  1. List the players that have either won more than 2 matches or lost more than 2 matches. List the player number, name, initials, won, and lost. Insert your snip here.
  1. Which players are captains of a team and have ever served as a committee members? Display the player number, player name, initials, team number, and committee member position. This will require 3 tables. Insert your snip here.
  1. Using a subquery, have any other players been penalized the same amount as player 8? Let MySQL do the work for you. Do not explicitly query for $25. Display the player number, player name, initials, and amount. Insert your snip here.
  1. Who has played more than 2 matches? Display the player number as ‘Number’, concatenate the player name (initials, space, name) as ‘Name’, and the number of matches played as ‘Number of Matches’. Insert your snip here.
  1. Sum the number of match wins and losses by player number. Display the player number as ‘Number’, concatenate the player name (initials, space, name) as ‘Name’, wins as ‘Total Wins’, and losses and ‘Total Losses’. Insert your snip here.

JAVA

Write a test program that prompts the user to enter a list and displays whether the list is sorted or not. Here is a sample run. Note that the program first prompts the user to enter the size of the list. Using Array

My output should look like this

Enter the size of the list: 8

Enter the contents of the list: 10 1 5 16 61 9 11 1

The list has 8 integers 10 1 5 16 61 9 11 1

The list is not sorted

In Python,

Complete the longestWord() function to take a list as a parameter and return the length of the longest word in that list.

Examples:

longestWord(['Python', 'rocks']) returns 5

longestWord(['Casey', 'Riley', 'Jessie', 'Jackie', 'Jaime', 'Kerry', 'Jody']) returns 6

longestWord(['I', 'a', 'am', 'an', 'as', 'at', 'ax', 'the']) returns 3

Using Python provide the implementation of a function called "isAdjacent" that accepts a string.   The function checks if two adjacent characters in the string are the same; if they are the same, then return True otherwise return False.   The function should ignore case and check for non-empty string.  If it's an empty string, then return the message 'Empty string'.

Sample runs:

print( isAdjacent('ApPle')) # True
print( isAdjacent('Python')) # False
print( isAdjacent('')) # Empty string

SOLVE IN C: 6.31 LAB: Print string in reverse

Write a program that takes in a line of text as input, and outputs that line of text in reverse. You may assume that each line of text will not exceed 50 characters.The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text.

Ex: If the input is:

Hello there
Hey
quit

then the output is:

ereht olleH
yeH

Hint: Use the fgets function to read a string with spaces from the user input. Recall that if a newline character is read from the user input before the specified number of characters are read, the newline character itself is also written into the string.

C++ Assignment.

Design the Weather class that contains the following members:

Data members to store:

- a day (an integer)

- a month (an integer)

- a year (an integer)

- a temperature (a float)

- a static data member that stores the total of all temperatures (a float)

Member functions:

- a constructor function that obtains a day, month, year and temperature from the user. This function should also accumulate/calculate the total of all temperatures (i.e., add the newly entered temperature to the total).

- a static function that computes and displays the day which has the lowest temperature. Note: An array of Weather objects and the size of the array will be passed to this function.

- a static function that computes and displays the average temperature. This function should use a parameter, if necessary.

Design the main( ) function, which instantiates/creates any number of objects of the Weather class as requested by the user (i.e., creates a dynamic array of Weather objects). main( ) should also call appropriate functions to compute and display the day that has the lowest temperature, as well as the average temperature. Your program should include all necessary error checking.

A sample run of this program could be as follows:

How many days => 4

Enter day, month, year, temperature => 29 11 2018 15.6

Enter day, month, year, temperature => 30 11 2018 8.7

Enter day, month, year, temperature => 1 12 2018 3.1

Enter day, month, year, temperature => 2 12 2018 3.5

Lowest temperature = 3.1 C, Day 1/12/2018

Average temperature = 7.7 C

Q:You have to write a function that contains three varibles as the following

Diamond

Write the deleteNode() member function, which is also given in our textbook implementation. This function takes a const T& as its parameter, which is the value of an item to search for and delete. Thus the first part of this function is similar to the search() function, in that you first have to perform a search to second the item. But once found, the node containing the item should be removed from the list (and you should free the memory of the node). This function is only guaranteed to find the first instance of the item and delete it, if the item appears multiple times in the list, the ones after the first one will still be there after the first item is removed by this function. This function should return a LinkedListItemNotFoundException if the item asked for is not found. The LinkedListItemNotFoundException class has already been defined for you in the starting template header file.

Here is the cpp for main and LinkedList - https://paste.ofcode.org/37gZg5p7fiR243AD4sD5ttU

Consider the following relation with structure EMPLOYEE_DATA (EmployeeID, EmployeeDegree, DepartmentID, DepartmentName)

EmployeeID EmployeeDegree DepartmentID DepartmentName
001 Mathematics 1004 R&D
001 Mathematics 1004 R&D
002 Info. Systems 2003 Cybersecurity
003 Computer Sci 5816 Software

The functional dependencies are as follows: EmployeeID → EmployeeDegree, DepartmentID → DepartmentName, (EmployeeID,DepartmentID) → (EmployeeDegree, DepartmentName).

Put the above relation into BCNF. For your solution use the shorthand TABLENAME (primarykey1, primarykey2, attribute1, attribute2).

Last Statement. Look,- I'm a retired electrician of 30 years that's been through some life, and then some..? I saw Linus Sabastian on "Linus Tech Tips" and he made building PCs fun. He made them fun, and easy to learn how to assemble, transfer files, and some other things as well. I thought, because of the way he teaches the GUI to be fun that I could go to my Local Community College and learn CLI but here is the big problem with that?

CLI hasn't had anybody that can come up with a way to make it easy to learn, and fun, and until somebody does I'm going back to the GUI, and where the fun is.....To learn CLI I need the answer 1st to all my assignments just like learning how to build PC's on YouTube, and then I could at least begin to see how the answers are used in the questions of the assignment asked? I'm backward, and I learn visually just like Youtube teaches with having the answers in our hands. 1st.

To all the College Professors in the world that teach Linux and Windows Command Line, When one of you decides to give the answers with your assignments so the students don't have to spend valuable hours research hunting and you wonder why there failing the class? Do something different & radical for a change give the whole class the answers to all the assignments and then Linux will be fun, and we will understand the assignment because we can now see the answers to it. Sincerely T
