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:

def cal_time(distance, speed):

   time = distance / speed

   hour = str(time)[0]

   minutes = round(float(str(time)[1:]) * 60)

   print(f"The time taken to cover {distance}miles is {hour}hours, {minutes}minutes")

miles = [5, 10, 13.1, 26.2]

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.

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.

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.

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.

Answer:

The program in Python is as follows:

import random

secretNum = random.randint(1,10)

userNum = int(input("Take a guess: "))

while(userNum != secretNum):

    print("Incorrect Guess")

    userNum = int(input("Take a guess: "))

print("You guessed right")

Explanation:

This imports the random module

import random

This generates a secrete number

secretNum = random.randint(1,10)

This prompts the user to take a guess

userNum = int(input("Take a guess: "))

This loop is repeated until the user guess right

while(userNum != secretNum):

    print("Incorrect Guess")

    userNum = int(input("Take a guess: "))

This is executed when the user guesses right

print("You guessed right")

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

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.

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.

Answer:

Explanation:

The following code is written in Python. It creates the function called sum_of_ends and does exactly as the question asks, it sums the first and last elements of the array and returns it to the user, if the array is empty it will return 0.

def sum_of_ends(num_arr):

   if len(num_arr) == 0:

       return 0

   else:

       sum = num_arr[0] + num_arr[-1]

       return sum

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")

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.

Answer: the top 3 are Microsoft word

                                     Microsoft Excel

                                     Microsoft PowerPoint

Explanation:

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))

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.

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

   list_length = len(list_values)

   try:

       #loop it up

       for i in range(list_length):

           list_values[i] = float(list_values[i])

       #Add up all the numbers, put into list_sum

       List_sum = sum(list_values)

       #heres how we average it

       Average_value = (List_sum)/list_length

Explanation:

The python program uses the try-except exception handling method to catch errors in the code. The IOError is used for catching input and output errors in the program like file handling while the ValueError keyword in the except statement is used to catch data type errors from a return statement, calculation or user input.
