1923 This algorithm (k=33) was first reported by Dan Bernstein many years ago in
1924 'comp.lang.c'. Another version of this algorithm (now favored by Bernstein)
1925 uses XOR: hash(i) = hash(i - 1) * 33 ^ str[i]; the magic of number 33 (why
1926 it works better than many other constants, prime or not) has never been
1927 adequately explained.
1929 If you just want to have a good hash function, and cannot wait, djb2
1930 is one of the best string hash functions i know. It has excellent
1931 distribution and speed on many different sets of keys and table sizes.
1932 You are not likely to do better with one of the "well known" functions
1933 such as PJW, K&R, etc.
