# Proper (fast) Python implementations of Dan Bernstein's DJB2 32-bit hashing function
# 
# DJB2 has terrible avalanching performance, though.
# For example, it returns the same hash values for these strings: "xy", "yX", "z7". 
# I recommend using Murmur3 hash. Or, at least, FNV-1a or SDBM hashes below.

import functools
djb2 = lambda x: functools.reduce(lambda x,c: 0xFFFFFFFF & (x*33 + c), x, 5381)
sdbm = lambda x: functools.reduce(lambda x,c: 0xFFFFFFFF & (x*65599 + c), x, 0)
fnv1a_32 = lambda x: functools.reduce(lambda x,c: 0xFFFFFFFF & ((x^c)*0x1000193), x, 0x811c9dc5)
