In gray code only one bit position changes between any two successive (nearby) entries. This allows us to group the terms producing the same (normally 1) and eliminate the variable corresponding to the common bit position. As the K-map is used for reduction of min terms, this approach is used. It is the basis of the K-map itself.
The Gray Code is a type of binary code developed by a programmer named Frank Gray. Gray code is a binary numeral system that differ than normal binary code, and is used widely to detect errors in software.
characteristic of Gray code
One disadvantage of Gray code is that it is not as intuitive for human understanding compared to binary code. Another drawback is that Gray code is not as efficient in terms of mathematical operations, such as addition and subtraction, compared to binary code. Additionally, Gray code requires more bits to represent the same range of values as binary code, which can result in increased complexity and storage requirements.
Gray code is used primarily in digital systems to prevent errors during the transition between values. Unlike binary code, where multiple bits may change simultaneously, Gray code ensures that only one bit changes at a time. This minimizes the possibility of misreading values, especially in applications like rotary encoders and digital communication where reliable signal interpretation is crucial. Additionally, Gray code simplifies the design of certain types of circuits, such as in error detection and correction systems.

The Code of Marcia Gray was created on 1916-03-16.
In order to convert decimal to gray code use an array of int containing either a one or a zero at each position. A BitArray could also be used and might be a better choice.
Gray code
Gray code is a 'reflected code', why is it named so will be illustrated soon. The advantage of Gray code over binary code is that only one bit in the code group changes when going from one number to the next. By, Ashish Kumar (Roh, Nawada, Bihar)

Gray code is primarily used in digital systems for position encoding and error correction. One application is in rotary encoders, where the Gray code allows for smooth and error-free transitions between positions, as only one bit changes at a time. Another application is in error detection for data transmission, where Gray code helps minimize errors during signal transitions, especially in noisy environments. Diagrams for these applications typically show the binary and corresponding Gray code representations, illustrating how adjacent values differ by only one bit.
