It is a library to compress and uncompress arrays of integers very fast. The assumption is that most (but not all) values in your array use much less than 32 bits, or that the gaps between the integers use much less than 32 bits. These sort of arrays often come up when using differen...
This can’t be changed in Java, so if you need another path to work with the convention is to define a wd variable. os.root: The root of the filesystem. os.home: The home directory of the current user. os.temp()/os.temp.dir(): Creates a temporary file/folder and returns the ...
