in thread Bidirectional lookup algorithm? (Updated: further info.)

Essentially, that is what I am doing.

One array of structs contains the paired data. This is ordered by hashing one of the values.

A parallel array of ints contains indexes into the first array and are ordered by hashing the second value,

Once I've fixed a couple of edge cases I know about, tested it some more, and probably moved it from linear to hopscotch probing, I'll post the code in this thread.
