Exercise 19.
Repeat Exercise 3. with the contestant pulling the block of ice with a rope over his shoulder at the same angle above the horizontal as shown in Figure 5.7(b).

in java

A NavigableSet is a set that stores it’s element in order. Say we have a bunch of items
and we want to store them in order but we don’t want any duplicates. Write a generic
class that implements a structure that does that.

C data structure

Initially, we do not need to do any error checking - we can assume that the input postfix expression is syntactically correct.

Input

The input is a string that represents a postfix expression. To simplify the problem, your calculator will be restricted to operating on single-digit non-negative integers. Only the following characters are allowed in the string:

• the operators '+', '-'. '*', and '/'

• the digits '0' through '9'

• the space (blank) character ' '

Example input:

  7 8 5 * +

Processing

To handle spaces in the input, need to make one minor addition to the algorithm

  if (ch is a blank)

      ignore it

   end if

Program should ask the user to enter a text file with postfix expression on a single line. we can either read the line one character at a time, or can read the line into a string and then process the string one character at a time. Your program should then print the value of the expression. program should include a loop so that the user can evaluate multiple postfix expressions. Your output might look like:

  Enter postfix expression:

   5 8 9 + *

   The value of the expression is result of postfix

   More expressions (Y or N)? Y

   Enter postfix expression:

   9 5 /

   The value of the expression is 1

   More expressions (Y or N)? N

program should perform integer calculations only(single digit only). Do not use floating-point (float or double) variables for your calculations.

--------------------------------------------------------------------------------------------------------------------

Second part would be interesting in this part we have to do error checking after calculator thoroughly tested.

Error checking

1). Invalid character in the input expression- if the error occurs, print an error message stating that an invalid character was encountered.

2) Stack is empty when the algorithm needs to remove an operand- this happens when the expression has too many operators or when the operators and operands are not ordered correctly. We call this a malformed expression, if this occurs, print an error message indicating that the expression is malformed.

3). When the loop in the algorithm ends, there should be exactly one value left on the stack and it is the value of input expression. If the input contained too many operands, there will be more than one value left on the stack. If you remove what should be the result of the expression and the stack is not empty, then the expression was malformed and should print error message indicating.

In all cases, if an error occurs do not try to continue processing the input string and do not try to print the value of the expression. Just print the error message. Do not end application- just ask user if he wants to try another expression.

(2) On one day a man who claimed to be Dr. Bun, of NoTrue WallPaper Ltd., the expert wallpaper, persuaded Harry to buy the wallpaper for interior decoration. Harry bought 100 rolls wallpaper for HK$50,000 for Susan's apartment. He signed a written contract without bothering to read it. The contract said that NoTrue WallPaper Ltd. would have no liability for any defect in the wallpaper. When Harry used the wallpaper, they are wet and cannot put onto the wall. Harry goes back to NoTrue WallPaper Ltd., but it is already shut down. Harry immediately reported to the police and Consumer Council, but he was told that the man who had sold wallpaper to Harry was a rogue pretending to be Dr. Bun. Advice Harry of his legal position.

(3) Harry completes the first stage of the contracted design work. In reliance on the agreed design, Susan is planning to purchase a European L-shaped sofa made in Spain from iFurniture, a furniture company, for HK$25,000. Susan just see the sofa set from iFurniture's catalogue, she says that she would very much like to view the real sofa but that she is out of town on a five-day business trip and will not be able to view it until she returns. The boss of iFurniture, Lucas says that if another buyer comes forward, he will have to sell the sofa to that buyer. Susan says she will pay HK$2,500 if iFurniture promises not to sell the sofa to another buyer for the next five days. Lucas agrees to this. Analyse whether any contract has been made between the parties and, if so, what are its terms? Refer to the relevant case law to support your answer.

(4) Harry completes the contracted design work, but Susan only pays HKS300,000, instead of the HKS500,000 originally agreed. Advise Harry of his legal position.

Consider the two (excess return) index-model regression results for stocks A and B. The risk-free rate over the period was 5%, and the market’s average return was 13%.
