WebAPI documentation for the Rust `bkdr_hash` fn in crate `hash_algorithms`. 由一个字符串(比如:ad)得到其哈希值,为了减少碰撞,应该使该字符串中每个字符都参与哈希值计算,使其符合雪崩效应,也就是说即使改变字符串中的一个字节,也会对最终的哈希值造成较大的影响。我们直接想到的办法就是让字符串中的每个字符相加,得到其和SUM,让SUM作为哈希值,如SUM(ad)= a+d;可 … See more 由上面三步的推导可知,这个系数应当选择大于1的奇数,这样可以很好的降低碰撞的几率,那么我们就可以根据上面推导的公式,用代码实现: bkdrhash的初步代码实现如下: 其实我们可以对 … See more 注意:即使最终求得的bkdrhash值几乎不会冲突碰撞,但他们都是很大的值,不可能直接映射到哈希数组地址上,所以一般都是直接对哈希数组大小 … See more WebHash tables deal with collisions in one of two ways. Option 1: By having each bucket contain a linked list of elements that are hashed to that bucket. This is why a bad hash function can make lookups in hash tables very slow.
