Write a method named numUnique that accepts a sorted array of integers as a parameter and that returns the number of unique values in the array. The array is guaranteed to be in sorted order, which means that duplicates will be grouped together. For example, if a variable called list stores the following values: int[] list
Answer:
The method in Java is as follows:
public static int numUnique(int list[]) {
int unique = 1;
for (int i = 1; i < list.length; i++) {
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j])
break;
}
if (i == j)
unique++;
}
return unique;
}
Explanation:
This line defines the numUnique method
public static int numUnique(int list[]) {
This initializes the number of unique elements to 1
int unique = 1;
This iterates through the list
for (int i = 1; i < list.length; i++) {
The following iteration checks for unique items
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j]) If current element is unique, break the iteration
break;
}
if (i == j)
unique++;
}
This returns the number of unique items in the list
return unique;
}
Write a program that takes a first name as the input, and outputs a welcome message to that name.
Ex: If the input is Pat the output is:
Hello Pat and welcome to cs Online
Input Welcome message
1 user_name = input 2 3
Type your code here
Answer:
The program in Python is as follows:
user_name = input("Name: ")
print("Hello "+user_name+" and welcome to cs Online")
Explanation:
The program is written in Python, and it uses basic input and output function to execute the instruction in the question.
First: Prompt the user for username
This is done in the following line
user_name = input("Input your name: ")
Next, the print function is used to output the welcome message
print("Hello "+user_name+" and welcome to cs Online")
The program that takes first name as the input, and outputs a welcome message to that name is represented below:
user_input = str(input("please type your first name: "))
print(f" Hello {user_input} !! Welcome to CS online ")
The code is written in python.
The variable user_input is used to store the user's input. It ask the user for his/her first name and store it.
Then we print the welcome statement using the f string.
F-string are use to combine strings and variables.

The CG would move toward the nose.
O The CG would move lower
Answer:
the CG would move toward the rear.
Explanation:
Adding a paper clip to the vertical stabilizer of your glider will, the CG would move toward the rear. The correct option is A.
What is center of gravity?The place on an item where the force of gravity is thought to act is known as the center of gravity (CG).
The gravitational pull is thought to be focused at the point where an object weighs on average. Depending on the object's size, shape, and mass distribution, the center of gravity will be in one place or another.
The impact of adding a paper clip to your glider's vertical stabilizer is to shift the center of gravity (CG) to the back of the glider.
This is due to the fact that the paper clip adds weight to the glider's rear, moving the center of mass there and, as a result, the center of gravity.
Thus, the correct option is A.

In this program we are going to practice using the Math class by computing some important values on the unit circle. Starting at 0 and going up by
PI/4 radians (or 45 degrees), print out information of the format below.
Radians: (cos, sin)
0.0: 1.0, 0.0
0.79: 0.7, 0.71
1.57: 0.0, 1.0
2.36: -0.71, 0.7

3.93: -0.7, -0.71
4.71: 0.0, -1.0
5.5: 0.71, -0.71
Hints:
You’ll need to use the Math.sin, Math.cos methods
and the Math.PI constant!
You’ll also need to loop from 0 to 2*PI
You can round a decimal to 2 decimal places by multiplying by 100, rounding to the nearest int, and then dividing by 100. Here’s an example:
double value = 0.431675;
value = value * 100; // 43.1675
value = Math.round(value) // 43.0
value = value / 100.0; // 0.43
// Or put it all on one line:
value = Math.round(value * 100) / 100.0;
Answer:
The program in Java is:
import java.lang.*;
public class MyClass {
public static void main(String args[]) {
for(int i= 0;i<360;i+=45){
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
System.out.println(angle+": "+cosX +" "+ sinX);
}
}
}
Explanation:
This line iterates through the angles from 0 to 360 or 0 to 2*Pi
for(int i= 0;i<360;i+=45){
This calculates the angle to radians
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
This calculats the cosine of the angle rounded to 2 decimal place
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
This calculats the sine of the angle rounded to 2 decimal place
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
This prints the required output
System.out.println(angle+": "+cosX +" "+ sinX);

Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.

public class WeatherSnapshot
{
private int tempInFahrenheit;
private int humidity; // value of 56 means 56% humidity
private int dewPoint; // in degrees Fahrenheit
private String date; // stores the date as a String
private int time; // in military time, such as 1430 = 2:30 pm
private boolean cloudy; // true if 25% or more of the sky is covered
// constructor not shown, but it initializes all instance variables
// postcondition: returns temperature
public int getTemp()
{
return tempInFahrenheit;
}
// postcondition: returns date
public String getDate()
{
return date;
}
// postcondition: returns true if precipitation is likely; false otherwise
public boolean precipitationLikely()
{
// implementation not shown
}
// other methods not shown
}
Suppose a WeatherSnapshot object named currentWeather has been correctly instantiated in a client class. Which of the following will correctly call the precipitationLikely method?
A. boolean couldRain = precipitationLikely();
B. boolean couldRain = currentWeather.precipitationLikely();
C. boolean couldRain = currentWeather.precipitationLikely(true);
D. double percentChanceOfRain = precipitationLikely();
E. double percentChanceOfRain = currentWeather.precipitationLikely();
Answer:
The answer is "Option b".
Explanation:
In this question, It took the boolean parameter, which may use the couldRain as the precipitationLikely precipitation method as the boolean variable because the precipitationLikely is not a static type, and it can name this method utilizing object is called currentWeather, that's why the choice b is correct.

A drink costs 2 dollars. A taco costs 3 dollars. Given the number of each, compute total cost and assign totalCost with the result. Ex: 4 drinks and 6 tacos yields totalCost of 26.
*/
int main() {
int numDrinks = 0;
int numTacos = 0;
int totalCost = 0;
numDrinks = 4;
numTacos = 6;
/* Your solution goes here */
totalCost = (2 * numDrinks) + (3 * numTacos);
cout << "Total cost: " << totalCost << endl;
return 0;
}
Answer:
See Explanation
Explanation:
The question has been answered; however, the program is not dynamic enough because the output will always be 26.
To make it dynamic, replace the following lines of code:
numDrinks = 4;
numTacos = 6;
with:
cout<<"Number of drinks: ";
cin>>numDrinks;
cout<<"Number of Tacos: ";
cin>>numTacos;
The above lines of code will let the user input different values for numDrinks and numTacos each time the program is executed.
Computing the total cost using code can be represented as follows:
def total_cost(no_of_drinks, no_of_talcos):
totalCost = 2*no_of_drinks + 3*no_of_talcos
return totalCost
print(total_cost(4, 6))
Python code explanation:A function named total_cost is declared and it accept the parameters no_of_drinks and no_of_talcos.
The totalCost is used to store the result of the cost of the total drinks and tacos bought in dollars.
Then, we return the totalCost.
Finally, we use the print statement to call the function with its required parameters.

for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){

}
}
This code will create an infinite loop. Why does it create an infinite loop?
Answer:
Explanation:
This code creates an infinite loop because it is detecting that the first value of copyNums is 1, therefore it runs the insertItem code. This code then adds the value "hello" to the array in position i which would be 0. Then moves to the next value of the array, but since the element "hello" pushed the value 1 to the next index then the code just repeats itself with the same value of 1. This continues to happen because every time the value "hello" is added it simply pushes the 1 to the next index and repeats the same code.
Answer:
[tex]var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];
