Java programming language should be used
Implement a class called Voter. This class includes the following:
a name field, of type String.
An id field, of type integer.
A method String setName(String) that stores its input into the name attribute, and returns the
name that was just assigned.
A method int setID(int) that stores its input into the id attribute, and returns the id number
that was just assigned.
A method String getName() that return the name attribute.
A method int getID() that returns the id attribute.
A constructor method that takes no inputs, and then sets the name attribute to none and the
id attribute to -1.
A constructor method that takes both an integer and a string, in that order. The integer is
stored in the id attribute, and the string gets stored in the name attribute.
Implement a Voters class (notice the ‘s’ at the end of the class name).
In terms of attributes, this class will simply have a HashSet of Voter inside.
As methods, implement the following:
▪ boolean addVoter(Voter), which adds the input Voter to the set and returns true, if the voter doesn’t exist in the set already. If the voter does exist in the set, the method returns false. Two objects of type Voter are equal if they have the same ID.
▪ boolean deleteVoter(int), which deletes the Voter from the set that has the passed integer as its ID, and returns true, if the voter exist in the set. If the voter does not exist in the set, the method returns false.
▪ boolean isASubsetOf(Voters), which returns true if the Voters for which it is called is a subset of the Voters it receives as input. Otherwise, it returns false.
Instantiate two objects of class Voters
▪ an object called registeredVoters.
▪ An object called votersWhoHaveCastBallots
You should test your code with a main program. In that main program you should do the following:
▪ add different voters to the registeredVoters object.
▪ Try to add a voter to the registeredVoters that already exists. You should get an error
message.
▪ Try to delete a voter from the registeredVoters that doesn’t exists. You should get an
error message.
▪ Try to delete a voter from the registeredVoters that does exists. You should get a
message confirming that the operation was carried out.
▪ Add a voter to votersWhoHaveCastBallots who is not in registeredVoters. Check to see
if the HashSet inside votersWhoHaveCastBallots is a subset of the HashSet inside registeredVoters. This should cause your program to display an error message notifying of this fact, and display the voter object that caused the problem.
◦ Next, run the deleteVoter method on votersWho HaveCastBallots until it is a subset of registeredVoters. Check to see if votersWhoHaveCastBallots is a subset
of registeredVoters. This should cause your program to display a message notifying of this fact, and displaying the elements of votersWhoHaveCastBallots which cause this error message.

1. Write a function which receives four arguments (array, start, end, delimiter). Copy the array values from the start to end index separated by delimiter\'s value. function([1,2,3,4],1,3,'*') // returns 2*3*4 as string
2. Write a function to change the case of all the characters in string based on their position which matches the value of the pos parameter passed to function(str, pos [even|odd]). Example: function(‘abCd’, ‘odd’) // returns Abcd
3 Write a function which receives two arguments (array, oddOrEven) based on the value of oddOrEven (odd or even value) the function will return the sum of all the array elements that matches the type of oddOrEven value. function([1,1,2,3,4],11) // returns 5 (which is the sum of all odd numbers)

You will create a number of threads—for example, 100—and each thread will request a pid, sleep for a random period of time, and then release the pid. (Sleeping for a random period of time approximates the typical pid usage in which a pid is assigned to a new process, the process executes and then terminates, and the pid is released on the process's termination.) On UNIX and Linux systems, sleeping is accomplished through the sleep() function, which is passed an integer value representing the number of seconds to sleep.

Hello, I am very new to 64-bit ARM assembly and would like the code to this following question:
The Fibonacci Sequence is a series of integers. The first two numbers in the sequence are both 1; after that, each number is the sum of the preceding two numbers.
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...
For example, 1+1=2, 1+2=3, 2+3=5, 3+5=8, etc.
The nth Fibonacci number is the nth number in this sequence, so for example fibonacci(1)=1, fibonacci(2)=1, fibonacci(3)=2, fibonacci(4)=3, etc. Do not use zero-based counting; fibonacci(4)is 3, not 5.
Your assignment is to write an ARM assembler code (Fibonacci.s) that prompts the user for the nth term of the fibonacci sequence. The program will then calculate the users selected nth fibonacci term and print it out.
The program should produce this input:
Enter the desired Fibonacci term: 6
The 6th Fibonacci number is: 8
Please include comments about what the functions do in the code, thank you so much! Additionally note, I am compiling this code on a raspberry pi 3. So any additional comments would be most helpful.

Question 3:
You are requested to design an algorithm to check whether a key pair (sum of two numbers only) exist in a given array (of size N) or not. If the key pair exists at least once then the algorithm should return “True”; otherwise “False”.
For example, given an array A[8, -3, 9, 5, -3, 11, 2, -7, 4, 11] where the key pair is 13, then the required algorithm should return “True” because such pair exist at least once ex:(9+4). Another example, given the same array, where the key pair is 21, the required algorithm should return “false”, as there is no any pair with sum equal to 21
iii. What is the complexity of this algorithm in the best and worst case? (5 marks

continent a new nation, conceived in liberty and dedicated to the
proposition that all men are created equal

For my assignment, I was supposed to make a number guessing game. The class, HiLo, should pick a random number between 1 and 100 (inclusive). Then, prompt the user to guess the number. On each guess, print if the user is correct or if the guess is too high or too low. Allow only 5 guesses. In the end, print out the correct answer and how many attempts were made.
Then give the user the option to play again (1 for yes and 0 for no).
I have tried to do this but I get stuck on making it so that there are only 5 guesses and I always get an error when asking the option to play again.
