Add BinaryGiven two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". SOLUTION: 指针指到两个字符串的末尾,不断往前推进,用carry表示进位.用stringbuilder来记录结果. 使用insert(0, c)函数将加出的结果不断插入到STRINGBUILDER. pub…

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…

原题地址:https://oj.leetcode.com/problems/add-binary/ 题意: Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 解题思路:提供两种实现方式吧. 代码一: class Solution: # @param a, a string # @pa…

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". class Solution { public: string addBinary(string a, string b) { , alen = a.length(),blen = b.length(); string res=&qu…

Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 求数字字符串的二进制和. 同之前的数组代表数字,两个数组相加一样.仅仅只是进位变成了2.可能两个串的长度不一样,故逆转.从左到右加下去.最后再逆转. public static String addBinary(String a…

Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". Show Tags Have you been asked this question in an interview? public class Solution { public String addBinary(Strin…

Given two binary strings, return their sum (also a binary string). For example,a ="11"b ="1"Return"100". 题意:将两个以字符串形式保存的二进制数进行相加. 思路:其实不管是以数组.字符串形式,加或者乘(multiply strings),一般的思路都是从后往前计算,用一个中间变量保存相加或者相乘的结果(加法是一个变量int 或string就行,…

class Solution { public: string addBinary(string a, string b) { if(a==""&&b=="") return ""; if(a=="") return b; if(b=="") return a; ],*pb=&b[]; ,nb=; ; ,m=; while(*pa!='\0'){ pa++; na++; } pa--…

1 题目 Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 接口 String addBinary(String a, String b) 2 思路 处理二进制求和和进位.从低位开始,一直相加并且维护进位.和Add Two Numbers的区别是这个题目低位在后面,所以要从strin…

顺便把之前做过的一个简单难度的题也贴上来吧 67. Add Binary Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 这种问题 其实大多数人都做烂了 但是在实际应用中这个问题应用很广泛 有用二进制数基本就要处理加减乘除 一种最容易理解的方法但是不高效 那就是转为十进制处理后再转…
