chained hashing of integers C++

Posted 17 November 2012 - 08:34 AM

Hello everyone, I am looking for a systematic approach to hash random numbers (0 to 200) into an array of 70 elements, evenly distributed if possible. So far I have tried key % 70 but this expression does not use up all 70 elements.

This hash function should undoubtably fill up a 70 element array if your hashing 0 - 200. Can you post what you have tried so far?

If it is not filling up then it is only because you are probably not adding enough entries to need every position.
