Writea SELECT statement that uses the ranking functions to rank products by the total quantity sold. Returnthese columns:The product_name column from the Products tableA column named total_quantity that shows the sum of the quantity for each product in theOrder_Items tableA column named rank that uses the RANK function to rank the total quantity in descending sequenceA column named dense_rank that uses the DENSE_RANK function to rank the total quantity in descending sequence
Answer:
SELECT product_name, SUM(DISTINCT quantity) AS total_quantity
RANK() OVER (PARTITION BY total_quantity ORDER BY product_name) AS rank,
DENSE_RANK () OVER (ORDER BY quantity DESC) AS dense_rank
FROM Order_items
JOIN products ON Order_items.product_id = products.product_id
GROUP BY product_id
Explanation:
The SQL query returns four columns namely, product name, total quantity, rank and dense rank. The query uses the rank and the dense rank function to return the rows according to numeric ranks.

Write a program with a method called passwordCheck to return if the string is a valid password. The method should have the signature shown in the starter code.
The password must be at least 8 characters long and may only consist of letters and digits. To pass the autograder, you will need to print the boolean return value from the passwordCheck method.
Hint: Consider creating a String that contains all the letters in the alphabet and a String that contains all digits. If the password has a character that isn’t in one of those Strings, then it’s an illegitimate password!
Coding portion:
public class Password
{
public static void main(String[] args)
{
// Prompt the user to enter their password and pass their string
// to the passwordCheck method to determine if it is valid.
}
public static boolean passwordCheck(String password)
{
// Create this method so that it checks to see that the password
// is at least 8 characters long and only contains letters
// and numbers.
}
}
Answer:
import java.util.regex.*;
import java.util.Scanner;
public class Password
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Please enter the Password. \n");
String passwordString = input.next();
System.out.println(passwordCheck(passwordString));
}
public static boolean passwordCheck(String password){
if(password.length()>=8 && password.matches("[a-z0-9A-Z]+")){
return true;
}
else{
return false;
}
}
}
Explanation:
The Java class "Password" is used by the program to make an instance of the password object and check its validity with the passwordChecker method defined within the Password class. The passwordChecker method only matches alphanumeric passwords, that is, passwords with alphabets and numbers. If a non-alphanumeric character is encountered, the boolean value false is returned.

Explanation:
Write a program that reads a stream of integers from a file and prints to the screen the range of integers in the file (i.e. [lowest, highest]). You should first prompt the user to provide the file name. You should then read all the integers from the file, keeping track of the lowest and highest values seen in the entire file, and only print out the range of values after the entire file has been read.
Answer:
This question is answered using C++ programming language
#include <fstream>
#include<iostream>
using namespace std;
int main() {
string fname;
cout<<"Enter Filename: ";
cin>>fname;
int lowest = 0;
int highest = 0;
ifstream ifs(fname);
int x;
while (ifs >> x){
if(x < lowest){
lowest= x;
}
if(x > highest) {
highest = x;
}
}
ifs.close();
for(int i = lowest; i<=highest;i++)
{
cout<<i<<" ";
}
}
Explanation:
This line declares fname as string
string fname;
This prompts user for filename
cout<<"Enter Filename: ";
This gets filename
cin>>fname;
This declares and initializes lowest to 0
int lowest = 0;
This declares and initializes highest to 0
int highest = 0;
This defines the file using ifstream
ifstream ifs(fname+".txt");
This declares x as integer. x is used to read integers in the file
int x;
The following iteration will be repeated until there is no other integer to be read from the file
while (ifs >> x){
This checks for lowest
if(x < lowest){
lowest= x;
}
This checks for highest
if(x > highest) {
highest = x;
}
}
This closes the file. i.e. the file has been read
ifs.close();
The following iteration prints the range of values from lowest to highest
for(int i = lowest; i<=highest;i++) {
cout<<i<<" ";
}
Please note that the filename must be entered with its extension

Explanation:
Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings
Sample game board at the arcade GAME COMPLETION TIME (in minutes) PAYOUT RATE Pac-man 90 400 Mortal Kombat 10 30 Super Tetris 25 100 Pump it Up 10 40 Street Fighter II 90 450 Speed Racer 10 40
An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.
Question:
Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money?.
Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?
Input Explanation
The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
The games board may change but the store still closes in 120 minutes.
Input
6
Pac-man,80,400
Mortal Kombat,10,30
Super Tetris,25,100
Pump it Up,10,40
Street Fighter II,90,450
Speed Racer,10,40
Output Explanation
Print the game names that earn him the most into the standard output in alphabetical order
Output
Mortal Kombat
Pump it Up
Speed Racer
Street Fighter II

The Boolean operators include which of the following?
A. and, or, not
B. to, for, from
C. a, an, the
D. is, are, not
Answer:
The answer is A. and, or, not
Explanation:
Using a Boolean search can help narrow your results. A Boolean search is a query that uses the Boolean operators AND, OR, and NOT, along with quotation marks, to limit the number of results. For example, searching the terms Alexander the Great AND conquests will provide results about Alexander, great, and their conquests.

Explanation:
Consider the following Java program. Describe what it does in response to specific operations of the mouse, and how it does it. (You are encouraged to run the program for yourself to test its behavior. Then read through the program carefully to understand how that behavior arises.)
import java.awt.event.*;
import javax.swing.*;
public class MouseWhisperer extends JFrame implements MouseListener {
MouseWhisperer() {
super("COME CLOSER");
setSize(300,100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
addMouseListener(this);
setVisible(true);
}
public void mouseClicked(MouseEvent e) { setTitle("OUCH"); }
public void mousePressed(MouseEvent e) { setTitle("LET GO"); }
public void mouseReleased(MouseEvent e) { setTitle("WHEW"); }
public void mouseEntered(MouseEvent e) { setTitle("I SEE YOU"); }
public void mouseExited(MouseEvent e) { setTitle("COME CLOSER"); }
public static void main(String[] args) { new MouseWhisperer(); }
}
Answer:
Explanation:
This java code creates a windowed java application that is 300x100 pixels large. The title of the program which is located in the bar at the top of the program starts off by saying "Come Closer". If you move the mouse over the program the program detects it. Then if you press the program it changes the title to "Let Go". If you press the program and immediately let go it changes the title to "Ouch" but if you hold for 1 or 2 seconds and let go it changes the title to "Whew". Finally, if you move the mouse cursor away from the program it changes the title back to "Come Closer"
Course Aggregation Many times, departments are only interested with how students have done in courses relative to a specific major when considering applicants for admission purposes.
For this problem you are given a dictionary where the keys are strings representing student ids and the values are dictionaries where the keys represent a course code and the value represents a grade. Your task is to write a function that given a dictionary of the described format and a prefix for course codes, return a dictionary where each key is a student id and the corresponding value is the average grade of the student only in courses that start with the given prefix.
def course_grader (student_to_grades, course_prefix): ({str, {str, float}}) -> {str, float} I: a dictionary containing the grades of students (as described above) and a course code prefix P: compute and store the average grade of all students only for courses that start with the given course prefix 0: a dictionary of student ids to average grades as described in the Processing step pass
Answer:
def course_grader(student_to_grades, course_prefix):
student_grades = dict()
for key, value in student_to_grades.items():
grade_score = 0
for course,grade in value.items():
if course_prefix == course:
grade_score += grade
student_grades[key] = grade_score / len(value.keys())
return student_grades
Explanation:
The course_grader function is a python program that accepts two arguments, the student dictionary and the course prefix. The function returns a dictionary of the student id as the key and the average grade of the student as the value.
One of the following is NOT a basic linked list operation:_________.
a) search
b) insert
c) create
d) delete
e) traverse
f) destroy
g) build list from file
Answer:
One of the following is NOT a basic linked list operation:_________.
g) build list from file
Explanation:
Linked list operation is the creation of trees and graphs or a chain of data elements, which are called nodes. Each note points to the next using a pointer. In linked lists, each node consists of its own data and the address of the next node. A linked list, which may be single, double, or circular, forms a chain-like structure that builds from one node to the other.

In python, Write a function (name: identi Substring) that, given a string S, returns an integer that represents the numbers of ways in which we can select a non-empty substring of S where all of the characters of the substring are identical. Two substrings with the same letters but different in locations are still considered different. For example, the string "zzzyz" contains 8 such substrings. Four instances of "z", two of "zz", one of "zzz" and one instance of "y". String "k" contains only one such substring:"k". The length of S will be between 1 and 100, inclusive. Each character in S will be a lowercase letter (a-z).
Answer:
def identiSubstring(S):
n = len(S)
inst = ""
count= 0
for Len in range(1,n+1):
for i in range(n-Len+1):
for k in range(i,i + Len):
inst =inst+S[k]
if(len(set(inst)) == 1):
count = count + 1
inst = ""
return count
S = input("Enter a string: ")
if(len(S)>=1 and len(S)<=100):
print("There are "+str(identiSubstring(S.lower()))+" possible occurrences")
else:
print("Length is invalid")
Explanation:
This line defines the required function
def identiSubstring(S):
This calculates the length of string S
n = len(S)
This initializes an instance of the required string to an empty string
inst = ""
This initializes count to 0
count= 0
This following iterations iterate through the length of the string
for Len in range(1,n+1):
for i in range(n-Len+1):
for k in range(i,i + Len):
This gets an instance of string S
inst =inst+S[k]
This checks if the characters of the instance are identical
if(len(set(inst)) == 1):
If yes, the counter is incremented by 1
count = count + 1
This instance is reset back to an empty string
inst = ""
This returns the number of instances of the substring
return count
The main begins here
This prompt user for a string
S = input("Enter a string: ")
This checks for valid length
if(len(S)>=1 and len(S)<=100):
If length is between 1 and 100 (inclusive), this calls the identiSubstring function
print("There are "+str(identiSubstring(S.lower()))+" possible occurrences")
If otherwise
else:
This prints invalid length
print("Length is invalid")

Write a program that reads in at most 100 integers that are between 1 and 100 and counts the occurrence of each number in the list. Assume the list ends when a zero is inputted.
Answer:
#include <iostream>
#include <map>
using namespace std;
int main()
{
map<int, int> numbers;
cout << "Enter numbers, 0 to finish" << endl;
int number;
while (true) {
cin >> number;
if (number == 0) break;
numbers[number]++;
}
for (pair<int, int> element : numbers) {
std::cout << element.first << ": occurs " << element.second << " times" << std::endl;
}
}
Explanation:
One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.

what type of collection is used in the assignment statement
info: [3:10,4:23,7:10,11:31]
tuple
list
Duque
dictionary
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
There are four data types in Python used to store data such as tuple, list, set, and dictionary.
The correct answer to this question is option D: Dictionary
Dictionary data type is used to store data values in key:value pairs as given in the question. It is a collection that is changeable, unordered, and does not allow duplicate entries.
Dictionaries in Python are written with curly brackets and have keys and values such as car={name="honda", model=2010}
when you run the given assignment statment such
info= {3:10,4:23,7:10,11:31}
print(info)
It will print the info dictionary (key:value pair)
{3: 10, 4: 23, 7: 10, 11: 31}
While other options are not correct because:
Tuples in Python are used to store multiple items in a single variable. For example:
info=("apple", "banana", "cherry")
List is used to store multiple items in a single variable. for example
myList = ["apple", "banana", "cherry"]
print(myList)
The list is ordered, changeable, and allows duplicate entry. But you can not put key: value pair in the list.

g Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.Create a Java program Ex: If the input is: 8 5 2 3 4 10 6 8 9
Answer:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int arraylent;
Scanner input = new Scanner(System.in);
System.out.print("Array Length: ");
arraylent= input.nextInt();
int[] myarray = new int[arraylent];
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
}
}
Explanation:
This declares the length of the array
int arraylent;
This next two lines prompt and get the array length i.e. number of input
System.out.print("Array Length: ");
arraylent= input.nextInt();
This declares the array as type integer. And the length of the array is gotten from the user input
int[] myarray = new int[arraylent];
This gets the items of the array
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
This reverse and prints the array
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
