

PROVIDED SKELETON CODE:

For this assignment we have provided part of your solution for you. Specifically, we have provided a file where we have listed all the necessary function declarations as well as a main function that makes calls to these functions. DO NOT MODIFY either the function declarations OR the main function.

Your job will be to add the function definitions below the main function. A completed and

fully functional program should result if you correctly define these functions.

SAMPLE RUNS:

Sample Run 1:

Enter your quiz grades (-1 to end input):

100 95 90 85 -1

Enter your assignment grades (-1 to end input):

50 100 100 25 0 -1

Enter your exam grades (-1 to end input):

65 -1

Enter your project grades (-1 to end input):

80 93 75 -1

Your quiz average: 92.5

Your assignment average: 55

Your exam average: 65

Your project average: 82.6667

Your current grade in this course is: 71.4687
