Early Middle Ages
O Late Middle Ages
O High Middle Ages
O New Middle Ages
allowing is NOT an artifact of the Information Age?
The one that is not a period of the Middle Ages is the High Middle Ages. The correct option is c.
What are different ages?The Middle Ages, which roughly correspond to the years 500 to 1400–1500 BCE, is the term used to describe this time of European history. The phrase was initially used by academics in the 15th century to refer to the time frame between their own era and the dissolution of the Western Roman Empire.
The period between the fall of Imperial Rome and the start of Early Modern Europe is referred to as the “Middle Ages” for this reason. The reason the Middle Ages are known as the Dark Ages is that life was hard and brief in Europe, and contrasted with the orderliness of classical antiquity.
The time period in European history from roughly 500 AD to 1500 AD. This time period's early years are commonly referred to as the Dark Ages.
Therefore, the correct option is c, High Middle Ages.

Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0.
Answer:
import random
decisions = int(input("How many decisions: "))
for i in range(decisions):
number = random.randint(0, 1)
if number == 0:
print("heads")
else:
print("tails")
Explanation:
*The code is in Python.
import the random to be able to generate random numbers
Ask the user to enter the number of decisions
Create a for loop that iterates number of decisions times. For each round; generate a number between 0 and 1 using the randint() method. Check the number. If it is equal to 0, print "heads". Otherwise, print "tails"
Create an interface called Runner. The interface has an abstract method called run() that displays a message describing the meaning of run to the class. Create classes called Machine, Athlete, and PoliticalCandidate that all implement Runner.
The run() should print the following in each class:
Machine - When a machine is running, it is operating.
Athlete - An athlete might run in a race, or in a game like soccer.
PoliticalCandidate - A political candidate runs for office.

Explain why you have to import JOptionPane but not the Math class
Answer:
To provide standard dialog boxes such as message dialog box, confirm dialog box and input dialog box.
In Java, the import statement is used to include classes or packages from outside sources in your code. This lets you access and use the features of those classes or packages.
What is the JOptionPaneTo do the above, You need to import JOptionPane in Java because it belongs to a different package from the Math class.
The Math class is a part of the java. lang package, which is automatically included in Java. This package has important classes and interfaces that are used in Java programs. Because the Math class is already included in this package, you don't have to import it separately.

A. 1
B. 2
C. 3
D. 4
Answer: C
Explanation: Computing Device A is connected using 3 wires, which all lead to multiple different paths of wires. If you break all the wires off of A, it leaves it with no paths to use. However, if you do this with E, there is 4 differents paths connected to it. Since you need the MINIMUM, the answer would be C.
Which of the following is true of how packets are sent through the internet?
Answer:
It is A: Packet metadata is used to route and reassemble information travelling through the internet.
Explanation:
Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee
Step 2: Entering the network
Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.
Step 3: Taking flight
The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.
Step 4: BGP
These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.
Step 5: Finding a route
This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.
Step 6: Bad information
For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.
Last step: Arrival
The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.
Write the three working fundamental steps of a computer.
Answer:
just tryin' to help you
Explanation:
The three stages of computing are input, processing and output. A computer works through these stages by 'running' a program. A program is a set of step-by-step instructions which tells the computer exactly what to do with input in order to produce the required output.
Using the Multiple-Alternative IFTHENELSE Control structure write the pseudocode to solve the following problem to prepare a contract labor report for heavy equipment operators: The input will contain the employee name, job performed, hours worked per day, and a code. Journeyman employees have a code of J, apprentices a code of A, and casual labor a code of C. The output consists of the employee name, job performed, hours worked, and calculated pay. Journeyman employees receive $20.00 per hour. Apprentices receive $15.00 per hour. Casual Labor receives $10.00 per hour.
Answer:
1. Start
2. Input Name, Jobs, Hours, Code
3. If Code == 'J' then
3.1 Pay = 20.00 * Hours
4. Else if Code == 'C' then
4.1 Pay = 15.00 * Hours
5. Else if Code == 'A' then
5.1 Pay = 10.00 * Hours
6. Output Name, Job, Hours, Pay
Explanation
This line starts the Pseudocode
1. Start
This line gets user inputs
2. Input Name, Jobs, Hours, Code
The following if and else statement determine the pay
3. If Code == 'J' then
3.1 Pay = 20.00 * Hours
4. Else if Code == 'C' then
4.1 Pay = 15.00 * Hours
5. Else if Code == 'A' then
5.1 Pay = 10.00 * Hours
This line prints the required output
6. Output Name, Job, Hours, Pay

String has the following lexicographically-ordered substrings of length :
We then return the first (lexicographically smallest) substring and the last (lexicographically largest) substring as two newline-separated values (i.e., ava\nwel).
The stub code in the editor then prints ava as our first line of output and wel as our second line of output.
Solution:-
import java.util.Scanner;
public class Solution {
public static String getSmallestAndLargest(String s, int k) {
String smallest = "";
String largest = "";
smallest = largest = s.substring(0, k);
for (int i=1; i
String substr = s.substring(i, i+k);
if (smallest.compareTo(substr) > 0)
smallest = substr;
if (largest.compareTo(substr) < 0)
largest = substr;
}
return smallest + "\n" + largest;
}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String s = scan.next();
int k = scan.nextInt();
scan.close();
System.out.println(getSmallestAndLargest(s, k));
}
}
Answer:
Here is the JAVA program:
import java.util.*;
public class Solution { // class name
public static String getSmallestAndLargest(String s, int k) { //method that takes a string s and and integer k and returns lexicographically smallest and largest substrings
String smallest = ""; //stores the smallest substring
String largest = ""; //stores the largest substring
smallest = largest = s.substring(0, k); //sets the smallest and largest to substring from 0-th start index and k-th end index of string s
for(int i = 0;i<=s.length()-k;i++){ //iterates through the string s till length()-k
String subString = s.substring(i,i+k); //stores the substring of string s from ith index to i+k th index
if(i == 0){ //if i is equal to 0
smallest = subString; } //assigns subString to smallest
if(subString.compareTo(largest)>0){ //checks if the subString is lexicographically greater than largest
largest = subString; //sets subString to largest
}else if(subString.compareTo(smallest)<0) //checks if the subString is lexicographically less than smallest
smallest = subString; } //sets subString to smallest
return smallest + "\n" + largest; } //returns the lexicographically smallest and largest substrings
public static void main(String[] args) { //start of main method
Scanner scan = new Scanner(System.in); //creates Scanner object
String s = scan.next(); //scans and reads input string from user
int k = scan.nextInt(); //scans and reads integer k from user
scan.close();
System.out.println(getSmallestAndLargest(s, k)); } } //calls method by passing string s and integer k to it to display lexicographically smallest and lexicographically largest substring
Explanation:
The program takes a string s and an integer k and passes them to function getSmallestAndLargest that returns the lexicographically smallest and lexicographically largest substring. The method works as follows:
Lets say s = helloworld and k = 3
smallest = largest = s.substring(0, k);
s.substring(0, k); is returns the substring from 0th index to k-th index so it gives substring hel
for(int i = 0;i<=s.length()-k;i++) This loop iterates through the string s till s.length()-k times
s.length()-k is equal to 7 in this example
At first iteration:
i = 0
i<=s.length()-k is true so program enters the body of loop
String subString = s.substring(i,i+k); this becomes:
subString = s.substring(0,3);
subString = "hel"
if(i == 0) this is true so:
smallest = subString;
smallest = "hel"
At second iteration:
i = 1
i<=s.length()-k is true so program enters the body of loop
String subString = s.substring(i,i+k); this becomes:
subString = s.substring(1,4);
subString = "ell"
if(subString.compareTo(smallest)<0) this condition is true because the subString ell is compared to smallest hel and it is lexographically less than smallest so :
smallest = subString;
smallest = "ell"
So at each iteration 3 characters of string s are taken and if and else if condition checks if these characters are lexicographically equal, smaller or larger and the values of largest and smallest change accordingly
After the loop ends the statement return smallest + "\n" + largest; executes which returns the smallest and largest substrings. So the output of the entire program with given example is:
ell wor
Here ell is the lexicographically smallest substring and wor is lexicographically largest substring in the string helloworld

twentieth century music has adopted the sounds of the modern period which include synthesizers electronics and computers
Answer: True
Explanation:
The 20th century (1900s) saw an increase in the kind and variety of music available. This was down to many innovations in the musical industry in the 20th century such as multitrack recording that made music much more accessible and easier to produce.
With these innovations as well as the advent of the age of computers, musicians and composers were able to included synthesizers and electronics in their music as well as using computers such that new sounds enveloped the world from jazz to rock to jazz fusion.
c Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call FindMax() twice in an expression.
Answer:
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
Explanation:
In the statement, maxSum is a double type variable which is assigned the maximum of the two variables numA numB PLUS the maximum of the two variables numY numZ using which are found by calling the FindMax function. The FindMax() method is called twice in this statement one time to find the maximum of numA and numB and one time to find the maximum of numY numZ. When the FindMax() method is called by passing numA and numB as parameters to this method, then method finds if the value of numA is greater than that of numB or vice versa. When the FindMax() method is called by passing numY and numZ as parameters to this method, then method finds if the value of numY is greater than that of numZ or vice versa. The PLUS + sign between the two method calls means that the resultant values returned by the FindMax() for both the calls are added and the result of addition is assigned to maxSum.
