According to its structure I'd say that this is SEAL (<span>Software-Optimized Encryption Algorithm). It's difficult to describe how it works, because this kind of ciphers is very tricky. This algorithm uses 160 bit key and it uses 3 tables (R, S, T) to encode and decode.

I'll attach the image where you can see a process of creating a pseudo-random function:

Write a program that converts a number entered in Roman numerals to decimal. your program should consist of a class, say, Roman.
arlik [135]

Answer:

The code is given below in Java with appropriate comments

Explanation:

import java.util.*;

public class RomantoDecimal {

    public static void main(String[] args)

    {

         Scanner SC = new Scanner(System.in);

         RomantoDecimal r = new RomantoDecimal();

         System.out.println("Enter a Roman number :");

         // INPUT A ROMAN NUMBER

         String rNum = SC.next();

         // CALL convertToDecimal FOR CONVERSION OF ROMAN TO DECIMAL

         r.convertToDecimal(rNum);

    }

    // M=1000, D=500, C=100, L=50, X=10, V=5, I=1

    public void convertToDecimal(String roamNo)

    {

         int number = 0;

         // TEACK EACH DIGIT IN THE GIVEN NUMBER IN REVERSE ORDER

         for (int i = roamNo.length() - 1; i >= 0; i--)

Assume values 10, 20, 30, and 40 are entered in the cell range A1:A4. Cell A10 contains the formula: =A1+A2+A3+A4 and displays v
r-ruslan [8.4K]

Answer:

The formula and value to this question is "=A1+A3+A4+A5 with value 100"

Explanation:

The explanation of the given question as follows:

  • In question, it is defined that four cells that are "A1, A2, A3, and A4"  contains value that are "10, 20, 30, and 40".
  • To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
  • If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".

Reil [10]

B, Parallel ports are faster than serial ports.

A parallel port can move a set of 8 bits at a time on eight different wires, it uses a 25 pin connector, called a DB-25 connector, whereas a serial port only has a DB-9 connector.

Assume inputFile is a Scanner object used to read data from a text file that contains a number of lines. Each line contains an a
anzhelika [568]

Answer:

words.hasNext()

Explanation:

Given the code snippet below:

  1.        while (inputFile.hasNextLine()) {
  2.            String word = "";
  3.            String line = inputFile.nextLine();
  4.            Scanner words = new Scanner(line);
  5.            while (words.hasNext()) {
  6.                word = words.next();
  7.            }
  8.            System.out.println(word); }
  9.    }

We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.
