Tool for encoding messages in unary code according to the Chuck Norris method of encoding a series of N consecutive bits by replacing 1 with 0 and 0 with 00 respectively followed by N zeros.

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:__ Code the message 00011110 by dividing it into segments of consecutive 0 and 1: 000,1111,0 then transcribed:

000 | 00 000 |

1111 | 0 0000 |

0 | 00 0 |

The complete encoded message is 00 000 0 0000 00 0

By default the plain 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.
