Binary with 0 and 1 is good, but binary with only 0 is even better! Originally, this is a concept designed by Chuck Norris to send so called unary messages.

Can you write a program that can send and receive this messages?

Rules

The input message consists of ASCII characters between 32 and 127 (7-bit)
The encoded output message consists of blocks of 0
A block is separated from another block by a space
Two consecutive blocks are used to produce a series of same value bits (only 1 or 0 values):

First block is always 0 or 00. If it is 0, then the series contains 1, if not, it contains 0
The number of 0 in the second block is the number of bits in the series


Example
Let’s take a simple example with a message which consists of only one character (Letter 'C').'C' in binary is represented as 1000011, so with Chuck Norris’ technique this gives:

0 0 - the first series consists of only a single 1
00 0000 - the second series consists of four 0
0 00 - the third consists of two 1

So 'C' is coded as: 0 0 00 0000 0 00
Second example, we want to encode the message "CC" (i.e. the 14 bits 10000111000011) :

0 0 - one single 1
00 0000 - four 0
0 000 - three 1
00 0000 - four 0
0 00 - two 1

So "CC" is coded as: 0 0 00 0000 0 000 00 0000 0 00
Note of thanks
Thanks to the author of the original kata. I really liked this kata. I hope that other warriors will enjoy it too.
