Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture.  Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…

Python Answer Required: A Rajesh teaches a cooking class. The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Input 1 1 hasan jaddouh Output hasan

CSCI 2436:01L Data Structures Lab Lab 1 - Chapter 4 The Efficiency of Algorithms In this lab, you will practice how to measure the running time f a section of code in Java. One approach is to use System.nano Time() where the current time is stored as a long integer equals to the number of nanoseconds. By subtracting the starting time in nanoseconds from the ending time in nanoseconds, you get the run time-in nanoseconds of a section of code. public static void main(String[] args) { int n1 = 10, n2 = 100, n3 = 1000, n4 = 10000; long n1Time, n2Time, n3Time, n4Time; n1Time AlgorithmA (nl); For example, suppose that AlgorithmA is the name of a method you wish to time. The following statements will compute the number of nanoseconds that AlgorithmA requires to execute: } public static long AlgorithmA (int n) { long startTime, endTime, elapsedTime; startTime = System.nanoTime (); int sum = 0; for (int i = 1; i 0 1 2.

Write VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column.  (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades.  You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA.  For this problem you can assume that all classes are worth the same number of credit hours.  The function should send back the GPA to the calling procedure.  The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box.  The message should be “You qualify for an internship” if the student has a GPA of at least 3.0.  It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0.  And it should be “You are on…

Part III - Create Your Own Art  Art.java In this part you will create a program Art.java that produces a recursive drawing of your own design. This part is meant to be fun, but here are some guidelines in case you're not so artistic. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. For full credit, Art.java must not be something that could be easily rewritten to use loops in place of recursion, and some aspects of the recursive…

Data Structures the hasBalancedParentheses () method. Note: this can be done both iteratively or recursively, but I believe most people will find the iterative version much easier. C++: We consider the empty string to have balanced parentheses, as there is no imbalance. Your program should accept as input a single string containing only the characters ) and (, and output a single line stating true or false. The functionality for reading and printing answers is written in the file parentheses.checker.cpp; your task is to complete the has balanced.parentheses () function. **Hint: There's a pattern for how to determine if parentheses are balanced. Try to see if you can find that pattern first before coding this method up.

Write a program in Java, Python and Lisp When the program first launches, there is a menu which allows the user to select one of the following five options: 1.) Add a guest 2.) Add a room 3.) Add a booking 4.) View bookings 5.) Quit The functionality of these options is as follows: 1.) When users add a guest they provide a name which is stored in some manner of array or list. Guests are assigned a unique ID value where the first guest added is assigned the ID value 1, the second guest added is assigned the ID value 2 and so on. 2.) When users add a room they provide a room number and a room capacity (i.e. how many people can stay in the room at any one time) which is stored in some manner of array or list. Rooms have a property which indicates if they are booked or not for any given date – please see the Room Booking Dates section below for some guidance on the easiest way to implement this. 3.) When users add a booking they provide a guest ID, room number, the number…

Topical Information Use C++. This lab is designed to give you practice with labeled data in files. Again, classes can help ease your design woes. Program Information Write a program that transfers the contents of one file to a second file. The first file will contain an arbitrary (unknown) number of data groups. A data group will normally consist of a person's name (a string containing spaces), the person's student ID (a large integer), the person's GPA (a floating point number), and the person's gender (a character). The data in each group should be in a labeled data format. Be sure to use some kind of string library to help you with the label/value processing (as we discussed in class). (The library provided here is good but not everything you'll need. You still need functions to convert strings into integers and into floating point numbers. string to bool, string to string, and string to character conversions should be fairly easy.) You can choose the actual values to use for the…

Programming: C#(C sharp) without using (array, while and furthermore advance loop) Someone i know posted this here already but he got the wrong answer. I was hoping i can get the right one.

In C In this problem, you will recreate one of the truly great moments in history, namely the classic race of the tortoise and the hare. You will use random number generation to develop a simulation of this memorable event and use pointers to store / track the position of the two race contestants.   Our contenders begin the race at “square 1” of 70 squares. Each square represents a possible position along the race course. The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce. The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground.   There is a clock that ticks once per second. With each tick of the clock, your program should adjust the position of the animals according to the rules shown in the table below.   Implement the “race course” as an integer array containing the numbers from 1 to 70. Implement the positions of the tortoise and the hare as pointers,…
