761. Special Binary String 题意: 一个符合以下两个要求的二进制串: \(1.串中包含的1和0的个数是相等的.\) \(2.二进制串的所有前缀中1的个数不少于0的个数\) 被称为特殊二进制串 要求我们任意交换两个相邻的特殊二进制串(可以交换任意次)使得最终得到的序列的字典序最大,并且满足是特殊二进制串. 思路: 我们可以将1看作是上升,0是下降,那么可以这样 然后我们可以找最外层符合要求的子串也就是最底部从水平线开始又降到水平线的段,可以发现找这样的串只要统计一个cnt…

Special binary strings are binary strings with the following two properties: The number of 0's is equal to the number of 1's. Every prefix of the binary string has at least as many 1's as 0's. Given a special string S, a move consists of choosing two…

E. Vasya and Binary String 链接 分析: 对于长度为x的一段序列,我们可以dp出消除的过程的最优方案,背包即可. 然后区间dp,可以先合并完所有的点,即没相同的一段区间合并为一个点.设f[i][j][k]表示消完区间[i,j]和这段区间后面k个元素最大值,其中k个元素的颜色与点j的颜色相同. 转移:可以首先将j和后面k个元素消除,然后消除[i,j-1].也可以枚举一个和j颜色相同的点m,然后分别先消除[m+1,r-1],剩下的区间就和后面k个连在一起了,再求出这段区间的…

题目链接:Mahmoud and Ehab and the binary string 题意: 一道交互题,首先给出一个字符串的长度l.现在让你进行提问(最多15次),每次提问提出一个字符串,会返回这个字符串与目标串之间不同的字符的个数.要在15次的提问内,找到目标串中任意一个1和0的位置. 题解: 因为是15次提问,其实可以想到二分,但是分别对0和1进行二分差不多要二十多次,所以可以对01或10进行二分,查找某一个01或10串的位置. #include<bits/stdc++.h> usin…
