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…

encode_json $json_text = encode_json $perl_scalar Converts the given Perl data structure to a UTF-8 encoded, binary string. This function call is functionally identical to: $json_text = JSON->new->utf8->encode($perl_scalar) 转换给定的perl数据结构到一个UTF-8编…

Given a binary string S (a string consisting only of '0' and '1's) and a positive integer N, return true if and only if for every integer X from 1 to N, the binary representation of X is a substring of S. Example 1: Input: S = "0110", N = 3 Outp…

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…

D. Binary String Minimizing You are given a binary string of length n (i. e. a string consisting of n characters '0' and '1'). In one move you can swap two adjacent characters of the string. What is the lexicographically minimum possible string you c…

D1. Kirk and a Binary String (easy version) 01串找最长不降子序列 给定字符串s,要求生成一个等长字符串t,使得任意l到r位置的最长不降子序列长度一致 从后往前暴力枚举,枚举每个一替换成0后是否改变了l到r位置的最长不降子序列长度 01串的最长不降子序列,可以通过线性dp求解 dp i表示以i结尾的最长不降子序列长度 dp[0]=dp[0]+s[i]=='0'; dp[1]=max(dp[0],dp[1])+s[i]=='1'; #include<bi…

CF1400-C. Binary String Reconstruction 题意: 对于一个二进制字符串\(s\),以及一个给定的\(x\),你可以通过一下操作来得到字符串\(w\): 对于字符串\(s\)的第\(i\)位, 1. 如果\(i-x\)有意义并且\(s[i-x]==1\)那么\(w[i]=1\) ; 2.如果\(i+x\)有意义并且\(s[i+x]==1\),那么\(w[i]=1\); 如果上面两条都不符合,那么\(w[i]=0\). 现在题目给出你字符串\(w\)和\(x\),…
