Detailed Description

+

Encode a null terminated string using Run-length encoding

+
Author
serturx
+

Run-length encoding is a lossless compression algorithm. It works by counting the consecutive occurences symbols and encodes that series of consecutive symbols into the counted symbol and a number denoting the number of consecutive occorences.

+

For example the string "AAAABBCCD" gets encoded into "4A2B2C1D"
