of modern cryptography system. Because of the slow operation speed of the asymmetric algorithm, the one-way hash function plays an important role in the digital signature protocol. The Hash value, also known as a "digital digest", is digitally signed and can be considered to be statistically equivalent to the digital signature of the file itself. And there are other advantages to such an agreement. 3) Auth

you want the algorithm to use.?? If K is high (k=99), the model will take a large number of neighbors into account in making decisions on the unknown data base. This means that the model is quite limited because it takes a lot of information into account when classifying instances. In other words, a large K-value results in a fairly "rigid" model behavior.?? Conversely, if K
