It's a small pet project for learning of python and GitHub services.
This project including writing simple algoritm and Its improvement.

compression

The logic of the compression is to write sequences of identical bytes into two bytes and their counter.

For example:

• 2, 2, 2, 2, 2, 2 => 2, 2, 4
• 7, 9, 3, 3, 3, 3, 10, 11 => 7, 9, 3, 3, 2, 10, 11
• 3, 3 => 3, 3, 0 - this is a flaw in the algorithm

decompression

The decompression logic is to find two identical consecutive bytes.
The next byte is already a counter and lets you know how many of these bytes
you still need to add to the unpacked sequences.

For example:

• 3, 3, 0 => 3, 3
• 2, 2, 1 => 2, 2, 2
• 0, 7, 7, 5, 11 => 0, 7, 7, 7, 7, 7, 7, 7, 11
