Have you ever been in a situation in which you forgot a password and had a difficult time retrieving it? If so, in just a few sentences, write about how it made you feel and what you would do differently next time. If this has never happened to you, write about what you would do to keep track of the many passwords you use.

In Java, write a program that solves the following problem.

An arena can seat 12,000 people for an event. If the arena was full and you were to poll everyone for which day of the year (between 1 and 365, inclusive) they were born, determine which days had the most birthdays and which days had the fewest birthdays.

Write a program that will generate 12,000 random birthdays (integer numbers) between 1 and 365 and count how many people have that same birthday. Output a listing of the days that have the most birthdays and the days that have the fewest birthdays. You do not need to convert a number like 32 to an actual date (February 1^st).

Do NOT change your class name from "Main". Your filename should be "Main.java".

Your code will have two classes:

• the Main class will hold the main() method.
  • From this class, you will create an object of the Arena class.
  • This object will call responsible methods in the Arena class to print the MAX and MIN birthday dates.
• the Arena class will have a random number generation method.
  • This class's constructor will take #of people in the area as an input.
  • With this number, you will create an array and a method will put random numbers between 1 and 365 in this array.
  • Two other methods in this class will determine the days with MAX and MIN birthdays.
  • Make sure to print ALL maximum and minimum birthdate days.

The two classes can be part of the same file. A naive example structure is shown below.

public class Main{

public static void main(String args[]){
Arena a = new Arena();
a.printArena();
}
}

class Arena{
void printArena() {
System.out.println("I am arena");
}
}

Sample Output

The following days have 75 people:

147

The following days have 35 people:

143 312

Matlab Program

First, create a class object named SequenceMap that has as private data members the following two:

string recognition_sequence_ ;

vector enzyme_acronyms_;

Other than the big-five (note that you can use the defaults for all of them), you have to add the following:

a) A constructor SequenceMap(const string &a_rec_seq, const string &an_enz_acro),that constructs a SequenceMap from two strings (note that now the vector enzyme_acronyms_ will contain just one element, the an_enz_acro).

b) bool operator<(const SequenceMap &rhs) const, that operates based on the regular string comparison between the recognition_sequence_ strings (this will be a one line function).

c) Overload the operator<< for SequenceMap.

d) void Merge(const SequenceMap &other_sequence). This function assumes that the object’s recognition_sequence_ and other_sequence.recognition_sequence_ are equal to each other. The function Merge() merges the other_sequence.enzyme_acronym_ with the object’s enzyme_acronym_. The other_sequence object will not be affected.

Please test it with your own test functions to make sure that it operates correctly.

Please also show the test functions that you utilize so I can also implement it.

thank you.

IsEqualToTest (30)

Write a simple generic version of method isEqualTo that compares its two arguments with the equals method and returns true if they’re equal and false otherwise. Use this generic method in a program that calls isEqualToTest with the built-in types Integer, String, Double and Object. The main reads in two Integer, and two Double values with autoboxing, as well as two String and calls the method. For Object just create two Object objects with no parameters. The method doesn’t need to include any correctness tests.

Lab 4-2: Computing Tax

The United States federal personal income tax is calculated based on filing status and taxable income. There are four filing statuses: single filers, married filing jointly, married filing separately, and head of household. The tax rates vary every year. Table 3.2 shows the rates for 2009. If you are, say, single with a taxable income of $10,000, the first $8,350 is taxed at 10% and the other $1,650 is taxed at 15%. So, your tax is $1,082.5.

Table 1

2009 U.S. Federal Personal Tax Rates

You are to write a program to compute personal income tax. Your program should prompt the user to enter the filing status and taxable income and compute the tax. Enter 0 for single filers, 1 for married filing jointly, 2 for married filing separately, and 3 for head of household.

Here are sample runs of the program:

Sample 1:

Enter the filing status: 0

Enter the taxable income: 100000

Tax is 21720.0

Sample 2:

Enter the filing status: 1

Enter the taxable income: 300339

Tax is 76932.87

Sample 3:

Enter the filing status: 2

Enter the taxable income: 123500

Tax is 29665.5

Sample 4:

Enter the filing status: 3

Enter the taxable income: 4545402

Tax is 1565250.7

**C++ only, standard library.

We are supposed to create a tower of hanoi program and do a sequence of 100 disks. We are supposed to run the program and then answer two questions:

1) How long does your computer take to run(time)?

2) If I could move 1 disk per second how long would it take?

Here is my program so far:

void towerOfHanoi(int numDisks, char from_rod, char to_rod, char aux_rod)
{
int count=0;
if (numDisks == 1)
{
//cout << "Move disk 1 from rod " << from_rod <<
// " to rod " << to_rod<<endl;
return;
}
towerOfHanoi(numDisks - 1, from_rod, aux_rod, to_rod);

//cout << "Move disk " << numDisks << " from rod " << from_rod <<
//" to rod " << to_rod << endl;
towerOfHanoi(numDisks - 1, aux_rod, to_rod, from_rod);
}
  
// Driver code
int main()
{
int numDisks; // Number of disks
  
cout<<"This program solves the Hanoi Tower puzzle"<<endl<<endl;
  
cout<<"Enter the number of disks to calculate: ";
cin>>numDisks;
  
towerOfHanoi(numDisks, 'A', 'C', 'B'); // A, B and C are names of rods
return 0;
}
  

What code would I add to the following program to have it print out the runtime each time the program is used?

def moveTower(n, source, dest, temp):
if n == 1:
print("Move disk from", source, "to", dest+".")
else:
moveTower(n-1, source, temp, dest)
moveTower(1, source, dest, temp)
moveTower(n-1, temp, dest, source)

def hanoi(n):
moveTower(n, "A", "C", "B")

def main():
print("Towers of Hanoi")
n = int(input("How many disks? "))
moveTower(n, "A", "C", "B")

if __name__ == '__main__': main()
