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.

What is meant by self complementing binary codes?
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.
What is mean by self completing code?
A self complementing code for Base-10 is a code for which the complement of a given encoded digit d[0-9] will result in 9-d, the 9's complement.To encode Base-10 numbers in binary, we need to be able to represent 10 values [0-9] which means we require 4 bits because 3 bits can represent 8 values which is not enough; 4 bits can represent 16 values, which is more than we need, but we don't have (or want) fractional bits.There are numerous encoding schemes possible within these 4 bits, the most intuitive of which is the 8-4-2-1 scheme, or straight binary encoding of the decimal value. To encode 12 using 8-4-2-1, you would separately encode [1] and [2] as their respective binary representations [0001] and [0010].The 9's complement is relevant in the context of binary encoding decimal/Base-10 numbers because 9 is the largest value required when encoding Base-10 numbers.Your example implies Base-16, displayed as decimal, for which you are correctly generating the 15's complement rather than the 9's complement. 8-4-2-1 is intuitively a self complementing code for Base-16, because taking the complement of a 4 digit binary number is the same as subtracting it from 15.The same cannot be said for a Base-10 number represented the same way, because we are representing only 10 values in 16 member code space, which is why a number of more intricate systems have been devised to generate self-complementing codes for representation of decimal numbers in 4 digit binary numbers.Table 13.1 in the related link shows two self-complementing codes for decimal encoding, namely the 8,4,-2,-1 and excess-3 encoding schemes, and the subsequent section describes the purpose and theory behind self-complementing codes.

Why excess 3 is called self complimentary code?
Excess-3 (XS-3) is called a self-complementary code because the code for a digit and its complement (the digit subtracted from 9) can be derived directly from its representation. In XS-3, each decimal digit is represented by a 4-bit binary number that is equivalent to the digit plus three. For example, the XS-3 encoding of the digit '0' is '0011' (which is 3 in binary) and the encoding for '9' is '1100' (which is 12 in binary). When you take the 4-bit binary representation of a digit and its complement, they effectively mirror each other across the halfway point of the code, making the system self-complementary.
