题目链接 题目描述： ZZT 得到了一个字符串 S 以及一个整数 K。 WZH 在 1995 年提出了“优雅 K 串”的定义：这个字符串每一种字符的个数都是 K 的倍数。 现在 ZZT 想要对字符串进行 Q 次询问，第 i 次询问给出一个区间 [Li, Ri]，他想计算 [Li, Ri] 中有多少个子串是“优雅 K 串”。 由于 ZZT 忙于工作，所以他把这个问题交给了你，请你帮忙解决。 输入描述: 第一行输入一个正整数 K。 第二行输入一个字符串 S。 第三行输入一个正整数 Q，表示有 Q 次询问。 接下

Crazy Binary String 题意：给你一个长度为n的01字符串，问该字符串中01个数相等的最长子串和子序列分别是多少。 分析： 首先，大家要知道什么是子序列，什么是子串，子序列是不一定是连续的，它可以是原串中任意元素按照相对位置组成的序列，但是子串就不是了，子串一定是连续的，不可分割的按照绝对位置组成的序列。 知道这个概念之后，大家可以明显的看出，子序列这个答案好求，就是暴力一下，...
