Best Compression algorithm for a sequence of integers

Question

I have a large array with a range of integers that are mostly continuous, eg 1-100, 110-160, etc. All integers are positive. What would be the best algorithm to compress thi

Answer 1

If you have series of repeated values RLE is the easiest to implement and could give you a good result. Nontheless other more advanced algorithms that take into account the entrophy such as LZW, which is now patent-free, can usually achive a much better compression.

You can take a look at these and other lossless algorithms here.
