Design a finite state machine that accepts binary strings divisible by 5. Input is fed to the FSM one bit at a time, from the most significant bit to the least significant bit (left to right). For example, 1010 should be accepted, but 1100 should be rejected. Clearly explain how you designed your state transitions. Showing the FSM alone is worth minimal credit!

Implement function (in C programming) that calculates and returns the total size of items in a directory given by name.

• Only consider immediate contents (no need to recursively check subdirectories).
• Assume that appropriate header files are included (no need to specify them using #include).

int dir_size(const char *name);

2. Basic arithmetic calculation.
   1. Use instruction “li” to initialize register $t1 with a constant value 10.

li $t1, 10   # [$t1] <- 10

finish the following calculation using MIPS assembly code.

$t2 = $t1 + $t1

$t3 = $t1 << 2 (shift to left by 2 bits)

$t4 = $t1 & 0x0000ffff (bitwise AND)

$t5 = $t1 | 0x0000fffff (bitwise OR)

$t6 = $t2 + $t3 + $t4 + $t5

Write MIPS assembly code to finish the above calculation and print out the result, value of $t6.

BankAccount:
You will create 3 files: The .h (specification file), .cpp (implementation file) and main file. You will practice writing class constants, using data files. You will add methods public and private to your BankAccount class, as well as helper methods in your main class. You will create an array of objects and practice passing objects to and return objects from functions. String functions practice has also been included.

1. Extend the BankAccount class. The member fields of the class are: Account Name, Account Id, Account Number and Account Balance. The field Account Id (is like a private social security number of type int) Convert the variables MIN_BALANCE=9.99, REWARDS_AMOUNT=1000.00, REWARDS_RATE=0.04 to static class constants Here is the UML for the class:

2. Create a file called BankAccount.cpp which implements the BankAccount class as given in the UML diagram above. The class will have member variables( attributes/data) and instance methods(behaviours/functions that initialize, access and process data)
3. Create a driver class to do the following:
   1. Read data from the given file BankData.data and create and array of BankAccount Objects

The order in the file is first name, last name, id, account number, balance. Note that account name consists of both first and last name

2. Print the array (without secret id) similar to Homeowork2 EXCEPT the account balance must show only 2 decimal digits. You will need to do some string processing.
3. Find the account with largest balance and print it
4. Find the account with the smallest balance and print it.
5. Determine if there are duplicate accounts in the array. If there are then set the duplicate account name to XXXX XXXX and rest of the fields to 0. Note it’s hard to “delete” elements from an array. Or add new accounts if there is no room in the array. If duplicate(s) are found, print the array.

MATLAB

Write a code that takes the initial velocity and angle as an input and outputs the maximum height of the projectile and its air time.

Follow the pseudo code below. This will not be provided in as much detail in the future so you’ll have to provide pseudocode or a flowchart to showcase your logic. For this first assignment though, the logic is laid out below with some indented more detailed instructions.

PROGRAM Trajectory:
Establish the User Interface (Typically referred to as the UI);

INPUT INPUT

Solve
Solve
Print

Start with an explanation of activity

Ask the user for the initial velocity;

Ask the user for the initial angle;

Include descriptive requests for inputs so the user knows what information is required.

for the maximum height the ball reaches;

for the length of time the ball is in the air;

the answers for the user;

Include a description with that return so the user understands what the data is

Plot height versus time; Plot height versus distance;

Do not overwrite your previous figure! This is a new plot but you still want the old one.

Make it clear what the plots are. Label the plot axes with units, include a title, and use a marker for the plot points.

Can someone show me how to make this javaFx code work?

The submit button should remain disabled until:
● There is text in all three fields.
● The two password fields have the same value.
When Submit is clicked, display an Alert that says “Account
Created!”
When Quit is clicked, display an Alert that asks the user if
they are sure they want to quit. If they click OK, quit the
program with System.exit(0). If they click Cancel, the
program keeps running.

Find the largest number of divisions made by Euclid’s algorithm for computing gcd(m, n) for 1≤ n ≤ m ≤ 100.

Function named FunCount takes three arguments-

C, an integer representing the count of elements in input list

IP- input list of positive integers.

Item- an integer value.

Function FunCount returns an integer representing the count of all the elements of List that are equal to
the given integer value Key.

Example: Don’t take these values in program, take all inputs from user

C = 9, IP= [1,1,4,2,2,3,4,1,2], Item = 2
function will return 3

Add a CountGroups method to the linked list class below (OurList). It returns the number of groups of a value from the list. The value is passed into the method. A group is one or more values.

Examples using strings:
A list contains the following strings: one, one, dog, dog, one, one, one, dog, dog, dog, dog, one, one, dog, one
   CountGroup(“one”) prints 4 groups of one's
   CountGroup(“dog”) prints 3 groups of dog's

Python 3.7:

1. Write a generator expression that repeats each character in a given string 4 times. i.e. given “gone”, every time you call the next method on the generator expression it will display “gggg”, then “oooo”, … etc and instantiate it to an object called G.  G = (…..) # generatorExpression object

2. Test and verify that iter(G) and G are the same things. What does this tell you about the nature of a Generator object/expression?

3. Assign Iter(G) to an iterator object called it1 and advance it to the next element by using next method.

4. Instantiate a new Iter(G) object called it2. Use the next method and advance it to the next element. Observe the result and compare it with the results of it1.

5. Does the new Iter(G) object start the iterator from the start of the string object? Write down your understanding/conclusion from this experiment.

6. How can you get back the Iter(G) to point back to the beginning of the string?
