Chuck Norris Unary Code

The Chuck Norris code is a unary code, with a single character: zero. The unary code is a conversion of the binary code according to the sequences of 0 and 1 repeated.

A sequence of N times 0 is coded 00 followed by N times 0.

A sequence of N times 1 is coded 0 followed by N times 0.

Example: 00011110 is divided into segments of 0 and 1 consecutive: 000,1111,0 then transcribed:

Example: The encoded message is 00 000 0 0000 00 0

By default the clear message is first coded in 7bit binary (via the ASCII table).

The message is unary, normally composed only of zeros. To recompose the corresponding binary, segment the sequences of zeros in groups of 2. The first set of zeros in each group is alternately either 0 (for a 1 bit) or 00 (for a 0 bit), the second set of zeros corresponds to the number of repetitions of this bit.

Example: 0 0000 (ie 0 followed by 4 zeros 0000) for 1 repeated 4 times or 1111

Example: 00 0 (ie' 00 'followed by 1 zero) for' 0 'repeated once or' 0 '

The message consists of a single character: the 0 (and a separator, usually a space character).

The message alternates 0 and 00 every 2 groups of 0.

The 0 character can be substituted by a search and replace by any other character.

ASCII encoding can be replaced by another type of encoding (A1Z26, Unicode, etc.)

ASCII encoding can be 7-bit or 8-bit.

Chuck Norris is the name given by the Codingame website for one of his tests that deals with this unary code.
