Details:

The Gray code conversion algorithm is a bit manipulation technique used to convert a binary number into its Gray code equivalent. Gray code, unlike regular binary representation, ensures that two successive values differ by only one bit, which is critical in minimizing errors in digital systems during transitions.

Steps of the Algorithm:
Input: Start with a binary number n which you want to convert to Gray code.
Right Shift the Binary Number: Perform a right shift operation on n by one position. This means moving all the bits of the number one step to the right, dropping the least significant bit (LSB), and filling the most significant bit (MSB) with a zero.
XOR Operation: Apply the XOR operation between the original number n and its right-shifted version. The XOR (exclusive OR) operation returns 1 if the bits are different and 0 if the bits are the same.
Result: The resulting number after the XOR operation is the Gray code equivalent of the original binary number.
Detailed Example:
For the binary number 5 (which is 101 in binary):

Step 1: Right shift 5 by one bit, resulting in 010.
Step 2: Perform the XOR operation between 101 and 010, which yields 111.
Step 3: The result 111 is the Gray code equivalent of 5, which is 7 in decimal.
Key Insights:
Bitwise Efficiency: The algorithm utilizes bitwise operators (right shift and XOR), which are very efficient for performing operations directly at the bit level.
Time Complexity: The algorithm runs in constant time, O(1), as it performs only a few bitwise operations regardless of the size of the input.
Space Complexity: The space complexity is also constant, O(1), as it uses only a small number of variables.
Applications of Gray Code:
Error Prevention in Digital Systems: Since only one bit changes between consecutive Gray code values, it reduces the chances of errors during transitions between states, especially in hardware circuits like rotary encoders or analog-to-digital converters.
Logic Circuit Simplification: In digital logic design, Gray code is often used in Karnaugh maps to minimize the number of transitions and simplify boolean expressions.
This algorithm is a simple yet powerful bit manipulation technique widely used in digital systems for error minimization and efficient state transitions.
