In reverse binary representation, the bits are output in reverse order. The algorithm used for this conversion is as follows:

While the input integer (x) is greater than 0:
Output the remainder of x % 2 (either 0 or 1).
Update x to x / 2 (integer division).
Repeat steps 1-3 until x becomes 0.

Program Code

Below is the Java program that implements the algorithm described above:


import java.util.Scanner;
public class Lab2_1 {
public static void main(String[] args) {
Scanner stdin = new Scanner(System.in);
    System.out.print("Please type in a positive integer: ");
    int integer = stdin.nextInt();
    String binary = "";

    while (integer > 0) {
        binary += integer % 2;
        integer /= 2;
    }

    System.out.println("Reverse Binary is " + binary);
}
}

Explanation of the Code

The Java program begins by importing the Scanner class to facilitate user input.

It then defines the Lab2_1 class with a main method. Inside the main method:

A Scanner object named stdin is created to read user input.
The user is prompted to enter a positive integer using System.out.print.
The entered integer is stored in the variable integer.
A string variable binary is initialized to an empty string to store the reverse binary representation.
A while loop is used to implement the reverse binary conversion algorithm:
- The remainder of integer % 2 (either 0 or 1) is appended to the binary string.
- The value of integer is updated to integer / 2 using integer division.
- This process continues until integer becomes 0.
Finally, the reverse binary representation stored in binary is printed to the console using System.out.println.

Example

For instance, if the user enters the input:6

The program will produce the following output:


Please type in a positive integer: 6
Reverse Binary is 011

Explanation: The input integer 6 is converted to binary as 110, but since we are using reverse binary, the program outputs 011.

Conclusion

This lab assignment has successfully demonstrated how to create a Java program that converts a positive integer into reverse binary representation. The program utilizes a straightforward algorithm and user input to generate the desired output. Understanding binary representation and programming logic is crucial for such tasks, and this assignment serves as a practical example of these concepts.
