(BASH) Say I have an array of strings with about 100 numbers ranging in length from 3-6 that represent some sort of ID. Within the array of strings, there are some duplicates numbers. What I am trying to do is represent only the top 12 numbers in the form (ID, count occurence) where its ranked by the count occurrences. So the first number would not be the ID with the most digits but it would be the one with the most occurrences.  Is there a way to do this with AWK , begin? or how could i approach this problem?

Draw the NFA for language L2 = { w | w ends in 12}. Alphabet {0,1,2}

1. What is a database? Why do today’s Internet Web applications and smartphone apps need databases?
2. For the tables given as: MEMBER (MemberNumber, MemberFirstName, MemberLastName, EmailAddress)

And PAYMENT (PaymentNumber, MemberNumber, PaymentDate, PaymentAmount)

what are the primary keys of each table? Do you think that any of these primary keys could be surrogate keys? Are any of these keys composite keys? Explain how the two tables are related. Which table contains the foreign key, and what it is the foreign key?

3. Define the terms data and information.   Explain how the two terms differ.

1. MySQL can enforce referential integrity for a delete operation performed on a parent table record by ____________________ .

A. returning an error instead of deleting any rows.

B. setting the foreign key values in the related child table rows to null.

C. deleting the related rows in the corresponding child table(s).

D. applying any one of the above, (a, b or c), depending on how the foreign key constraint is defined.

2. Third normal form (3NF) eliminates which of the following issues in a table?

A. Transitive dependencies

B. Functional dependencies

C. Partial dependencies

D. Repeating, or multi-valued columns

3. For a table to be in the second normal form (2NF), each non-primary key column in the table must __________________

A. depend on only one column that is part of the composite primary key of the given table.

B. depend on all columns that make up the composite primary key of the given table.

C. have a unique value.

This has to be in java and will be uploaded onto zybooks.

Write a Java program that asks the user for a date entered as 4 integers: dayNumber monthNumber date year. Where:

dayNumber

An integer from 1-7, where 1 = Sunday, 2 = Monday, ..., 7 = Saturday

monthNumber

An integer from 1-12, where 1 = January, 2 = February, ..., 12 = December

date

An integer from 1-31 representing the date.

year

An integer representing the year.

Your prompt to the user should be:

    Enter 4 integers representing dayNumber monthNumber date year:
  

You program will compute the proper dayName from the specified dayNumber and the proper monthName from the specified monthNumber. Your program will print out the specified date in the following format:

    dayNumber monthNumber date year is dayName monthName date, year
  

Please note your program will have to error check the input as follows:

Please note your program will have to error check the input as follows:

1. First the dayNumber is checked for being in the range 1..7. If that is not the case, your program should print out the following message and terminate execution:

       Invalid day number: dayNumber, please enter a number from 1..7.
         

2. Then the monthNumber is checked for being in the range 1..12. If that is not the case, your program should print out the following message and terminate execution:

       Invalid month number: monthNumber, please enter a number from 1..12.
         

3. Then the date is checked for being in the range 1..31. If that is not the case, your program should print out the following message and terminate execution:

       Invalid date number: date, please enter a number from 1..31.
         

4. Then the date must be checked for validity. For example, there is no February 30, February 31, April 31, June 31, September 31, November 31. If the date is invalid, your program should print out the following message and terminate execution:

       Invalid date: monthName, does not have date days, please enter a valid date.
         

5. Lastly, if the monthNumber = 2, and date = 29 you must verify that the year entered is a leap year, which is the only time that February 29 exists. Please see Wikipidia's Page on Leap Year. If the year is not a leap year and the user entered a date = 29, your program should print out the following message and terminate execution:

       Invalid date: year is not a leap year, February does not have date days, please enter a valid date.
         

Please note that your class should be named DateConverter.

This is a multiple answer question. Meaning any number of the four could be true. This is from an O/S class

We discussed in class the ability to create new processes in a Linux environment by way of the fork() function. What is true about this function?

• Identify what is the goal of `Requirement Engineering`.
• What are some common requirement elicitation activities; which activity do you think is more appropriate to use for your class project and why.
• Discuss and contrast `User Requirements` vs `System Requirement` and `Functional requirement` vs `Non-functional requirement`; Which type of requirements more important for the success of a software project.
• Discuss the two main method for capturing and modeling user requirement.
• What is the purpose of the `User Goal Technique`; what is the purpose of `Event Decomposition Technique`.
• Which technique would you use for your group project to identify and model user requirements , and why?

One of the basic motivations behind the Minimum Spanning Tree Problem is the goal of designing a spanning network for a set of nodes with minimum total cost. Here we explore another type of objective: designing a spanning network for which the most expensive edge is as cheap as possible.

Specifically, let G = (V, E) be a connected graph with n vertices, m edges, and positive edges costs that are all distinct. Let T = (V, E0 ) be a spanning tree of G; we define the bottleneck edge of T to be the edge of T with the greatest cost.

A spanning tree T of G is a minimum-bottleneck spanning tree if there is no spanning tree T 0 of G with a cheaper bottleneck edge.

(a) Is every minimum-bottleneck tree of G a minimum spanning tree of G? Prove or give a counterexample.

(b) Is every minimum spanning tree of G a minimum-bottleneck tree of G? Prove or give a counterexample.

This is a multiple answer question, meaning any of the 4 statements could be true. From O/S class

A graph G = (V, E) is a near-tree if it is connected and has at most n+ 8 edges, where n = |V |. Give an algorithm with running time O(n) that takes a near-tree G with costs on its edges, and returns a minimum spanning tree of G. Assume all the edge costs are distinct.

Given the information below, create the fully labeled Crow's Foot ERD using a specialization hierarchy where appropriate (use Visio). The ERD must contain all primary keys, foreign keys, and main attributes. Business rules are defined as follows:

At a hospital, each patient is classified as either a resident patient or an outpatient. All patients have common attributes - ID, first and last name, and diagnosis - and unique attributes that are specific to their groups. The list of such attributes includes but is not limited to the following: a summary of the treatment received in the hospital (resident patients) and the checkback date (outpatients). In addition, resident patients are classified as patients who need a routine check up, patients who need a surgery, patients who need both a check up and a surgery. Each group is characterized by unique attributes (for instance, a surgery date, etc.). Each patient creates a record in the HOURS table that keeps track of the total number of hours a patient spent in the hospital. The table also includes the “COMMENT” field where any additional information may be recorded. One record is related to one patient only.

Design a program that uses an array to store 10 randomly generated integer numbers in the range from 1 to 50. The program should first generate random numbers and save these numbers into the array. It will then provide the following menu options to the user: 1. Display 10 random numbers stored in the array 2. Compute and display the largest number in the array 3. Compute and display the average value of all numbers 4. Exit The options 2 and 3 should call an appropriate user-defined function and pass the array to the function to compute the largest and the average value respectively. Design and call these two user-defined functions. The average value should be calculated and displayed with a precision of two decimal places. The program should loop back to the main menu until the user selects the option to exit the program. Use the register storage class for two the most frequently used variables in your program. Submit your program's source code (i.e., .c file) and a file with screen captures
