In computer science, a call stack is a stack data structure that contains information about the active subroutines of a computer program.
What is a call stack?
An mediator (like the JavaScript interpreter in a web browser) uses a call stack to keep track of its situation in a narrative that calls numerous functions, including which function is currently being executed and which processes are being called from within it, among other things.When a function is called by a script, the interpreter adds the call to the call stack and starts the function's execution.Any performs that this function calls are decided to add to the call stack further down and are executed where their calls are made.When the current function is finished, the interpreter deletes it from the stack and continues where it left off in the previous code listing.To know more about JavaScript check the link below:

A method signature for a method consists of all elements of the method except the body. That is, a method signature consists of the privacy, (non-)static, return datatype, method name, and formal parameters. Consider the ceiling method as an example.
public static int ceiling (double num)
{
return num <= 0 ? (int) num: (int) num + 1;
}
The method signature of the ceiling method is the first line of the method: public static int ceiling (double num). In this example, we note that ceiling is static because it is a standalone method and does not require an object to invoke (since we are not acting on an instance of a class).
For parts a - d, give the method signature described by the scenario.
a) A method in class String that returns the reversed version of the current String.
b) A method that returns the maximum of two given integers.
c) A method that returns true or false if the input integer is an even number.
d) A default constructor for class Table.

BONUS QUESTION WORTH 100!!
no links please and no copying and pasting .I will report you and you will be given a warning.
only answer if you know this please!.
Your Assignment, Part I
You decide that you want to open a flower shop. You want to sell premade arrangements, custom arrangements, bouquets containing either one or two types of flowers, and individual flowers.
Before you can open a shop though, you need to make sure your personal finances are in order. You can use spreadsheets in order to do this.
Submit any spreadsheets you create to your instructor at the end of this project.
1. Imagine you have $15,000 saved in a personal account to help supplement your income during the first year your business is open. Per month, the rent on your current apartment is $500, utilities are generally about $45, gas for your car is about $120, and food costs are about $350. In September, you know your rent will increase to $525 per month. Create a budget that divides the $15,000 across these categories for a full year. If there is any extra money, include that in your budget.
2. With your personal finances taken care of, you feel prepared to open your flower shop. You secure a small business loan for $60,000. You want to spend $30,000 of that loan renovating the space for your shop and $15,000 on equipment needed to store the flowers and create arrangements. Rent will be $700 per month or $4,200 for the first six months the shop is open and utilities will be approximately $76 per month or $456 for the first six months. You also want to spend $2,000 on flowers and supplies to stock the shop for the first month and $600 per month for the next five months to restock flowers and greenery.
a) Create a budget for the shop’s opening with this information.
b) Looking at these numbers in the spreadsheet starts to get a little overwhelming. You want to be able to look quickly at a chart and have a good idea of how much of your loan will be used in the first month of opening the business. What type of graph or chart would work best for this?
c) Create the graph or chart that will best show how you spent your loan in the first month of opening the business.
3. The shop has been open for a week now and you need to work on the first payroll for your two employees, Sean and Justine. Sean’s hourly pay is $8.25. He worked 10 hours this week and is taxed at a 5% rate. Justine’s hourly pay is $9.00. She worked 30 hours this week and is taxed at a 6% rate.
a) Create a spreadsheet for your payroll. Make sure you use a formula to automatically calculate Total Pay.
b) Did you use conditional formatting on any of the cells? If so, which ones? Explain why.
4. After working on payroll, you decide to take inventory of what’s in the shop because your next order date is coming up soon. You will just focus on your inventory of flowers.
a) Use the following information to create your inventory record:
254 red roses currently; 48 sold this week
102 yellow roses currently; 12 sold this week
40 pink hydrangeas currently; 3 sold this week
164 white daisies currently; 52 sold this week
132 yellow daisies currently; 48 sold this week
144 orange daisies currently; 18 sold this week
86 pink lilies currently; 4 sold this week
102 white peonies currently; 24 sold this week
98 pink peonies currently; 36 sold this week
b) If your current rate of sales continues, in how many weeks will you run out of pink peonies and red roses, assuming that all flowers remain fresh? Use your spreadsheet to calculate the answer.
5. Kimberly Melville comes in wanting to order a personalized flower arrangement. She wants an arrangement with 10 white daisies, 4 white peonies, and 2 pink lilies. White daises are $1 each, white peonies are $2.75 each, and pink lilies are $4 each. Kimberly also chooses a vase that costs $14.00. Each of these items is taxable, and the tax rate is 7.5%. You write down her address as 300 Starlight Court, Baltimore MD, 21228. Create an invoice for this order.
6. Three months after the shop first opens, you want to create an up-to-date balance sheet to see how the company is doing financially in its first quarter (January through March). Use the information below to create your balance sheet.
Your current assets include:
$3,546 for Accounts Receivable (from invoices)
$15,000 for Equipment
$3,200 for Inventories
$678 for Cash
Your current liabilities include:
$3,200 for Accounts Payable
$4,200 for Wages
$300 for Taxes Payable
Total expenses for the year: $12,280
The Budget PlanBased on the information provided, here's a budget plan that divides the $15,000 across the categories mentioned:
Rent:
$500 x 8 months = $4,000
$525 x 4 months = $2,100
Total rent expenses = $6,100
Utilities:
$45 x 12 months = $540
Gas:
$120 x 12 months = $1,440
Food:
$350 x 12 months = $4,200
Total expenses for the year: $12,280
With $15,000 in savings, this leaves $2,720 for unexpected expenses, emergencies, or any other miscellaneous costs that may arise throughout the year.
It's always a good idea to have some extra funds available in case of unforeseen circumstances, so this budget plan provides a cushion for those situations.

3.Personal Information Class
Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Demonstrate the class by writing a java
program that creates three instances of it. One instance should hold your information, and
the other two should hold your friends' or family members' information.
Here's an example Java class that holds personal data and provides accessor and mutator methods:
public class PersonalData {
private String name;
private String address;
private int age;
private String phoneNumber;
public PersonalData(String name, String address, int age, String phoneNumber) {
this.name = name;
this.address = address;
this.age = age;
this.phoneNumber = phoneNumber;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
}
And here's an example Java program that creates three instances of this class:
public class PersonalDataDemo {
public static void main(String[] args) {
PersonalData myData = new PersonalData("John Smith", "123 Main St, Anytown USA", 35, "555-1234");
PersonalData friend1Data = new PersonalData("Jane Doe", "456 Oak St, Anytown USA", 28, "555-5678");
PersonalData friend2Data = new PersonalData("Bob Johnson", "789 Elm St, Anytown USA", 42, "555-9012");
System.out.println("My personal data:");
System.out.println("Name: " + myData.getName());
System.out.println("Address: " + myData.getAddress());
System.out.println("Age: " + myData.getAge());
System.out.println("Phone number: " + myData.getPhoneNumber());
System.out.println();
System.out.println("Friend 1's personal data:");
System.out.println("Name: " + friend1Data.getName());
System.out.println("Address: " + friend1Data.getAddress());
System.out.println("Age: " + friend1Data.getAge());
System.out.println("Phone number: " + friend1Data.getPhoneNumber());
System.out.println();
System.out.println("Friend 2's personal data:");
System.out.println("Name: " + friend2Data.getName());
System.out.println("Address: " + friend2Data.getAddress());
System.out.println("Age: " + friend2Data.getAge());

Find the basic period and basic frequency of the function g(t)=8cos(10πt)+sin(15πt)
Answer:
The period is
\(\frac{2\pi}{5} \)
The frequency is
\( \frac{5}{2\pi} \)
Explanation:
The period of both functions will be LCM of both period.
The period of cos is
\( \frac{\pi}{5} \)
The period of sin is
\( \frac{2\pi}{15} \)
Let convert each into degrees.
\( \frac{\pi}{5} = 36\)
\( \frac{2\pi}{15} = 24\)
Find the least common multiple between 36 and 24, which is 72.
Convert 72 into radians
\(72 = \frac{2\pi}{5} \)
The period is 2pi/5.
The frequency is equal to
1/period.
so the frequency is
\( \frac{1}{ \frac{2\pi}{5} } = \frac{5}{2\pi} \)

The Classic Triangle Testing Problem, (Myer's Triangle): A program reads three integer values. The three values are interpreted as representing the lengths of the sides of a triangle. The program prints a message that states whether the triangle is scalene, isosceles, or equilateral. Develop a set of test cases (at least 6 ) that you feel will adequately test this program. (This is a classic testing problem and you could find numerous explanations about it on the internet. I would recommend that you try to submit your own answer, based on your understanding of the topic)
Let’s define what the three different types of triangle requirements for the side’s lengths are:______.
Answer:
Here is the Python program:
def MyersTriangle(a, b, c): #method to test triangles
if not(isinstance(a, int) and isinstance(b, int) and isinstance(c, int)): #checks if values are of type int
return 'Enter integer values'
elif a==0 or b==0 or c==0: #checks if any value is equal to 0
return 'Enter integer values greater than 0'
elif a<0 or b<0 or c <0: #checks if any value is less than 0
return 'All values must be positive'
elif not (a+b>=c and b+c>=a and c+a>=b): #checks if triangle is valid
return 'Not a valid triangle'
elif a == b == c: #checks if triangle is equilateral
return 'triangle is equilateral'
elif a == b or b == c: #checks if triangle is isoceles
return 'triangle is isoceles'
elif a != b and a != c and b != c: #checks if triangle is scalene
return 'triangle is scalene'
#test cases
print(MyersTriangle(2.4,7.5,8.7))
print(MyersTriangle(0,0,0))
print(MyersTriangle(-1,5,4))
print(MyersTriangle(10,10,25))
print(MyersTriangle(5,5,5))
print(MyersTriangle(3,3,4))
print(MyersTriangle(3,4,5))
Explanation:
The program uses if elif conditions to check:
if the values are integers: this is checked by using isinstance method that checks if values belongs to a particular int. If this returns true then values are integers otherwise not
if values are not 0: this is checked by using logical operator or between each variable which checks if any of the values is 0
if values are not negative: This is checked by using relational operator < which means the values are less than 0
if values make a valid triangle: this is checked by the rule that the sum of two sided of the triangle is greater than or equal to the third side.
and then checks if the triangle is scalene, isosceles, or equilateral: This is checked by the following rules:
For scalene all three sides are unequal in length
For isosceles any of the two sides are equal in length
For equilateral all sides should be equal in length.
