"If possible, always bring print-outs of your slides for your audience
members." Is this good advice?
A. If you can, this is always recommended, unless you are assured
everyone will have a tablet and you can share the files online.
B. No, this is not good advice since handouts rarely help the
audience in any manner. The only thing that matters is what the
speaker says.
C. Not really, since it is a lot of work, requiring a lot of paper, and
most people will not need the handouts.
D. Not really, because audience members will never need to review
slide information.
Answer:
Answer is A I just take the quiz.
Unless you are certain that everyone will have a tablet and can share the files online, it is always suggested to carry the print-out files of the slides.
Why it is important to bring the print-out files of the slides?When the slides have a lot of component part, it's a good thought to overlap the copies of the presentation. A presentation is a misfortune medium for communicating ecumenical information.
If the audience has print-out files of the slides, they will be more focused on the themes that want to express rather than recalling every detail.
Unless a person knowing for sure that everyone will have a tablet and will be able to share the files online, it is always a good idea to have the print-out files of the slides with you.
Therefore, option A is correct.

Hackers crack hash functions by finding collisions or pre-generating millions of hashes and comparing them until find the one generated it.
A. True
B. False
Answer:
A. True
Explanation:
Most of the attacks on hash functions are based on finding collisions (so 2 different plain texts will match the same hash) or pre-generating millions of hashes and comparing them until you find the plain that generated it.
If a hash algorithm is reverse-engineerable or can be attacked that way, it's not a good hash algorithm.

Hi, can someone please help me with this? I've been having a lot of trouble with it.
The assignment
Your job in this assignment is to write a program that takes a message as a string and reduces the number of characters it uses in two different set ways. The first thing your program will do is ask the user to type a message which will be stored as a String. The String entered should be immediately converted to lowercase as this will make processing much easier. You will then apply two different algorithms to shorten the data contained within the String.
Algorithm 1
This algorithm creates a string from the message in which every vowel (a, e, i, o, and u) is removed unless the vowel is at the very start of a word (i.e., it is preceded by a space or is the first letter of the message). Every repeated non-vowel character is also removed from the new string (i.e., if a character appears several times in a row it should only appear once at that location). So for example the string "I will arrive in Mississippi really soon" becomes "i wl arv in mssp rly sn".
After applying this algorithm, your program should output the shortened message, the number of vowels removed, the number of repeated non-vowel characters removed, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.
Algorithm 2
This algorithm creates a string by taking each unique character in the message in the order they first appear and putting that letter and the number of times it appears in the original message into the shortened string. Your algorithm should ignore any spaces in the message, and any characters which it has already put into the shortened string. For example, the string "I will arrive in Mississippi really soon" becomes "8i1w4l2a3r1v2e2n1m5s2p1y2o".
After applying this algorithm, your program should output the shortened message, the number of different characters appearing, and how much shorter the shortened message is than the original message. The exact format in which the program should print this information is shown in the sample runs.
Sample Run 1
Type the message to be shortened
This message could be a little shorter
Algorithm 1
Vowels removed: 11
Repeats removed: 2
Algorithm 1 message: ths msg cld b a ltl shrtr
Algorithm 1 characters saved: 13
Algorithm 2
Unique characters found: 15
Algorithm 2 message: 4t2h2i4s1m5e2a1g1c2o1u3l1d1b2r
Algorithm 2 characters saved: 8
Sample Run 2
Type the message to be shortened
I will arrive in Mississippi really soon
Algorithm 1
Vowels removed: 11
Repeats removed: 6
Algorithm 1 message: i wl arv in mssp rly sn
Algorithm 1 characters saved: 17
Algorithm 2
Unique characters found: 13
Algorithm 2 message: 8i1w4l2a3r1v2e2n1m5s2p1y2o
Algorithm 2 characters saved: 14
Milestones
As you work on this assignment, you can use the milestones below to inform your development process:
Milestone 1: Set up a program that takes a string input and converts all the letters to lowercase. Start implementing algorithm 1: create a counter variable and iterate through the characters of the String, incrementing this each time a vowel is encountered which is not preceded by a space or is at the start of the String. So at the end of the loop this counts the number of vowels that are not at the start of a word.
Milestone 2: Add further conditions (using else if) in your loop to count any non-vowel characters which appear immediately after the same character. Make a new empty String to hold the shortened message at the start of the code, then add a final else condition in the loop to add all characters which were not vowels or repeated letters to this String. Then print the statements for algorithm 1 using your counts and shortened message.
Milestone 3: Start implementing algorithm 2 by writing code that iterates through the String and checks that each character is not a space and has not already appeared in the word before that point. You will need to use nested loops - an outer loop to iterate through the String characters and an inner loop that looks through the previous characters up to that point - and a flag variable to record if a letter was found in the inner loop. Use a counter variable to count all such "unique" characters in the String.
Milestone 4: Add a second inner loop inside the outer loop from the previous which counts all appearances of a character that passes the tests from milestone 3. Add the character and the number of times it appears to another shortened message String (which should start as blank String). Finally, print the statements for algorithm 2 using your unique character count and shortened message.
Answer:
Scanner scan = new Scanner(System.in);
System.out.println("Type the message to be shortened");
String msg = scan.nextLine();
System.out.println();
msg = msg.toLowerCase();
String newStr = "";
System.out.println("Algorithm 1");
int vowels = 0;
int repeats = 0;
for(int i = 0; i < msg.length(); i++)
{
if((msg.substring(i, i +1).equals("a") || msg.substring(i, i+1).equals("e") || msg.substring(i, i +1).equals("i") || msg.substring(i, i+1).equals("o") || msg.substring(i, i +1).equals("u")))
{
if(i != 0 && !msg.substring(i -1, i).equals(" "))
{
vowels++;
}
else
newStr += msg.substring(i, i +1);
}
else if(i != 0 && msg.substring(i, i +1).equals(msg.substring(i -1, i)))
{
repeats++;
}
else
{
newStr += msg.substring(i, i +1);
}
}
System.out.println("\nAlgorithm 1");
System.out.println("Vowels removed: " + vowels);
System.out.println("Repeats removed: " + repeats);
System.out.println("Algorithm 1 message: " + newStr);
System.out.println("Algorithm 1 characters saved: " + (vowels + repeats));

// Only process if this character is not a space
if(!ltr.equals(" "))
{
/* Check whether this character has already appeared by

HELLLLPPPPPP Jerry needs to move his Turtle forward 25 pixels. Which line of code should Jerry use?
tom(25)
tom.forward(25)
tom.turtle(25)
tom.right(twenty-five)
If your turtle is defined and you named the variable tom, the code would be:
tom.forward(25)
Jerry should use the line of code tom.forward(25) to move his Turtle forward 25 pixels. The correct option is 2.
What is coding?The process of designing, writing, testing, and maintaining the source code of software programmes, websites, and other computer applications is referred to as coding.
Because the forward() method is used to move the turtle forward by a specified number of pixels or units, the line of code tom.forward(25) should be used to move the turtle forward by 25 pixels.
The turtle object is named Tom in this case, and the method forward() is called on it with the argument 25, indicating that the turtle should move forward 25 pixels.
Thus, the correct option is 2.
