Go up one level in this thread


Maybe I'm missing something here, but if you furthermore agree to use a hash
table of size 2^i, i <= 32, you can replace all mods, divs and muls by a 32 bit
'and'. The performance hit of the slightly smaller table (less than factor 2)
should be outweighed by the faster access.

just my 2 bits
