3. Data from the Rand Health Insurance Experiment indicated that:

1. price has no impact on the utilization of health care.
2. increased price is related to increased use of health care.
3. increased price is related to decreased use of health care.
4. increased price first increases, then decreases use of health care.
5. None of the above.

Swayamvar

Problem Description

A ceremony where a Bride chooses her Groom from an array of eligible bachelors is called Swayamvar. But this is a Swayamvar with difference. An array of Bride-to-be will choose from an array of Groom-to-be.

The arrangement at this Swayamvar is as follows

· Brides-to-be are organized such that the most eligible bachelorette will get first chance to choose her Groom. Only then, the next most eligible bachelorette will get a chance to choose her Groom

· If the initial most eligible bachelorette does not get a Groom of her choice, none of the Brides-to-be have any chance at all to get married. So unless a senior bachelorette is out of the “queue”, the junior bachelorette does not get a chance to select her Groom-to-be

· Inital state of Grooms-to-be is such that most eligible bachelor is at the head of the “queue”. The next most eligible bachelor is next in the queue. So on and so forth.

· Now everything hinges on the choice of the bachelorette. The most eligible bachelorette will now meet the most eligible bachelor.

· If bachelorette selects the bachelor, both, the bachelorette and the bachelor are now Bride and Groom respectively and will no longer be a part of the Swayamvar activity. Now, the next most eligible bachelorette will get a chance to choose her Groom. Her first option is the next most eligible bachelor (relative to initial state)

· If the most eligible bachelorette passes the most eligible bachelor, the most eligible bachelor now moves to the end of the queue. The next most eligible bachelor is now considered by the most eligible bachelorette. Selection or Passing over will have the same consequences as explained earlier.

· If most eligible bachelorette reaches the end of bachelor queue, then the Swayamvar is over. Nobody can get married.

· Given a mix of Selection or Passing over, different pairs will get formed.

The selection criteria is as follows

1. Each person either drinks rum or mojito. Bride will choose groom only if he drinks the same drink as her.

Note : There are equal number of brides and grooms for the swayamvar.

Tyrion as the hand of the king wants to know how many pairs will be left unmatched. Can you help Tyrion?

Constraints

1<= N <= 10^4

Input Format

First line contains one integer N, which denotes the number of brides and grooms taking part in the swayamvar. Second line contains a string in lowercase, of length N containing initial state of brides-to-be. Third line contains a string in lowercase, of length N containing initial state of grooms-to-be. Each string contains only lowercase 'r' and 'm' stating person at that index drinks "rum"(for 'r') or mojito(for 'm').

Output

Output a single integer denoting the number of pairs left unmatched.

Timeout

1

Explanation

Example 1

Input

4

rrmm mrmr

Output

0

Explanation

The bride at first place will only marry groom who drinks rum. So the groom at first place will join the end of the queue. Updated groom's queue is "rmrm".

Now the bride at first place will marry the groom at first place. Updated bride's queue is "rmm" and groom's queue is "mrm".

The process continues and at last there are no pairs left. So answer is 0.

Example 2

Input

4 rmrm mmmr

Output

2

Explanation

Following the above process 2 pairs will be left unmatched. Remember that bride will not move until she gets a groom of her choice.

USING MATLAB
Where indicated in the script below, write a function, called myflip, which accepts one vector v (either a column or a row) and outputs the same vector v of the same dimensions, but with the values in reverse order (use MATLAB function flip()). In other words, v will be overwritten by its flipped version. In your function, you may only use length() and floor(). You only need one loop.

%this code tests the function, myflip, which you will write below

v1 = 100*rand(1);

v1 = myflip(v1)

n = randi([2 100], 1, 1);

v2 = 100*rand(1,2*n);

v2 = myflip(v2)

n = randi([2 100], 1, 1);

v3 = 100*rand(2*n+1,1);

v3 = myflip(v3)

South Africa is proposing a project that will increase sugar cane production in the country. South Africa is a net exporter of sugar cane and exports to the UK. Assume the following: • The CIF at Liverpool, UK is £360 per ton • Freight, insurance and unloading from Cape Town, a South African port to Liverpool is £15 per ton • Local port charges at South Africa is 150 Rand per ton • Transport and marketing costs from warehouse to the port in Cape Town is 120 Rand per ton • Storage, transport and marketing cost from point of production to warehouse is 50 rand per ton • No export taxes • The Exchange rate is £1= 12 rands Where the rand is the South African currency and £ is the British Pound Sterling Answer the following questions

a) Estimate the FOB price at the Cape Town port in South Africa in £

b) Estimate the FOB price in Rands

c) Estimate export parity price at a warehouse in South Africa

d) Estimate the export parity price at farm gate in South Africa.

For this project, you will create a program in C that will test the user’s proficiency at solving different types of math problems.   The program will be menu driven. The user will select either addition, subtraction, multiplication or division problems. The program will then display a problem, prompt the user for an answer and then check the answer displaying an appropriate message to the user whether their answer was correct or incorrect. The user will be allowed 3 tries at each problem. The program will also keep statistics on how many problems were answered correctly.

This week you will add functions to allow the user to select problems of varying degrees of difficulty and also keep statistics on number of correct answers vs. total number of problems attempted.

So now let’s add the code for the remaining functions:

We’ll start by inserting code to ask the user if they want to see problems that are easy, medium or difficult. We’ll do this by prompting them to enter ‘e’ for easy, ‘m’ for medium or ‘d’ for difficult and we’ll do this right after they have selected the type of problems they want. We will also add a validation loop that will check to see if they entered a correct response (e,m, or d).

Easy – problems using numbers 0 thru 10

Medium – problems 11 thru 100

Difficult – problems 100 – 1000

Here’s some code to get you started on the “difficulty level.”

if( difficultyLevel == 'E')

    {

                num1=rand()%10+1;

                 num2=rand()%10+1;

    }

   else

     if (difficultyLevel == 'M')

                {num1=rand()%100+1;

                 num2=rand()%100+1;

                }

   else

                 { num1=rand()%1000+1;

                 num2=rand()%1000+1;}           

Use an “if” statement to check the difficulty and generate the random numbers.

Statistics:

Create two variables ttlProblems and correctAnswers. Every time the user answers a problem add 1 to ttlProblems and every correct answer add 1 to correctAnswers. We’ll display the total number of problems and correct answers as well as the percent correct after the user has selected the exit option on the main menu.  

Then, alter the code to allow for floating point numbers. This requires formatting the output.

Inside “Lab1”folder, create a project named “Lab1Ex1”. Use this project to write and run a C++ program that produces:  Define a constant value called MAX_SIZE with value of 10.  Define an array of integers called Class_Marks with MAX_SIZE which contains students Mark. Define a function called “Fill_Array” that takes an array, and array size as parameters. The function fills the odd index of the array randomly in the range of [50- 100] and fills the even index of the array using input from user. The valid input values are between 50-100.

Hint: To get random number you can use rand() function: min + rand()%(max-min+1)  Fill the array by calling Fill_Array function

How would I add a quickSort function to the below C++ code to sort the randomly generated numbers?

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;
int i;
int array[10];
int odd;
int Max;
int counter = 0;

int main()

{
cout << "The 10 random elements are: ";
cout << endl;

srand ( time(0) );

for (int j = 0; j < 99; j++)
{
    i = rand() % 100;
    if (i != i - 1)
    array[j] = i;

else
{
    i = rand() % 100;
    array[j] = i;
}


}

for (int k = 0; k < 10 ; k++)
{
    cout << array[k] << "\n";

}

cout << endl;


return 0;
}

You are comparing the regression output across two publicly-traded companies. Both regressions were run using monthly data for 5 years and against the S&P500 with the returns on each company’s stock as the independent variable.

1.If the implied equity risk premium with a constant dividend growth rate and based on a broad U.S. stock market index is equal to 8% and the risk-free rate is 2%, what is the required return of an investor in Nero Cannery? Rand Foods?

2. You just found out that even though Rand Foods is incorporated in the U.S. it gets 100% of its revenues from Mexico. Is it appropriate to use an implied equity risk premium based on a U.S. stock market index for calculating an investor’s required return in Rand? Why or why not? If the Mexican government bond rating is A3 (not default-free), how will you approach the estimation of the ERP, i.e. what method will you use and what information do you need?

3. Is the regression above an “excess returns” regression or a “raw returns” regression? Explain.

(4) Interpret the R² and intercept for Rand Foods.
