ultimate prime

Prime Number and prime number in C Language I learned C language last semester, but I didn't learn it well. In addition, I have been practicing on my computer, and I have never mastered the C language. Recently I have been eager to learn something, so I started from scratch. Prime numbers have always been my demons. Because I always thought it was very simple,

A good hash function needs to distribute the original data evenly into the hash array.The original data is not really random, there may be some regularity,For example, most are even, this time if the hash array capacity is even, it is easy to make the original data hash will not be evenly distributed.For example 2 4 6 8 10 12 This 6 number, if the 6 to get the remainder of 2 4 0 2 4 0 will only get 3 hash values, the conflict will be manyIf you get 2 4 6 1 3 5 for 7 gain, you get 6 hash values,

This BLOG introduction (there is a UVa524 prime ring advanced edition), uva524 Prime Number [B001] Hi, everyone. Today, my blog was opened on the first day. Today I have a blog question. It was originally entitled UVa524 by OJ, A affiliated Middle School of Capital Normal University, the requirements are as follows: [Difficulty B] Explain ]--------------------------------------------------------------------
