第七周 Leetcode 466. Count The Repetitions 倍增DP (HARD)

Leetcode 466 直接给出DP方程 dp[i][k]=dp[i][k-1]+dp[(i+dp[i][k-1])%len1][k-1]; dp[i][k]表示从字符串s1的第k位开始匹配2^k个s2串需要的长度 最后通过一个循环 累积最多可以匹配多少个s2串 除以n2下取整就是答案 用倍增加速后 总的复杂度nlogn 而本题的n非常小 轻松AC 体会到倍增的魅力了吧. const int maxn=100+1,INF=1e+9; long long int dp[maxn][30]; cl

LeetCode 466 - Count The Repetitions - Hard ( Python)

Define S = [s,n] as the string S which consists of n connected strings s. For example, ["abc", 3] ="abcabcabc". On the other hand, we define that string s1 can be obtained from string s2 if we can remove some characters from s2 such th

LeetCode --- 字符串系列 --- 特殊等价字符串组

特殊等价字符串组 注释:这道题目题意太过难理解,理解题意花了几小时... 下面将对题目进行括号注释.... 题目 你将得到一个字符串数组 A.比如 (["a2cd","ac2d","2acd", "c2ad"]) 如果经过任意次数的移动,S == T,那么两个字符串 S 和 T 是特殊等价的. (比如上面给出的字符串数组,若其中两个数组元素字符串,自身的字符发生任意次数的移动, 移动次数不用相等,最后这两个字符串可以相等,那么

【算法】LeetCode算法题-Count And Say

这是悦乐书的第153次更新,第155篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第12题(顺位题号是38).count-and-say序列是整数序列,前五个术语如下: 1 11 21 1211 111221 1被读作"一个一"或者11.第二项的值是第一项的读法. 11被读作"两个一"或者21.第三项的值是第二项的读法. 21被读作"一个二,两个一"或者1211.第四项的值是第三项的读法. 给定整数n,其中1≤n≤3
