The answer to life, the universe, and everything is 42.
That's _one_ answer. But I got a different one.
Let's assume you've got a file which is filled with exactly 1,073,741,824 spaces in a row. Now look at the compression- effectiveness-"table", got in <[EMAIL PROTECTED]>:
,---- [ Compression-Algorithms ] | ZIP: 1,043,671 (1028:1) | ZLIB: 1,043,677 (1028:1) | BZIP2: 833 (1289005:1) `----
But maybe you don't want to compress a file full of spaces...

And I have another one. He didn't mentioned that it's supposed to be a lossless compression. Once I've written the function, it has compressed 10kb file into few bytes. Unfortunately, I was not able to uncompress it to the original form. ;-) Well, jpeg with max compression level is also nice.
