Asks a user to enter n values, then calculates and returns
the minimum, maximum, total, and average of those values.
Use: minimum, maximum, total, average = statistics(n)
-------------------------------------------------------
Parameters:
n - number of values to process (int > 0)
Returns:
minimum - smallest of n values (float)
maximum - largest of n values (float)
total - total of n values (float)
average - average of n values (float)

Create a program that determines the name of the person with the highest or lowest number of votes. The data will be in two arrays. The first array is of type String and has the following names in it: Mike Muldune Justin Meiber Clark Kent Ana Karina The second array is of type integer and has the following numbers in it: 2324, 2425, 3344 and 2526. Ask the user to enter a 1 for highest and 2 for lowest. If the user enters a 1, print the name of the person with the highest number of votes and the number of votes received. It the user enters a 2, print the name of the person with the lowest number of votes and the number of votes received.

Write the following questions as queries in Relational Algebra. Use only the operators discussed in class (select, project, Cartesian product, join, union, intersection, set difference and renaming —in particular, no outer joins or aggregations). Type your answers. If you can’t find Greek letters in your word processor, you can simply write out the operator, all uppercase (i.e. ’SELECT’). Please use renaming consistently, as indicated in the handout. Before starting, make sure you understand the schema of the database. If you are in doubt about it, please ask the instructor.

Assume a database with schema:

ACTOR(name,age,address,nationality)

MOVIE(title,year,genre,budget,director-name,studio)

APPEARS(name,title,salary)

Write the following questions in Relational Algebra:

1. List the titles and budgets of movies where actor Keanu Reeves appeared in 1999.

2. List the names and ages of actors who have appeared in a comedy produced by Studio ’MGM’.

3. List the names of directors who have directed a drama or a comedy.

4. List the names of directors who have directed a drama and a comedy.

5. List pairs of actors who have appeared together in a movie (note: the schema of your answer should be (name1,name2), where both name1 and name2 are names of actors.

For example

My IP address 128. 0. 0. 1

My IP address 53. 20. 62. 201

My IP address 77. 122. 180. 76

My IP address 54. 33. 11. 11

My IP address 33. 33. 2. 11

My IP address 202. 29. 205. 69

My IP address 215. 18. 15. 185

My IP address 56. 66. 33. 30

How do you write a regular expression that covers all IP addresses and display all list using a loop in Python

Write the method: public static String removeSubstring(String s1, String s2) Method removeSubstring(String s1, String s2)

Must do 3 things:
1. Take two parameters, the original String (String s1) and the substring (String s2) that is to be removed;
2. Create a new String that consists of the original String data less all occurrences of the substring data;
3. Return the new String.

Note:
1. The data to be removed is each occurrence of the complete substring, not individual characters of the substring. For example, if the original String is “hello” and the substring is “el”, the String to be returned is “hlo” and not “ho”.
2. The second, third and fourth examples include spaces, so the substring also includes a space that is to be removed.

PLEASE HELP ME UNDERSTAND HOW TO COMPLETE THIS CODE BELOW:

public class RemoveSubstring
{
   public static void main(String [] args)
   {

   String testString1 = "173167176531317";
   String subStr1 = "17";
  
   String testString2 = "I am not happy";
   String subStr2 = "not ";
  
   String testString3 = "I am not happy and not glad";
   String subStr3 = "not ";
  
   String testString4 = "neither this nor that works!";
   String subStr4 = "neither this nor ";
  
   System.out.println("The string " + testString1 + " without " + subStr1 + " is: " + removeSubstring(testString1, subStr1));
   System.out.println("The string " + testString2 + " without " + subStr2 + " is: " + removeSubstring(testString2, subStr2));
   System.out.println("The string " + testString3 + " without " + subStr3 + " is: " + removeSubstring(testString3, subStr3));
   System.out.println("The string " + testString4 + " without " + subStr4 + " is: " + removeSubstring(testString4, subStr4));

   }

   public static String removeSubstring(String s1, String s2)
   {
  
return("PLEASE HELP ME UNDERSTAND HOW THIS WORKS OR WHERE TO LEARN MORE I AM LOST HERE THANK YOU");
   }

Copy the following Python fuction discussed in class into your file:

from random import *
def makeRandomList(size, bound):
    a = []
    for i in range(size):
        a.append(randint(0, bound))
    return a

a. Add another function that receives a list as a parameter and computes the sum of the elements of the list. The header of the function should be

def sumList(a):

The function should return the result and not print it. If the list is empty, the function should return 0. Use a for loop iterating over the list.

Test the function in the console to see if it works.

b. Write a function that receives a list as a parameter and a value, and returns True if the value can be found in the list, and Falseif not. Use a for loop that goes over the list and compares each element to the value. If any of them is equal to the value, it returns True. Otherwise after the loop is done, you can return False. Thus, if the loop completes without a return statement happening, then the value is not in the list. The function header should look like this:

def searchList(a, val):

Test this second function a few times the same way as the first one.

c. Below the three functions, add a piece of code that

• calls the function makeRandomList to generate a list with a size of 10 and a bound of 50, stores it in a variable, and prints it.
• Then it should call the function sumList to compute the sum and also print the result.
• Finally, it should ask the user for a value, input it and store it in a variable, then call the function searchList with the list and this variable, and output the result.

Test the program to make sure that it works fine.
