It may be  obvious that he has a question.  It's not the least
bit obvious what that question is.

He should spend less time trying to generate "gifted speach"
and more time learning how to ask an understandable, meaningful
question.  The link which you ignored explains how to do that.

In your original post, it's not very clear what you mean by
"hash values to keys" means nor what alternatives you're asking
about. If you're trying to learn about hashing algorithms, then
google "hashing algorithms" and read the first half-dozen hits.

The first two are Wikipedia articles which are both quite good
and are almost certainly available in your native lanauge.
