Hi it's the java stack to convert from infix to postfix

If I want to fix this code to calculate each numbers not just displaying the numbers what should I do?

Would you help me to fix the result?

Real Shocks and the ‘Keynesian Cross’

Suppose the economy of Canada has reached the long-run equilibrium (i.e. full employment) and assume that the function of exports and imports are as follows:

(1) EX =α0 +α1q+α2(Y∗ −T∗)

(2) IMP =β0 −β1q+β2(Y −T)

where q is the real exchange rate between Canadian and US goods, Y − T is the Canadian disposable income, Y ∗ − T ∗ is the US disposable income, and the α’s and the β’s are positive parameters.

Assume that Prime Minister Trudeau decides to implements a temporary policy that convinces Canadians to buy less imported goods at any given real exchange rate and any given level of disposable income. In particular, assume that this policy lowers β0 in the import function shown above.

Explain how this temporary shock affects the level of output, consumption, investment, government expenditure, the nominal interest rate, the nominal and real exchange rates, and the level of prices in the short run. Use the AA-DD model to answer this question and do not forget to use a diagram to support your answer.

JAVA

Implement and test the following static recursive methods.

1) DigitCount – find the sum of the digits in an integer digitCount(12345) would be 5

2) Power2 - Efficiently compute exponentiation for non-negative exponents by the following recursive algorithm:

bx = 1 if x == 0

bx = (b(x/2))2 if x is even bx = b * (b(x-1)) if x is odd

3) Write a recursive method isBackwards that has two String parameters and returns true if the two Strings have the same sequence of characters but in the opposite order (ignoring white space and capitalization), and returns false otherwise. The method should throw an IllegalArgumentException if either String is null.

Test this method with following examples, isBackwards("Fried", "deirf") -> true isBackwards("Sit", "Toes") -> false isBackwards("", "") -> true

isBackwards("I madam", "mad am I") -> true

Using the following text string: axcbramneltodaydy

Search for the following pattern: 'today' Specify whether or not you found the pattern. The minimum requirement is to use the string STL, the brute force method and hard code both the text and the pattern.

For extra credit, you can add any of the following:

1. Do not use the string STL.

2. Allow me to enter both the text string and the pattern, including spaces. You can designate a special end-of-text character for me to include.

3. Use the Boyer-Moore algorithm instead of brute force.

4. Identify the location where the pattern was found within the text.

5. Allow for the possibility that the pattern can appear more than once in the text and identify all of the locations where the pattern was found.

A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 83.2 N at an angle of 28.0° above the horizontal. The box has a mass of 20.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (Indicate the direction with the sign of your answer.)

(a) Find the acceleration of the box. (Assume that the +x-axis is to the right and the +y-axis is up along the page.)

(b) The student now starts moving the box up a 10.0° incline, keeping her 83.2 N force directed at 28.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box? (Assume that the +x-axis is along the incline and the +y-axis is upwards and perpendicular to the incline.)

Questions regarding the lab: Spectrophotometric Determination of Caffeine in a Soft Drink

1)How are the absorption spectra of atoms and molecules the same, and how are they different?

2)Beer’s law, A=e b c forms the basis of a calibration curve. It clearly shows that there is a theoretically linear relationship between absorbance and concentration under constant conditions of analyte absorptivity (e) and path length (b). However, it is important for an analyst to be aware that there are limitations analyte concentration range under which there truly is a linear relationship between absorbance and concentration. Under what conditions of concentration does the linear relationship break down?

3)Caffeine is not fluorescent. However, just for argument’s sake imagine that it was fluorescent. Would the wavelength of maximum fluorescence be shorter, longer, or equal to the wavelength of maximum absorbance? Why?

4)Why was it necessary to remove CO2 before the analysis?

Hi, how can I create a random guessing game in C++ with 2 players. I got some of the code but not working properly.

//Guess my number game
#include <iostream>
#include <ctime>
using namespace std;

int main()

{
   int seed = time(0);
   srand(seed);
   int randomNumber = rand() % 100 + 1;
   int userInput1, userInput2;
   int counter = 0;

   cout << "Welcome to Guess my Number" << endl;

   do
   {
       cout << "PLAYER1 enter a number: ";
       cin >> userInput1;
       cout << "PLAYER2 enter a number: ";
       cin >> userInput2;

       if (userInput1 == randomNumber)
           cout << "Congratulations you WON!" << endl;

       else if (userInput1 > randomNumber)
           cout << "Winning number is lower." << endl;

       else
           cout << "Winning number is higher." << endl;

       counter++;
       cout << endl;

   } while (userInput1 != randomNumber);

   cout << "The winning number was " << randomNumber << endl;
   cout << "Number of attempts. " << counter << endl;

   system("pause");
   return 0;
}

A long solenoid has 110 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.50 cm perpendicular to the solenoid axis. The speed of the electron is 0.040 c (c = speed of light). Find the current i in the solenoid.

Use the function from Q1 to find the sum of ints,n, from 1 to 2500,

inclusive, that satisfy the following boolean:

     ((n div by 11) and ( n is div by 13) ) or (n is div by 61)

Print out the sum with a labelled print:

The sum of qualifying ints, n, 1 <= n <= 2500, is ___________.

Hint: Remember that you can use a for loop to traverse a list.

For example:

L = [23,37,41,53,61]:

for n in L:

    print(n, end = ' ')

23 37 41 53 61

>>>

You can do this even more easily if you use the BIF sum, which returns the sum

of the numbers in a list

L1 = [2,7,13]

Sum = sum(L1)

print(Sum)

Write code to find the product of every 19th qualifying int (19th, 38th,...) from Q2, then

print out a labelled print:

The product of every 19th qualifying int is ____________

Then write code to find the sum of every 2nd qualifying int (2nd,4th,...) from Q2, then

print out a labelled print:

The sum of every 2nd qualifying int is ______________

Hint: Set up a counter and initialize the counter to zero.

Increase the counter as the ints from the list returned from Q2 are traversed.

Do not use indices - just use what has been taught. You can tell from the

counter what qualified int you are currently on. Knowing this, you can determine if

you are on a 2nd or a 19th qualifying int.

What is the largest int times the sum that is less than or equal to the product?

Print this out with a labelled print statement:

The largest int times the sum that is less that or equal to the product is _____________.
