Ruby Example: Write a program to convert the Binary number to Gray code using recursion.
Submitted by Nidhi, on December 27, 2021

Problem Solution:

In this program, we will create an integer number initialized with binary value and then we will convert the Binary number to the Gray code using recursion.

Program/Source Code:

The source code to convert the Binary number to Gray code using recursion is given below. The given program is compiled and executed successfully.

# Ruby program to convert the Binary number
# to Gray code using recursion

def bin2gray(n)
if !(n>0)
return 0;
end
a = n % 10;
b= n / 10 % 10;

if (a>0 && !(b>0)) || (!(a>0) && (b>0))
return (1 + 10 * bin2gray(n / 10));
end

return (10 * bin2gray(n / 10));
end

number = 11011011;

result = bin2gray(number);

print "Gray code is: ",result;

Output:

Gray code is: 10110110

Explanation:

In the above program, we created an integer number number initialized with 11011011. Then we converted the given Binary number to the Gray code using recursive function bin2gray(). After that, we printed the result.
