Explanation:
What is the output of the following code snippet? int s1 = 20; if (s1 <= 20) { System.out.print("1"); } if (s1 <= 40) { System.out.print("2"); } if (s1 <= 20) { System.out.print("3"); }
Answer:
The program outputs 123
Explanation:
The first line of the program initializes s1 to 20
The second line checks if s1 is less than or equal to 20.
This is true,
So, 1 is printed
The third line checks if s1 is less than or equal to 40.
This is true,
So, 2 is printed
The fourth line checks if s1 is less than or equal to 20.
This is true,
So, 3 is printed
Hence, the output is 123
The Fast as Light Shipping company charges the following rates. Weight of the item being sent Rate per 100 Miles shipped 2kg or less. $0.25 Over than 2 kg but not more than 10 kg $0.30 Over 10 kg but not more than 20 kg. $0.45 Over 20 kg, but less than 50kg. $1.75 Write a program that asks for the weight of the package, and the distance to be sent. And then displays the charge.
Answer:
weight = float(input("Enter the weight of the package: "))
distance = float(input("Enter the distance to be sent: "))
weight_charge = 0
if weight <= 2:
weight_charge = 0.25
elif 2 < weight <= 10:
weight_charge = 0.3
elif 10 < weight <= 20:
weight_charge = 0.45
elif 20 < weight <= 50:
weight_charge = 1.75
if int(distance / 100) == distance / 100:
d = int(distance / 100)
else:
d = int(distance / 100) + 1
total_charge = d * weight_charge
print("The charge is $", total_charge)
Explanation:
*The code is in Python.
Ask the user to enter the weight and distance
Check the weight to calculate the weight_cost for 100 miles. If it is smaller than or equal to 2, set the weight_charge as 0.25. If it is greater than 2 and smaller than or equal to 10, set the weight_charge as 0.3. If it is greater than 10 and smaller than or equal to 20, set the weight_charge as 0.45. If it is greater than 20 and smaller than or equal to 50, set the weight_charge as 1.75
Since those charges are per 100 miles, you need to consider the distance to find the total_charge. If the int(distance / 100) is equal to (distance / 100), you set the d as int(distance / 100). Otherwise, you set the d as int(distance / 100) + 1. For example, if the distance is 400 miles, you need to multiply the weight_charge by 4, int(400/100) = 4. However, if the distance is 410, you get the int(400/100) = 4, and then add 1 to the d for the extra 10 miles.
Calculate the total_charge, multiply d by weight_charge
Print the total_charge

A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data according to internal instructions. A computer may be either digital, analog, or hybrid, although most in operation today are digital. Digital computers express variables as numbers, usually in the binary system. They are used for general purposes, whereas analog computers are built for specific tasks, typically scientific or technical. The term "computer" is usually synonymous with digital computer, and computers for business are exclusively digital.
The core, computing part of a computer is its central processing unit ( CPU), or processor. ... A computer system, therefore, is a computer combined with peripheral equipment and software so that it can perform desired functions.

Consider the following incomplete method, which is intended to return the longest string in the string array words. Assume that the array contains at least one element.
public static String longestWord(String[] words)
{
/* missing declaration and initialization */
for (int k = 1; k < words.length; k++)
{
if (words[k].length() > longest.length())
{
longest = words[k];
}
}
return longest;
}
Which of the following can replace /* missing declaration and initialization */ so that the method will work as intended?
a. int longest = 0;
b. int longest = words[0].length();
c. String longest = "";
d. String longest = words[0];
e. String longest = words[1];
Answer:
String longest = "";
Explanation:
The initialization that would allow the method to work as intended would be the following
String longest = "";
This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.

Answer:
An array.
Explanation:
An array can be defined as a structure that organizes data in a list that is commonly 1-dimensional or 2-dimensional.
Simply stated, an array refers to a set of memory locations (data structure) that comprises of a group of elements with each memory location sharing the same name. Therefore, the elements contained in array are all of the same data type e.g strings or integers.
Basically, in computer programming, arrays are typically used by software developers to organize data, in order to search or sort them.
Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements. Binary search applies the principles of divide and conquer.
In order to do a binary search on an array, the array must first be sorted in an ascending order.
Hence, array elements are mainly stored in contiguous memory locations on computer.

Explanation:
Design a program that generates a seven-digit lottery number. The program should generate seven random numbers, each in the range of 0 through 9, and assign each number to a list element. (Random numbers were discussed in Chapter 5 (Links to an external site.).) Then write another loop that displays the contents of the list
Answer:
In Python:
import random
lotterylist = []
for number in range(7):
lotterylist.append(random.randint(0,9))
for number in lotterylist:
print(number, end = ', ')
Explanation:
This line imports the random library
import random
This line creates an empty list
lotterylist = []
The instructions in this loop will be performed 7 times
for number in range(7):
This line generates a random number between 0 and 9 (inclusive) and then appends the number into lotterylist
lotterylist.append(random.randint(0,9))
This iterates through lotterylist
for number in lotterylist:
This prints the content of the list on a line (seperated by comma)
print(number, end = ', ')

Write a program to take in a time-of-day on the command-line as 3 integers representing hours, minutes, and seconds, along with a 4th argument of additional seconds. Recompute the time by adding the additional seconds to the time in the first three command-line arguments. Output: - display the original time given on the command-line - display the newly computed time Example: python computeTime.py 5 59 32 30 Initial time: 5:59:32 Computed time: 6:00:02 {6:0:2 would also be acceptable}
Answer:
In Python:
hh = int(input("Hour: ")) * 3600
mm = int(input("Minutes: ")) * 60
ss = int(input("Seconds: "))
seconds = int(input("Additional Seconds: "))
time = hh+ mm + ss + seconds
hh = int(time/3600)
time = time - hh * 3600
mm = int(time/60)
ss = time - mm * 60
while(hh>24):
hh = hh - 24
print(str(hh)+" : "+str(mm)+" : "+str(ss))
Explanation:
We start by getting the time of the day. This is done using the next three lines
hh = int(input("Hour: ")) * 3600
mm = int(input("Minutes: ")) * 60
ss = int(input("Seconds: "))
Then, we get the additional seconds
seconds = int(input("Additional Seconds: "))
The new time is then calculated (in seconds)
time = hh+ mm + ss + seconds
This line extracts the hours from the calculated time (in seconds)
hh = int(time/3600)
time = time - hh * 3600
This line extracts the minutes from the calculated time (in seconds)
mm = int(time/60)
This line gets the remaining seconds
ss = time - mm * 60
The following iteration ensures that the hour is less than 24
while(hh>24):
hh = hh - 24
This prints the calculated time
print(str(hh)+" : "+str(mm)+" : "+str(ss))
Write a program that prompts the user to enter a fraction in the following format (x/y). You may assume that the user will input numbers and a slash, but your program should deal with spaces. Use String methods to parse out the numerator and denominator (e.g. indexOf(), trim(), substring() etc.) Once you have the numerator and denominator, your program will determine whether the number is a proper fraction or an improper fraction. If it is a proper fraction, display the number. If not, reduce it to a mixed fraction or to an integer (see sample output below).
Answer:
fraction = input("enter fraction x/y: ")
if len(fraction) == 3:
if fraction[1] == "/":
try:
num = int(fraction[0])
den = int(fraction[2])
if num < den:
print(f"{num}/{den} is a proper fraction")
else:
if num% den == 0
print(f"{num}/{den} is an improper fraction and can be reduced to {num/den}")
else:
print(f"{num}/{den} is an improper fraction and can be reduced to {num//den} + {num - (den * (num//den))}/{den}")
except ValueError:
print("numerator and denominator must be integer numbers")
Explanation:
The try and except statement of the python program is used to catch value error of the input fraction of values that are not number digits. The program converts the numerator and denominator string values to integers and checks for the larger value of both.
The program prints the fraction as a proper fraction if the numerator is lesser and improper if not.
Team ordering You have the results of a completed round-robin tournament in which n teams played each other once. Each game ended either with a victory for one of the teams or with a tie. Design an algorithm that lists the teams in a sequence so that every team did not lose the game with the team listed immediately after it.What is the time efficiency class of your algorithm
Answer:
Following are the analogies to this question:
Explanation:
In each match, the group is a comparison because there may be a tie situation, which already implies, that its triage was unabated, 1 means the best team, and n means the worst team.
It makes it much easier to address whether another 'Quick Sort' or even the 'Merge Sort' issue by converting the very same problem throughout the number problem.
All the cases use for the Merge Sort, in which it utilizes its evenly divide or overcome strategy where the category is reciprocally divided into two parts where the number becomes measured at n==2, and the outcome extends.
Assume we get 7 squads:
2 4 5 4 3 1 6
Recursively split the above teams:
2 4 5 4 3 1 6
2 4 5 4 3 1 6
We'll equate such figures with base-case (n==2) (have a match against each other)
2 4 4 5 1 3 6 (number of matches 1(2,4) + 1(5,4) + 1(3,1) = 3)
Now the division is combined.
1, 2 ,3, 4, 4, 5
NLogN was its best time complexity of an algorithm but N is the lot of clubs.

1.21 LAB: Divide by x
Write a program using integers user_num and x as input, and output user_num divided by x three times.
Answer:
Explanation:
The following code is written in Python. It is a function called divide_by_x and takes the user inputs as described. It then raises x to the third power and divides user_num by that number. This gives the same result as user_num divided by x three times. The answer is saved in the variable answer which is then returned to the user.
def divide_by_x(user_num, x):
answer = user_num / (x**3)
return answer
The program is an illustration of the division arithmetic operation.
The program in Python, where comments are used to explain each line is as follows:
#This gets input for user_num
user_num = int(input())
#This gets input for x
x = int(input())
This loop is repeated three times
for i in range(1,4):
#This divides user_num by x, each time
user_num /= x
#This prints the required output
print(user_num)
At the end of the program, user_num is divided three times by x and then printed.

Define a class called UpdatedBook which inherits the BookInfo class created in Programming Project 3. This new class should contain an integer field for the edition number of the book, a constructor to create the UpdatedBook object accepting as input the author, title, and edition number of the book, and a getter method to return the edition number.
Answer:
Following are the class definition code to this question:
class UpdatedBook : BookInfo//defining a class UpdatedBook that inherits the BookInfo class
{
public:
int edition_Number;//defining an integer variable
UpdatedBook (string title,string author,int edition):BookInfo(b_title,b_author)//defining a constructor that
{
edition_Number=edition;
}
int getEdition_Number()
{
return edition_Number;
}
};
Explanation:
In this question, the "BookInfo" class is not defined, that's why we define this code as above.
In this code, a class "UpdatedBook" is defined that inherits its base class "BookInfo" inside the "UpdatedBook" class an integer variable "edition_Number" is declared, which is used to holding the integer value.
In the next step, a parameterized constructor is declared, that accepts a three-parameter and also inherits its base class parameterized constructor, and at the last, a get method is used that returns the edition number value.

(4 pts) Ex: Enter desired auto service: Oil change You entered: Oil change Cost of oil change: $35 The program should support the following services (all integers): Oil change -- $35 Tire rotation -- $19 Car wash -- $7 If the user enters a service that is not l
Answer:
In Python:
#1
service = input("Enter desired auto service: ")
print("You entered: "+service)
#2
if service.lower() == "oil change":
print("Cost of oil change: $35")
elif service.lower() == "car wash":
print("Cost of car wash: $7")
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
else:
print("Invalid Service")
Explanation:
First, we prompt the user for the auto service
service = input("Enter desired auto service: ")
Next, we print the service entered
print("You entered: "+service)
Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.
This is achieved using the following if conditions
For Oil Change
if service.lower() == "oil change":
print("Cost of oil change: $35")
For Car wash
elif service.lower() == "car wash":
print("Cost of car wash: $7")
For Tire rotation
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
Any service different from the above three, is invalid
else:
print("Invalid Service")

Which is true regarding how methods work? Group of answer choices If a method returns a variable, the method stores the variable's value until the method is called again A return address indicates the value returned by the method After a method returns, its local variables keep their values, which serve as their initial values the next time the method is called A method's local variables are discarded upon a method's return; each new call creates new local variables in memory
Answer:
A method's local variables are discarded upon a method's return; each new call creates new local variables in memory.
Explanation:
A local variable can be defined as an argument passed to a function or a variable that is declared within a function and as such can only be used or accessed within the function.
This ultimately implies that, a local variable is effective whilst the function or block is being executed (active).
Basically, all local variables can only be a member of either the register storage, static or auto (dynamic) categories in computer programming.
The true statement regarding how methods work is that a method's local variables are discarded upon a method's return; each new call creates new local variables in memory. This is so because these local variables are only allocated a storage that is within the frame of the method which is being executed on the run-time stack and would be discarded upon a method's completion or return.
Statement that is true regarding how methods work is :A method's local variables are discarded upon a method's return; each new call creates new local variables in memory.
A local variable serves as a variable which can be accessible within a particular part of a program.
These variables are usually defined within that routine and it is regarded as been local to a subroutine.
We can conclude that in method's local variables it is possible for each new call creates new local variables in memory.

developed the first compiler and conducted work that led to the development of COBOL ?
Answer:
Grace Hopper.
Explanation:
Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.
In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.
Additionally, the high-level programming language known as FLOW-MATIC that she invented in 1953 paved the way for the development of common business-oriented language (COBOL).
Hence, Grace Hopper developed the first compiler and conducted work that led to the development of COBOL.
Consider the following code segment. int[][] arr = {{3, 2, 1}, {4, 3, 5}}; for (int row = 0; row < arr.length; row++) { for (int col = 0; col < arr[row].length; col++) { if (col > 0) { if (arr[row][col] >= arr[row][col - 1]) { System.out.println("Condition one"); } } if (arr[row][col] % 2 == 0) { System.out.println("Condition two"); } } } As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
Answer:
Condition one - 1 time
Condition two - 2 times
Explanation:
Given
The above code segment
Required
Determine the number of times each print statement is executed
For condition one:
The if condition required to print the statement is: if (arr[row][col] >= arr[row][col - 1])
For the given data array, this condition is true only once, when
[tex]row = 1[/tex] and [tex]col = 2[/tex]
i.e.
if(arr[row][col] >= arr[row][col - 1])
=> arr[1][2] >= arr[1][2 - 1]
=> arr[1][2] >= arr[1][1]
=> 5 >= 3 ---- True
The statement is false for other elements of the array
Hence, Condition one is printed once
For condition two:
The if condition required to print the statement is: if (arr[row][col] % 2 == 0)
The condition checks if the array element is divisible by 2.
For the given data array, this condition is true only two times, when
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
i.e.
if (arr[row][col] % 2 == 0)
When [tex]row = 0[/tex] and [tex]col = 1[/tex]
=>arr[0][1] % 2 == 0
=>2 % 2 == 0 --- True
When [tex]row = 1[/tex] and [tex]col = 0[/tex]
=>arr[1][0] % 2 == 0
=> 4 % 2 == 0 --- True
The statement is false for other elements of the array
Hence, Condition two is printed twice

python program A year with 366 days is called a leap year. Leap years are necessary to keep the calendar in sync with the sun, because the earth revolves around the sun once very 365.25 days. As a result, years that are divisible by 4, like 1996, are leap years. However, years that are divisible by 100, like 1900, are not leap years. But years that are divisible by 400, like 2000, are leap years. Write a program named leap_year.py that asks the user for a year and computes whether that year is a leap year
Answer:
In Python:
year = int(input("Year: "))
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print("Leap year")
else:
print("Not a leap year")
else:
print("Leap year")
else:
print("Not a leap year")
Explanation:
This line prompts user for year
year = int(input("Year: "))
This condition checks if input year is divisible by 4
if (year % 4) == 0:
If yes, this condition checks if input year is divisible by 100
if (year % 100) == 0:
If yes, this condition checks if input year is divisible by 400
if (year % 400) == 0:
If divisible by 4, 100 and 400, then it is a leap year
print("Leap year")
else:
If divisible by 4 and 100 but not 400, then it is not a leap year
print("Not a leap year")
else:
If divisible by 4 but not 100, then it is a leap year
print("Leap year")
else:
If it is not divisible by, then it is not a leap year
print("Not a leap year")

myspeed = int(input("Enter user speed: "))
for mile in miles:
cal_time(mile, myspeed)
Explanation:
The python program prints out the time taken for a runner to cover the list of distances from 5 miles to a full marathon. The program prompts for the speed of the runner and calculates the time with the "cal_time" function.
