hi, http://www.x5.net/faqs/crypto/q95.html
If some function, when supplied with a random input, returns one of k equally-likely values, then by repeatedly evaluating the function for different inputs, we expect to obtain the same output after about 1.2k1/2. For the above birthday paradox, replace k with 365. how is the result obtained? Regards Sarath. __________________________________________________ Do you Yahoo!? Yahoo!
