Web每个串都有自己的哈希地址。这取决于需要一个好的哈希函数（BKDRhash），尽量让每个字符串的哈希地址不发生冲突。但有时总存在两个串的哈希地址相同，发生冲突，别急，有解决冲突的办法。 选用的哈希函数： 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取余，以余数作为索引地址，但是这就造成 … See more
