Compilation of compression algorithms!

About compression algorithms, such as 1111112436666445555
After compression is 61, -3243, 46, 24, 45,
If there are the same characters, the first character is the same number of characters,
If different characters are connected together, the first character is a negative number, and its absolute value is the number of different characters, followed by different characters.
Do you understand?
Help me think of a way!

Good academic algorithm ~~~

A bit similar to the compression method of pcx images.

The conditions given by the host are not clear. First of all, in which environment this thing is running, 16-bit or 32-bit, this must be clearly stated; secondly, if it is 16-bit, if the same number of characters exceeds the length of that byte , What to do. Third, what to do if the length of different characters exceeds 7 bits (the highest bit is reserved for the matching bit).
If these situations are not explained clearly, it is impossible to write code. If you can write these conditions clearly, it will only take a few minutes to write code.

这是游程算法，多用在图形压缩中。
