I have already wrote the code, I only need someone to provide a prompt to let users enter their input.

(my code is in attached file)

Programming 2– RPN Calculator –

Infix to Postfix Conversion and The Evaluations of the Postfix Expression.

You are to design and implement and algorithm in Java, to input an Infix expression , convert to a postfix expression and finally evaluate the postfix expression Problem description:

1.We are used to infix notation – ”3 + 4” – where the operator is between the operands. There is also prefix notation, where the operand comes before the operands. A Reverse Polish Notation calculator uses postfix notation, and was one of the first handheld calculators built. At first, it seems confusing, but is very logical once you think about it. Instead of doing ”2 + 3 + 4”, you may do ”2 [enter] 3 [enter] 4 [enter] + +”.

2.You will be implementing a conversion from infix to RPN and then perform an RPN calculator for this assignment.

3.How does an RPN calculator work? It is quite simple in principle. The calculator keeps a stack – a list of numbers. When you type a number and hit ”enter”, it pushes, or appends the number to the stack. So you build up a stack of numbers. Whenever you click an operand, it applies the operator to the top of the stack. In the previous example, it builds a stack like [2, 3, 4]. When you hit the first ”+”, it pops off the top/most recent two elements off the list and ”pluses” them. Lastly, it pushes the result back on the stack, so it looks like [2, 7]. When you hit plus again, it pops off the two elements (so the stack is temporarily empty), adds them, and pushes it back on the stack, so you get [9] .

3 What you need to do

For the first part of this assignment, think about what classes you need. Java has a Stack class for you, but write your own (do not use the Java Stack class). Use encapsulation, think about what methods it should have, and call it something like CalculatorStack. Add an option to” roll” the stack; shift it left or right by one (and the end number rollls) to the other end). Other classes may include Controller, Handler, or SpecialOperationsHandler.

4 Why?

• It’s one of the better assignments I can think of as a teaching tool

• RPN calculators are awesome – they’re far more logical than infix calculators once you get used to them

• You should learn RPN calculators; besides the historical importance, it forces you to think differently. Several example done during class lectures.

The following code below is a sample on how to evaluate the RPN expression …

1: watch the video Shrek musical that i will post it. choose two part of dance and describe as well. then watch the same performance on youtube and choose two part of dance and describe as well. ( describe what you see, its about theatre technology in theatre dance, and what is different between of two of them)

2: watch the two video about Cinderella dance.and choose two part of dance and describe what you can see the all of the technology in theatre dance)

Be sure this senior thesis paper is about Analysis in use of Technology in Theatre dance , you don’t need write introduction and conclusion. Only follow my two section will be great. I need 10 page with double space thanks

will have to create a crime scene sketch hand drawn no computer assistance and take a clear picture of it. also fill out the evidence report i have attached to this.

Background:

You are a law enforcement first responder who has been dispatched to a call of a residential burglary at 231 Main Street, Dirty City. In addition to writing an evidence log, you need to create a hand-written sketch of the scene and collect evidence. The assigned case number for this sketch and log is 13-00123.

Assignment:

Using your own residence or the residence of a family member or friend, create a hand-drawn (no computer assistance) sketch in the overhead view of 231 Main Street.

Be sure to properly document interior/exterior windows and doors and any additional key elements to the sketch (sheds, outbuildings, etc…as needed)

Properly label your sketch

1. Label the sketch for proper geographic reference/orientation
2. Location information
3. Case number
4. Date of sketch
5. Is the sketch “To scale” – Be cautious here. Make sure you understand what you are indicating if you draw this sketch ‘To Scale’

Label evidence items in the sketch

You must include the following items:

1. Fingerprint on an exterior window
2. Used cigarette in bathroom
3. Hammer in kitchen
4. Screwdriver in a bedroom
5. Window screen left on the ground below a window
6. Night watch cap on ground
7. Half-filled can of beer on the kitchen counter
8. Photographs you took at the scene (you do not need to take photographs. Just note that you took them and they are being logged as evidence)

Create an evidence list/log

Properly document evidence collection

1. Property tag # (create a property tag # or use D12345)
2. Item # (each piece of evidence will have it’s own number)
3. Item description
4. Date and time the item was located
5. Who located the evidence item
6. Where was the item located
7. Who collected the item
8. Who logged the item
9. Where was the item logged in at
10. Any request for lab work – Explain why you need it

Additional guidelines:

1. This assignment will be graded using the Assignment # 2 rubric.
2. Your paper will be free of plagiarism. The sketch must be hand drawn (no computer assistance). The evidence log must typed.
3. Your paper will be grammatically sound and free of spelling and punctuation errors.
4. The assignment will be submitted via Canvas. Make sure your name is no where on your assignment, instead create an alias.

Within the Discussion Board area, write 400–600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.

Refer to the Lower Colorado Dams Network as the network, which you will allocate your resources. You have $30 million to allocate to the Lower Colorado Dams Network. Use an allocation model, methodology, or strategy to help allocate $30 million dollars to be apportioned. Review the Unit 4 Webinar on the Lower Colorado River Risk Assessment for an example allocation model.

• Unit 4 Webinar https://class.ctuonline.edu/_layouts/MUSEViewer/As…

Be true to the allocation strategy’s concept, and answer the following questions:

• What specific monies will you assign to which assets, links, network components, or sector elements? Explain how your allocation model guided your decisions.
• What strengths does your allocation model have to allocating resources to this network? Be comprehensive and specific in your answer.
• What shortcomings or detriments does your allocation model reveal for allocating resources to this network? Be comprehensive and specific in your answer.
• Provide 2–3 modifications to this model that would enhance it for allocating resources to this network. If you believe this model is ideal and no modifications are necessary, explain why you believe this.
• APA Format, in text citation
