Hello I want know the reason for which my question is migrated to stack-overflow? If this is not considered as a code-golf I will like to cite few example where compression in without standard library is the only way to solve the problem,for example MONS and MAGIC2
Every year one question also features in TLE (a shortening/optimizing contest where only C and C++ is allowed)
I have seen these type of question common in few others contest too,so I was inquisitive to compare various compression techniques and there utilization in code-golfing in order of get an idea about the most shortest and efficient compression technique feasible for implemenatation,however I am interested to know why this question is not suitable for codegolf.stackexchange, since as i am looking for shortest possible compression technique my question is not suitable for stack-overflow itself.
