KMP - LeetCode #459 Repeated Substring Pattern

复习一下KMP算法 KMP的主要思想是利用字符串自身的前缀后缀的对称性,来构建next数组,从而实现用接近O(N)的时间复杂度完成字符串的匹配 对于一个字符串str,next[j] = k 表示满足str[0...k-1] = str[j-k...j-1]的最大的k,即对于子串str[0...j-1],前k个字母等于后k个字母 现在求解str的next数组: 初始化:next[0] = -1 那么在知道了next[j]的情况下,如何递推地求出next[j+1]呢?分两种情况(令k=next[j]…
