                                                    Musical Theme 人生第一道后缀数组的题,采用大众化思想姿势极其猥琐. 题意:给你n个数,问其中是否存在一个子序列,这个子序列加上或者减去一个数与另一个子序列一样.要求两个子序列不能有重叠的部分.求这个子序列最长的长度. 思路:有点像KMP,先将所有的数之间的差(再加上88)存在一个数组中,然后对这个数组进行构造后缀数组.我们知道height[]数组的含义是:排名为i的这个后缀与排名…

POJ1743 题目意思是求不重叠的最长相同变化的子串,输出该长度 比如1 2 3 4 5 6 7 8 9 10,最长长度为5,因为子串1 2 3 4 5 和 6 7 8 9 10变化都一样的 思路:既然要求变化一样,那么可以让原数组前后相减,然后利用后缀数组height的性质求子串最长公共前缀即可 height性质:1.height[i]表示排名为i和i-1的子串的最长公共前缀 PS:预处理数组时要留意,把n个数删去第一个 当作n-1个数来求重复子串 (间隔至少为1)然后最长重复子串长度+1就…
