Explanation:
import java.util.*;
class Main {
public static void main(String[] args) {
//PrompT the User to enter a String
System.out.println("Enter a sentence or phrase: ");
//Receiving the string entered with the Scanner Object
Scanner input = new Scanner (System.in);
String string_input = input.nextLine();
//Print out string entered by user
System.out.println("You entered: "+string_input);
//Call the first method (GetNumOfCharacters)
System.out.println("Number of characters: "+ GetNumOfCharacters(string_input));
//Call the second method (OutputWithoutWhitespace)
System.out.println("String with no whitespace: "+OutputWithoutWhitespace(string_input));
}
//Create the method GetNumOfCharacters
public static int GetNumOfCharacters (String word) {
//Variable to hold number of characters
int noOfCharactersCount = 0;
//Use a for loop to iterate the entire string
for(int i = 0; i< word.length(); i++){
//Increase th number of characters each time
noOfCharactersCount++;
}
return noOfCharactersCount;
}
//Creating the OutputWithoutWhitespace() method
//This method will remove all tabs and spaces from the original string
public static String OutputWithoutWhitespace(String word){
//Use the replaceAll all method of strings to replace all whitespaces
String stringWithoutWhiteSpace = word.replaceAll(" ","");
return stringWithoutWhiteSpace;
}

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. If random number generated is 0, then print "there is no wind", if 1 to 6 then print "this is a breeze", if 7 to 9 "this is a gale", if 10 to 11 print "this is a storm", if 12 print "this is a hurricane!". (Hint: use range or multiple values in case statements like case {1,2,3,4,5,6})
Required:
Re-write this switch statement as one nested if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]);
switch ranforce
case 0
disp('There is no wind')
case {1,2,3,4,5,6}
disp('There is a breeze')
case {7,8,9}
disp('This is a gale')
case {10,11}
disp('It is a storm')
case 12
disp('Hello, Hurricane!')
end
Answer:
The equivalent if statements is:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
The solution is straight forward.
All you need to do is to replace the case statements with corresponding if or else if statements as shown in the answer section
According to Darwin’s theory of evolution, differences between species may be a result of which of the following?
a) The disuse of body structures
b) The transmission of acquired characteristics
c) Natural selection
d) Mutagenic agents
Answer:
The answer is C Natural selection
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
According to Darwin’s theory of evolution, differences between species may be a result of Natural selection. Thus the correct option is C.
What is Darwin’s theory of evolution?According to Darwin, all species descended from a single ancestor, species can change through time, and new species can arise from existing ones which makes them interconnected with common traits.
Natural selection of traits in a species that would help the species in its survival is the process that drives diversification, the evolutionary process through which new biological species form.
Natural selection is the evolutionary mechanism stating that with many resources available in nature, creatures with genetically inherited features that promote survival and reproduction will typically produce more offspring than their conspecific competitors.
Therefore, option C is appropriate.

What is the maximum number of VLANs that can be configured on a switch supporting the 802.1Q protocol? Why?
Answer:
4096 VLANs
Explanation:
A VLAN (virtual LAN) is a group of devices on one or more LAN connected to each other without physical connections. VLANs help reduce collisions.
An 802.1Q Ethernet frame header has VLAN ID of 12 bit VLAN field. Hence the maximum number of possible VLAN ID is 4096 (2¹²). This means that a switch supporting the 802.1Q protocol can have a maximum of 4096 VLANs
A lot of VLANs ID are supported by a switch. The maximum number of VLANs that can be configured on a switch supporting the 802.1Q protocol is 4,094 VLANS.
All the VLAN needs an ID that is given by the VID field as stated in the IEEE 802.1Q specification. The VID field is known to be of 12 bits giving a total of 4,096 combinations.But that of 0x000 and 0xFFF are set apart. This therefore makes or leaves it as 4,094 possible VLANS limits. Under IEEE 802.1Q, the maximum number of VLANs that is found on an Ethernet network is 4,094.

Write a program named as calcPrice.c that formats product information entered by the user and calculate the total amount of purchase.
Answer:
Here is the calcPrice.c program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main method
int itemNo, month, day, year, quantity; //declares variables to hold item number, quantity, and date
float unitPrice; //declare variable to hold price per unit
printf("Enter item number: "); // prompts user to enter item number
scanf("%d", &itemNo); //reads item number from user and stores it in itemNo variable
printf("Enter unit price: "); // prompts user to enter unit price
scanf("%f", &unitPrice); //reads input unit price and stores it in unitPrice variable
printf("Enter quantity: "); //prompts user to enter quantity
scanf("%d", &quantity); //reads input quantity and stores it in quantity variable
printf("Enter purchase date (mm/dd/yyyy): "); //prompts user to enter purchase date
scanf("%d/%d/%d", &month, &day, &year); //reads input date and stores it in month, day and year variables
float totalAmount = unitPrice * quantity; //computes the total amount
printf("\nItem\tUnit Price\tQTY\tPurchase Date\tTotal Amount\n"); //displays the item, unit price, qty, purchase data and total amount with tab space between each
printf("%d\t$%5.2f\t%d\t%.2d/%.2d/%d\t$%5.2f\n", itemNo, unitPrice,quantity, month, day, year,totalAmount); } //displays the values of itemNo, unitPrice, quantity, month, day, year and computed totalAmount with tab space between each
Explanation:
Lets suppose user enters 583 as item number, 13.5 as unit price, 2 as quantity and 09/15/2016 as date so
itemNo = 583
unitPrice = 13.5
quantity = 2
month = 09
day = 15
year = 2016
totalAmount is computed as:
totalAmount = unitPrice * quantity;
totalAmount = 13.5* 2
totalAmount = 27.00
Hence the output of the entire program is:
Item Unit Price QTY Purchase Date Total Amount
583 $ 13.50 2 09/15/2016 $ 27.00

Technician A says that the last step in the diagnostic process is to verify the problem. Technician B says that the second step is to perform a thorough visual inspection. Who is correct
Answer:
The answer to this question is given below in the explanation section. However, the correct option is Technician B.
Explanation:
There are eight steps procedures to diagnose the engine.
Step 1 Verify the Problem
Step 2 Perform a Thorough Visual Inspection and Basic Tests
Step 3 Retrieve the Diagnostic Trouble Codes (DTCs)
Step 4 Check for Technical Service Bulletins (TSBs)
Step 5 Look Carefully at Scan Tool Data
Step 6 Narrow the Problem to a System or Cylinder
Step 7 Repair the Problem and Determine the Root Cause
Step 8 Verify the Repair and Clear Any Stored DTCs
So the correct technician is Technician B that says that the second step is to perform a thorough visual inspection.
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.

Lexicographical Order, also known as alphabetic or dictionary order, orders characters as follows:
For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball.
A substring of a string is a contiguous block of characters in the string. For example, the substrings of abc are a, b, c, ab, bc, and abc.
Given a string, , and an integer, , complete the function so that it finds the lexicographically smallest and largest substrings of length .
Input Format
The first line contains a string denoting .
The second line contains an integer denoting .

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
The screenshot of the program along with its output is attached.
