题意:判断长度为n的串中的每个长度为k的子串是否0和1相等,字符串中的问号既可以是1也可以是0。解题思路:例如n=10 ,k=4 对于 s[0~3] 和 s[1~4] 我们可以发现1~3的部分是相同的,那么不难发现0和4相同,同理可得s[2]和s[5]也是相同的因此若该串合理就一定是k循环节子串,最后我们只需要判断前k个字母是否可以构造出一半1和一半0 ,如果1或者0的个数已经大于一半了一定构造不出来,否则一定可以构造出来。代码:#include<iostream>#include.

【题目链接】 点击打开链接 【算法】 这是一道经典的最值查询(RMQ)问题。 我们首先想到线段树。但有没有更快的方法呢?对于这类问题,我们可以用ST表(稀疏表)算法求解。 稀疏表算法。其实也是一种动态规划的算法。是先做一遍预处理,然后O(1)求出答案。 设计状态 : f[i][j] 表示从第i个数开
