<h2>Answer:</h2>
Truck drivers probably can't see your vehicle if you cannot see them in their side mirror
<h2>Explanation:</h2>
In driving terminology there is a term called the bind spot. Blind spot is the area where the driver is not able to see the vehicle behind him and this area is present just behind the truck and very close to the gates of the car. Since trucks do not have the rare mirror therefore if a car is present in their blind spot they wont be able to see it. The driver behind the truck can spot it if he does not see the truck driver in the side mirror of the truck.

Answer:
if(y==10)
{
x=0; // assigning 0 to x if y equals 10.
}
else
{
x=1; // assigning 1 to x otherwise.
}
Explanation:
In the if statement i have used equal operator == which returns true if value to it's right is equal to value to it's left otherwise false.By using this operator checking value of y and if it is 10 assigning 0 to x and if it is false assigning 1 to x.
Answer:
It we were asked to develop a new data compression tool, it is recommended to use Huffman coding since it is easy to implement and it is widely used.
Explanation:
The pros and the cons of Huffman coding
Huffman coding is one of the most simple compressing encoding schemes and can be implemented easily and efficiently. It also has the advantage of not being patented like other methods (e.g. arithmetic codingfor example) which however are superior to Huffman coding in terms of resulting code length.
One thing not mentioned so far shall not be kept secret however: to decode our 96 bit of “brief wit” the potential receiver of the bit sequence does need the codes for all letters! In fact he doesn’t even know which letters are encoded at all! Adding this information, which is also called the “Huffman table” might use up more space than the original uncompressed sentence!
However: for longer texts the savings outweigh the added Huffman table length. One can also agree on a Huffman table to use that isn’t optimized for the exact text to be transmitted but is good in general. In the English language for example the letters “e” and “t” occur most often while “q” and “z” make up the least part of an average text and one can agree on one Huffman table to use that on average produces a good (=short) result. Once agreed upon it doesn’t have to be transmitted with every encoded text again.
One last thing to remember is that Huffman coding is not restricted to letters and text: it can be used for just any symbols, numbers or “abstract things” that can be assigned a bit sequence to. As such Huffman coding plays an important role in other compression algorithms like JPG compression for photos and MP3 for audio files.
The pros and the cons of Lempel-Ziv-Welch
The size of files usually increases to a great extent when it includes lots of repetitive data or monochrome images. LZW compression is the best technique for reducing the size of files containing more repetitive data. LZW compression is fast and simple to apply. Since this is a lossless compression technique, none of the contents in the file are lost during or after compression. The decompression algorithm always follows the compression algorithm. LZW algorithm is efficient because it does not need to pass the string table to the decompression code. The table can be recreated as it was during compression, using the input stream as data. This avoids insertion of large string translation table with the compression data.
Answer:
See the code snippet below
Explanation:
import java.util.Scanner;
public class LabProgram{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Please enter first number: ");
int firstNumber = scan.nextInt();
System.out.println("Please enter second number: ");
int secondNumber = scan.nextInt();
maxMagnitude(firstNumber, secondNumber);
}
public static int maxMagnitude(int firstValue, secondValue){
System.out.println(Math.max(firstValue, secondValue));
}
}
