Part 1: Write a Python function called reduceWhitespace that is given a string line and returns the line with all extra whitespace characters between the words removed.

For example, ‘This line has extra space characters'

'This line has extra space characters’

• Function name: reduceWhitespace

• Number of parameters: one string line

• Return value: one string line The main file should handle the file operations to read from a .txt file you create and call the function from the module you create.

In main you should also print out your text from the file before the function call and print the result after the function call, showing that the function works. Additionally, write the lines with reduce whitespaces into a text file.

Your function should also include the specification (docstring).

Note: the code will be tested by giving it a .txt file, so you should prompt the user for the text file.

Lab 9 Part 2:

In the same module, write a Python function named countAllLetters that is given a string line and returns a list containing every letter and character in the line and the number of times that each letter/character appears (with upper/lower case letters counted together).

For example,

‘This is a short line’ -> [(‘t’,2), (‘h’,2), (‘i’,3), (‘s’,3), (‘ ‘,4), (‘a’,1),

(‘o’,1), (‘r’,1), (‘l’,1), (‘n’,1), (‘e’,1)]

• Function name: countAllLetters

• Number of parameters: one string line

• Return value: a list

The main file should handle the file operations to read from a new .txt file you create and call the function from the module you create. In main, you should print out the text you read from the file, then call the function and then print out the resulting list, showing that the function works. You do not need to write the output into a text file.

Your function should also include the specification (docstring).

Note: the code will be tested by giving it a .txt file, so you should prompt the user for the text file.

Suppose that we want to make change for n cents using the least number of coins. The coins are of denominations c 0 , c 1 , . . . , c k for some integers c > 1, and k ≥ 1. (a) Design a greedy algorithm to solve this problem. (b) Prove that your algorithm finds an optimal solution by showing the greedy-choice property and optimal substructure for it. Clearly state each property and then prove them.

I am working java project. I need to write methods for text game. I'm working on chest class.

Description : You should start your work by implementing the Chest class (a skeleton is provided for you). It needs to store whether it is locked or not, a String describing the contents, and which key it was locked with. The method stubs for this class are provided with comments, be sure to implement them the way they are described. You should not add any more methods to this class.

public class Chest {

   /*
   * Instance variables go here, you're responsible for choosing
   * which ones are needed and naming them
   */

   /**
   * This method is used by the Map class, you won't need to call it yourself
   * It should result in this chest being locked and storing which key locked it.
   */
   public void lock(Key theKey) {
      
       Key rightKey = theKey;
      
   }
  
   /**
   * If theKey is the same key that was used to lock this chest, then
   * the chest is unlocked. Otherwise this method does nothing.
   */
   public void unLock(Key theKey) {
   }
  
   /**
   * Should return true if the chest is locked, false otherwise
   */
   public boolean isLocked() {
   }
  
   /**
   * Return a string describing the contents of the chest.
   */
   public String getContents() {
   }
  
   /**
   * Set the contents of the chest to this string. You should not need to call
   * this method in your program (though you have to implement it anyway).
   */
   public void setContents(String contents) {
   }
  
  
  
}

Programming assignment (100 pts): In the C++ programming language write a program capable of playing Tic-Tac-Toe against the user. Your program should use OOP concepts in its design. You can use ASCII art to generate and display the 3x3 playing board. The program should randomly decide who goes first computer or user. Your program should know and inform the user if an illegal move was made (cell already occupied). The program should also announce if one of the players wins or if a draw is achieved. While it is desirable for your program to play a strong game, this is not an Artificial Intelligence course so if your program does not play at a world champion level you will not be penalized for it.

I've been looking at other post for this question and nothing is working.

Please write a half page summary on the following topic: How does product liability affect IT?

why are which letters, such as A, B, C, ..., or signs, such as #, *, •, ..., are not allowed to be sent on a URL to a Web server.

//Java Language

Read an integer number from the user. If the number is not positive, change its sign.

  
1   Count the digits of the number
2   Count the odd digits of the number
3   Calculate the sum of the digit values of the number

Design a class named BankAccount to hold the following data for a bank account:

Balance
Number of deposits this month
Number of withdrawals
Annual interest rate
Monthly service charges
The class should have the following methods:

Constructor:

The constructor should accept arguments for the balance and annual interest rate.

deposit:

A method that accepts an argument for the amount of the deposit. The method should add the argument to the account balance. It should also increment the variable holding the number of deposits.

withdraw:

A method that accepts an argument for the amount of the withdrawal. The method should subtract the argument from the balance. It should also increment the variable holding the number of withdrawals.

calcInterest:

A method that updates the balance by calculating the monthly interest earned by the account, and adding this interest to the balance. This is performed by the following formulas:

Monthly Interest Rate 5 (Annual Interest Rate / 12)

Monthly Interest 5 Balance * Monthly Interest Rate

Balance 5 Balance 1 Monthly Interest

monthlyProcess:

A method that subtracts the monthly service charges from the balance, calls the calcInterest method and then sets the variables that hold the number of withdrawals, number of deposits, and monthly service charges to zero.

Next, design a SavingsAccount class that extends the BankAccount class. The SavingsAccount class should have a status field to represent an active or inactive account. If the balance of a savings account falls below $25, it becomes inactive. (The status field could be a boolean variable.) No more withdrawals may be made until the balance is raised above $25, at which time the account becomes active again. The savings account class should have the following methods:

withdraw:

A method that determines whether the account is inactive before a withdrawal is made. (No withdrawal will be allowed if the account is not active.) A withdrawal is then made by calling the superclass version of the method.

deposit:

A method that determines whether the account is inactive before a deposit is made. If the account is inactive and the deposit brings the balance above $25, the account becomes active again. A deposit is then made by calling the superclass version of the method.

monthlyProcess:

Before the superclass method is called, this method checks the number of withdrawals. If the number of withdrawals for the month is more than 4, a service charge of $1 for each withdrawal above 4 is added to the superclass field that holds the monthly service charges. (Don’t forget to check the account balance after the service charge is taken. If the balance falls below $25, the account becomes inactive.)

Input
100
0.03

2.5

Where,

First line represents the balance.

Second line represents the interest rate.

Third line represents the monthly service charge.

Output

Balance: $100.00
Number of deposits: 0
Number of withdrawals: 0
Account Status: Active

Balance: $170.00
Number of deposits: 3
Number of withdrawals: 0
Account Status: Active

Balance: $20.00
Number of deposits: 3
Number of withdrawals: 2
Account Status: Incative

Balance: $17.54
Number of deposits: 0
Number of withdrawals: 0
Account Status: Incative

# Use the provided template for the demo class to fill the missing code to input data and output result as shown above. Do not change the withdraw and deposit code!

Code needed in Java
The purpose of the application is to generate some reports about the people of the university. So a user of the application should be able to view information about the people in the university and generate summaries. As in implementation these are separated into two major categories, employee and students, we will be implementing these classes.  

The system should have three classes: Person, Employee and Student.Employees and students are subclasses of persons and therefore, they inherit some fields and methods from the superclass Person. What Employee class has as an extra is a field called job which is a String value that indicates the position of the employee at the university. The possible values are ‘Faculty’ and ‘Staff’ and the rest of the input should be rejected. Another significant field is UIN (you may assume it to be an integer).Students also have a similar structure. A field called level, gives information regarding the student. Possible values are ‘Undergraduate’ and ‘Graduate’ and the rest of the input should be rejected. Also A number should be implemented (you may assume A number to be a string).  
Once you create these classes write your test class with main method.  

The output of such an application would look like:  

Person’s first name is Triss, last name is Merigold. She is 25 years old.
Person’s first name is Sigismund, last name is Dijkstra. He is 37 years old. His UIN is 793942 and serves the university as a staff.
Person’s first name is Keira, last name is Metz. She is 19 years old. Her A-number is A021318 and she is an undergraduate student

Using Python Programming

PROBLEM 3 - OLD MACDONALD: Write a program to print the lyrics of the song ”Old MacDonald”. Your program should print the lyrics using five different animals (i.e., cow, sheep, dog, cat ,turkey) using the example verse below. For this problem you are required to write then make use of a function getVerse that takes two string parameters: (1) the name of an animal and (2) the sound that animal makes. The function should not print anything if the name of the animal is not one of the five above, or if there is a mismatch between the animal and the sound. In your program, call your function 5 times, passing each time to the function a different combination of animal name and sound. The five different animals and their associated sounds are the followings:
Animal Sound

cow moo

sheep baaa

dog woof

cat meow

turkey gobble gobble

About Cache, computer organization, computer architecture, computer science.

Cache Question:

A[0] is at memory address 0x0FED CBA0. Array B[] is right after array A[] in the data memory.

Both arrays have 10 integers

Based on memory address for A[0] of 32 bits, i know that the cache index and tag is 27 bits, offset is 4 bits and index is 1 bit.

Q: Will the tag and cache index change for A[8] and B[8]? And how will it change?

I personally feel that tag and cache index will not change for A[8]. But i'm not too sure about B[8]

Q: Does the cache behaviour affect the A[8] and B[8]?

E.g. Direct mapped cache vs 2-way set-associative cache

IN JAVA, For this exercise, you will create your own example of using a generic method. First write a program that calls a method to multiply two integers and return the integer result. Then modify that program to make the method generic, calling it with two generic data types (T1 and T2) and then returning the result in the same type (also needs to be generic). Demonstrate your program by calling the method two times, once with an integer and once with a double. In your main program, display the results of the method call showing both an integer output and a decimal output. Submit code for both your original method (non-generic) and your revised method (generic), along with execution screenshots.
