Well before we go on further
| Code: |
hash = ( any_number * FNV ) ^ sq
|
any_number is a constant, so is FNV. Therefore
| Code: |
hash = magin_number ^ sq
|
So that is the hashkey for the square isn't it?
sq=0 gets hashkey = magic_number ^ 0
sq=1 gets hashkey = magic_number ^ 1
....
So unless you make magic_number of FNV different for each square this will clearly be equivalent to hashing with the sq. And if you make any_number different for each square then you will have to store it in a table which is what I said.
