题目如下: 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 =…

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…

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…

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…

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 二进制数想加,并且保存在string中,要注意的是如何将string和int之间互相转换,并且每位相加时,会有进位的可能,会影响之后相加的结果.而且两个输入string的长度也可能会不同.这时我们需要新建一个string,它的长度是两…
