Write a program named BinaryToDecimal.java that reads a 4-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is 1100, the output should be 12. (Hint: break the string into substrings and then convert each substring to a value for a single bit. If the bits are b0, b1, b2, b3, then decimal equivalent is 8b0 4b1 2b2 b3)
Answer:
import java.util.*;
public class BinaryToDecimal
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String binaryNumber;
int decimalNumber = 0;
System.out.print("Enter the binary number: ");
binaryNumber = input.nextLine();
for(int i=0; i<binaryNumber.length(); i++){
char c = binaryNumber.charAt(binaryNumber.length()-1-i);
int digit = Character.getNumericValue(c);
decimalNumber += (digit * Math.pow(2, i));
}
System.out.println(decimalNumber);
}
}
Explanation:
Create a Scanner object to be able to get input from the user
Declare the variables
Ask the user to enter the binaryNumber as a String
Create a for loop that iterates through the binaryNumber. Get each character using charAt() method. Convert that character to an integer value using Character.getNumericValue(). Add the multiplication of integer value and 2 to the power of i to the decimalNumber variable (cumulative sum)
When the loop is done, print the decimalNumber variable

Explanation:
Write a program that accepts two numbers R and H, from Command Argument List (feed to the main method). R is the radius of the well casing in inches and H is the depth of the well in feet (assume water will fill this entire depth). The program should output the number of gallons stored in the well casing. For your reference: The volume of a cylinder is pi;r2h, where r is the radius and h is the height. 1 cubic foot
Answer:
Answered below.
Explanation:
#Answer is written in Python programming language
#Get inputs
radius = float(input("Enter radius in inches: "))
height = float(input("Enter height in feet: "))
#Convert height in feet to height in inches
height_in_inches = height * 12
#calculate volume in cubic inches
volume = 3.14 * (radius**2) * height_to_inches
#convert volume in cubic inches to volume in gallons
volume_in_gallons = volume * 0.00433
#output result
print (volume_in_gallons)

The first and second numbers in the Fibonacci sequence are both 1. After that, each subsequent number is the sum of the two preceding numbers. The first several numbers in the sequence are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc. Write a function named fib that takes a positive integer parameter and returns the number at that position of the Fibonacci sequence. For example fib(1)
Answer:
In Python:
def fib(nterms):
n1, n2 = 1, 1
count = 0
while count < nterms:
term = n1
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
return term
Explanation:
This line defines the function
def fib(nterms):
This line initializes the first and second terms to 1
n1, n2 = 1, 1
This line initializes the Fibonacci count to 0
count = 0
The following while loops gets the number at the position of nterms
while count < nterms:
term = n1
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
This returns the Fibonnaci term
return term

Explanation:
The necessary code to accomplish the task is written in bold face. It contains comments explaining important parts of the code.
magine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum. For this application, the cost of inserting is not important, because itcan be done off-line prior to startup of the time-critical section, but the performance of the two deletionoperations are critical. Repeated deletions of either kind must work as fast as possible. Suggest a datastructure that can support this application, and justify your suggestion. What is the time complexity foreach of the three key operations
Answer:
Use the stack data structure with both best-case and worst-case time complexity of O(1) for insertion and deletion of elements.
Explanation:
The stack data structure is used in programs to hold data for which the last data in the stack is always popped out first when retrieving the data sequentially, that it, first-in, last-out.
The elements in the stack are located in an index location, which means that they can be retrieved directly by choice with constant time complexity of 1 or O(1) for best and worst-case.
So inserting, and deleting the minimum and maximum elements in the stack data structure executes at a speed of the constant 1 (big-O notation, O(1) ).
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:
Follows are the code to this question:
y = int(input("Enter a year: "))#input year value
if((y%4==0) and (y%100==0) or y%400==0):#defining if block for check leap year condition
print("Given year {0}, is a leap year".format(y))#print value
else:#else block
print("Given year {0}, is not a leap year".format(y))#print value
Output:
Enter a year: 1989
Given year 1989, is not a leap year
Explanation:
In the python code, the y variable uses the input method for input the value from the user-end. In the next step, if a conditional block is used, that's checks the leap-year condition. if the condition is true it will print leap year value with the message, otherwise, it will go to else block that prints not a leap year message.

Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In
this case, the country that produces rye will produce million bushels per week, and the country that produces jeans will produce
million pairs per week.
Answer:
In this case, the country that produces rye will produce 24 million bushels per week, and the country that produces jeans will produce 64 million pairs per week.
Explanation:
Total labor hour = 4 million hour
Number of bushes produce in 1 hour = 6
⇒total bushes produce = 6*4 = 24 million
∴ we get
The country that produces rye will produce 24 million bushels per week
Now,
Total labor hour = 4 million hour
Number of pairs produce in 1 hour = 16
⇒total bushes produce = 16*4 = 64 million
∴ we get
The country that produces jeans will produce 64 million pairs per week.

g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.
Answer:
In Python:
loop = True
while(loop):
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
result = nm2 * nm3 + nm1
print("Result: "+str(result))
loop = True
else:
print("All inputs must be greater than or equal to 0")
loop = True
Explanation:
First, we set the loop to True (a boolean variable)
loop = True
This while loop iterates, indefinitely
while(loop):
The next three lines prompt user for three numbers
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
The following if condition checks if all of the numbers are greater than or equal to 0
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
If yes, the result is calculated
result = nm2 * nm3 + nm1
... and printed
print("Result: "+str(result))
The loop is then set to true
loop = True
else:
If otherwise, the user is prompted to enter valid inputs
print("All inputs must be greater than or equal to 0")
The loop is then set to true
loop = True
In Cloud9, create a new file called function.cpp. If you aren't sure how to create a new .cpp file in the Cloud9 environment, refer Slide 24 of the Cloud9SetUpSlides (Links to an external site.). In this new file write a function called swapInts that swaps (interchanges) the values of two integers that it is given access to via pointer parameters. Write a main function that asks the user for two integer values, stores them in variables num1 and num2, calls the swap function to swap the values of num1
Answer:
#include <iostream>
using namespace std;
void swapInts(int* x, int* y) {
*x = *x + *y;
*y= *x - *y;
*x = *x - *y;
}
int main(){
int num1, num2;
cout << "Before swap:";
cin>>num1; cin>>num2;
swapInts(&num1, &num2);
cout<<"After swap:"<<num1<<" "<<num2;
}
Explanation:
The function begins here:
This line defines the function
void swapInts(int* x, int* y) {
The next three line swap the integer values
*x = *x + *y;
*y= *x - *y;
*x = *x - *y;
}
The main begins here:
int main(){
This line declares two integer variables
int num1, num2;
This line prompts the user for inputs before swap
cout << "Before swap:";
This line gets user inputs for both integers
cin>>num1; cin>>num2;
This line calls the function
swapInts(&num1, &num2);
This prints the numbers after swap
cout<<"After swap:"<<num1<<" "<<num2;
}

Write a program that rolls two dice until the user gets snake eyes. You should use a loop and a half to do this. Each round you should roll two dice (Hint: use the randint function!), and print out their values. If the values on both dice are 1, then it is called snake eyes, and you should break out of the loop. You should also use a variable to keep track of how many rolls it takes to get snake eyes.
Sample Run:
Rolled: 6 5
Rolled: 5 2
Rolled: 3 6
Rolled: 6 2
Rolled: 1 2
Rolled: 5 3
Rolled: 1 4
Rolled: 1 1
It took you 8 rolls to get snake eyes.
I have most of the code but when it prints it say you rolled 0 times every time.
import random
# Enter your code here
num_rolls = 0
import random
# Enter your code here
while True:
roll_one = random.randint(1,6)
roll_two = random.randint(1,6)
print ("Rolled: " +str(roll_one) +"," + str(roll_two))
if (roll_one == 1 and roll_two == 1):
print ("it took you " + str(num_rolls) + " rolls")
break
output:
Rolled: 3,5
Rolled: 6,4
Rolled: 2,4
Rolled: 3,6
Rolled: 5,2
Rolled: 1,1
it took you 0 rolls
suppose to say:
It took you (however many rolls) not 0
import random
num_rolls = 0
while True:
r1 = random.randint(1, 6)
r2 = random.randint(1, 6)
print("Rolled: " + str(r1) + "," + str(r2))
num_rolls += 1
if r1 == r2 == 1:
break
print("It took you "+str(num_rolls)+" rolls")
I added the working code. You don't appear to be adding to num_rolls at all. I wrote my code in python 3.8. I hope this helps.
The program uses loops and conditional statements.
Loops perform repetitive operations, while conditional statements are statements used to make decisions
The program in Python where comments are used to explain each line is as follows:
#This imports the random module
import random
#This initializes the number of rolls to 0
num_rolls = 0
#The following loop is repeated until both rolls are 1
while True:
#This simulates roll 1
roll_one = random.randint(1,6)
#This simulates roll 2
roll_two = random.randint(1,6)
#This prints the outcome of each roll
print ("Rolled: " +str(roll_one) +"," + str(roll_two))
#This counts the number of rolls
num_rolls+=1
#When both rolls are the 1
if (roll_one == 1 and roll_two == 1):
#This exits the loop
break
#This prints the number of rolls
print ("it took you " + str(num_rolls) + " rolls")
