no
If the one's complement of the code is equal to the nine's complement of the code, then it is called a self complementing code.

A self-complementing binary code is a type of binary code in which the complement of a code word can be derived from the code word itself by simply inverting its bits. In this code, the representation of a number and its complement share a specific relationship, such that if you take a code word and flip all its bits, you get the code for its complement. This feature simplifies certain operations in digital systems, particularly in arithmetic and logic circuits. An example of a self-complementing code is the 4-bit binary-coded decimal (BCD) where the codes for the digits 0-9 are designed to facilitate easy complementing.
a binary code is self complementary if complement of any code word is again a code .in self completing codes 9's complement of a number can be obtained by interchanging 0's and 1's.
A self complementing code is one thats 9's complement in decimal is the 1's complement in binary.Ex: The 9's complement of 7 is 2 in decimal. In 2421 code, and .
9's complement of a decimal number represented in 2421 code is easily obtained by replacing the 1s with 0s,and 0s with 1s,so 2421 code is called a self complementing code.example-2421 of '2' is '0010',after replacing the 0s with 1s and 1s with 0s weget '1101' which is the 2421 of '7'(9s complement of 2 is 7). Thus 2421 code is self complementary.
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.
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.
The airport code for Gray Army Airfield is GRF.
The Code of Marcia Gray was created on 1916-03-16.
