Write a program in python to calculate the amount each person must pay toward the bill and toward the tip, for a group of friends who are eating out together. Since you are all friends, it is okay to split the costs evenly.

Your program should take as input:

1. The restaurant bill (without tax or tip) as a floating point number
2. The sales tax rate as a floating point number (for example: an 8% tax rate would be 0.08)
3. The level of service as an integer between 0 and 10
   0 is terrible (0% tip), 5 is average (15% tip), and 10 is excellent (30% tip)
4. The number of friends to split the check among

Your program should output:

1. The amount each friend should pay toward the bill (with tax)
2. The amount each friend should leave in tip
   tip should be calculated on the pre-tax restaurant bill
3. The total amount each diner should pay, including restaurant bill, sales tax, and tip
4. The overall total, which includes the restaurant bill, the sales tax, and the tip

For example, with the following inputs:

Restaurant bill (without tax or tip): $35
Sales tax rate: 0.08
Level of service: 7
Number of friends: 3

the output should be:

Bill per person with tax: $12.6
Tip per person: $2.4499999999999997
Total per person: $15.049999999999999
Total bill including tax and tip: $45.15 

Note that because floating point values often incur rounding errors, the output might not be completely accurate. This will not affect the grading. However, please make your input and output look like the example above, so that the automated system can evaluate your results.

Things to think about when you’re writing these programs:

1. Follow the recipe: collect all your input first; then calculate the required results; then output the results.
2. Spend some time choosing your variable names carefully. Names should be descriptive.
3. Take advantage of variables to name values whose purpose may not be obvious.
4. Take advantage of variables by breaking any complex expressions down into a set of simpler expressions and storing the intermediate results in variables

This is an intro to Java Question. My current solution is giving me bad outputs. Please show me your way of solving this.

Problem 4: Min/Max Search by Value Develop a program that, given a sequence S of integers as input, produces as two output values, the first is the minimum value that appears in the sequence and the second is the maximum value that appears in the sequence.

Facts

● Scanner has a method that returns a boolean indicating whether a next integer exists in its input stream ( hasNextInt() )

● Scanner objects can be initialized to to scan String data as input.

Input

The input will begin with a single line containing T , the number of test cases to follow. The remaining lines contain the T sequences, one line per sequence. Each of these lines contains the values in the sequence. Each such value is separated from the next by at least one space.

Output For each sequence given as input, there should be four lines of output. The first line echos the given sequence. The second line indicates the minimum value that occurs. The third line indicates the maximum value that occurs. The fourth line is blank.

Sample Input

3

3 6 -1 4 6 5 3

0 0 0 0 -4 45 2 0 3 5 11 -7 854 25 3 -7 4 -3

Sample Output 3 6 -1 4 6 5 3

-1

0 0 0 0

-4 45 2 0 3 5 11 -7 854 25 3 -7 4 -3

-7

854

So Far This is what I have:

import java.util.Scanner;

public class MinMaxSearchByValue {

   public static void main(String [] args) {

       Scanner input = new Scanner(System.in);

       int cases = input.nextInt();

       input.nextLine();

       for (int i = 0; i < cases; i++) {

           String givenListOfNums = input.nextLine();

           Scanner stringScanner = new Scanner (givenListOfNums);

           int min = stringScanner.nextint();

           int max = min;

           while (stringScanner.hasNextInt()) {

               int nextValue = stringScanner.nextInt();

               if(nextValue < min) {

                   min = nextValue;}

                   else if (nextValue > max) {
                      
                       max = nextValue;
                   }
           }
       }

System.out.printf("%s%n%d%n%d%n%n", givenListOfNums, min, max);

   }

}

I have defined the class. Rectangle in Python. How do I define a class Canvas with the following description:

Class Canvas represents a collection of Rectangles. It has 8 methods. In addition, to the constructor
(i.e. __init__ method) and two methods that override python's object methods (and make your class
user friendly as suggested by the test cases), your class should contain 5 more methods:
add_one_rectangle, count_same_color, total_perimeter, min_enclosing_rectangle, and common_point.

In programming, we are always assigning one variable to another. With the use of primitive data types that is not a problem. With classes, the program needs to know how to do the assignment. Explain the concepts of deep copy and member wise assignment.

Write a factorial C++ program where n=10,000,000

Write a class file called lastname_digits.java. In it, write a method to compute and return the total instances where the sum of digits of the array equals to the target.

Write a demo file called lastname_digits_demo.java. Create an array of random 10 integers between 301 and 999. Also create an integer variable called target that is equal to a value between 5 and 10. Print the answer within this file.

Example:

If five of the 20 integers are equal to 512, 607, 620, 767, 791 and the target is 8. Sum of the four integers is equal to 5+1+2 = 8, 13, 8, 20, 17. Then the total instances where the sum of digits of the array equals to the target is equal to 2.

Write a “C” program(Linux) that creates a pipe and forks a child process. The parent then sends the following message on his side of the pipe “I am your daddy! and my name is <pid-of the-parent-process>\n”, the child receives this message and prints it to its stdout verbatim. The parent then blocks reading on the pipe from the child. The child writes back to its parent through its side ofthe pipe stating “Daddy, my name is <pid-of-the-child>”. The parent then writes the message received from the child to its stdout. Make sure the parent waits on the child exit as to not creating orphans or zombies. Include Makefile.
