Ural1517 所谓后缀数组, 实际上准确的说,应该是排序后缀数组. 一个长度为N的字符串,显然有N个后缀,将他们放入一个数组中并按字典序排序就是后缀数组的任务. 这个数组有很好的性质,使得我们运行一些算法时 可以大幅度的优化. 本题就是后缀数组的一个主要应用, 快速求得后缀S(i)和S(j)的最长公共前缀LCP. **由字典序的性质可知 S(i)和S(j)的LCP长度就是 h[sa[i]+1],h[sa[i]+2].... h[sa[j]]中的最小值,证明显然. **而如何计算h数组呢? 有…

后缀数组被称为字符串处理神器,要解决字符串问题,一定要掌握它.(我这里的下标全部都是从1开始) 首先后缀数组要处理出两个数组,一个是sa[],sa[i]表示排名第i为的后缀的起始位置是什么,rank[i]表示第i个字符为起始点的后缀,它的排名是什么.可以知道sa[rank[i]] = i; rank[sa[i]] = i; 由于每个后缀各不相同,至起码长度不同,所以每个后缀是不可能相等的. 解除一个值,就能在O(n)时间内得到另外一个. 定义:suffix(i)表示从[i, lenstr]这个后…
