unreachable values for CityHash32 and CityHash64

[rom...@gmail.com]

Hi,

I need at least 2 uint32 and uint64 values that can not be produced by CityHashXX functions.

The reason for that is that I would like to use them for dense_hash_set data structure that requires 2 special values for marking its state.

Do you know of such values?

Thanks!

Update: if applying CityHash32 on 4 byte value described by integer 1005356300 (stored as little endian)

we get 0. So 0 is reachable.

there are no reserved values
