A) <span>unauthorized duplication of software </span>
<u>Answer:</u>
<em>using System;
</em>
<em>public class Program
</em>
<em>{
</em>
<em> public static void Main()
</em>
<em> {
</em>
<em> String input ;
</em>
<em> while(true)
</em>
<em> {
</em>
<em> input = Console.ReadLine();
</em>
<em> if(input.Equals(""quit""))
</em>
<em> break;
</em>
<em> Reverse_String(input);
</em>
<em> }
</em>
<em> return;
</em>
<em> }
</em>
<em>static void Reverse_String(string input_text)
</em>
<em>{
</em>
<em> char[] text = input_text.ToCharArray();
</em>
<em> Array.Reverse(text);
</em>
<em> Console.WriteLine(text);
</em>
<em>}
</em>
<u>Explanation:</u>
<em>In the above program a separate function is written to reverse the string.</em>
This method takes the string as an argument and place it in a array and then use the built-in function reverse and print the reversed string in the console.
<em>In the main(), the input is obtained from the console and it is passed to the reversestring().

Answer:
code = 010100000001101000101
Explanation:
Steps:
The inequality yields 
, where M = 16. Therefore,
The second step will be to arrange the data bits and check the bits. This will be as follows:
Bit position number Check bits Data Bits
21 10101
20 10100
The bits are checked up to bit position 1
Thus, the code is 010100000001101000101

Answer:
C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.
Explanation:
Byte pair encoding is a form of encoding in which the most common pairs of consecutive bytes of data are replaced by a single byte which does not occur within the set of data.
For example, if we has a string ZZaaAb, it can be encoded if the pairs of string ZZ are replaced by X and the second pair by Y. So, our data now becomes XYAb.
To get our original data, that is decode it, we just replace the data with the keys X = ZZ and Y = aa thus allowing our original data to be restored.
Since our original string is restored without loss of data, it implies that <u>byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.</u>
