Given two binary strings, return their sum (also a binary string). Have you met this question in a real interview? Yes Example a = 11 b = 1 Return 100 LeetCode上的原题,请参见我之前的博客Add Binary. class Solution { public: /** * @param a a number * @param b a num…

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…

Given two binary strings, return their sum (also a binary string). The input strings are both non-empty and contains only characters 1 or 0. Example 1: Input: a = "11", b = "1" Output: "100" Example 2: Input: a = "1010&q…

C++ class Solution { public: /** * @param a a number * @param b a number * @return the result */ string addBinary(string& a, string& b) { // Write your code here ") { return b; } ") { return a; } string result; ; int ai, bj, sum; char va…

Given two non-negative numbers num1 and num2 represented as string, return the sum of num1 and num2. Note: The length of both num1 and num2 is < 5100. Both num1 and num2 contains only digits 0-9. Both num1 and num2 does not contain any leading zero.…

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…

一.题目描写叙述 Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 二.解题技巧 这道题考察两个二进制数相加,考虑到输入的是两组string,同一时候注意在运算时从左到右各自是从低位到高位,因此须要考虑对输入进行翻转处理,中间二进制树相加部分没有过多的设计障碍.主要是计算进位:…

Given two non-negative numbers num1 and num2 represented as string, return the sum of num1 and num2. Note: The length of both num1 and num2 is < 5100. Both num1 and num2 contains only digits 0-9. Both num1 and num2 does not contain any leading zero.…

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…
