给定两个二进制字符串,返回他们的和(用二进制表示).案例:a = "11"b = "1"返回 "100" .详见:https://leetcode.com/problems/add-binary/description/ Java实现: class Solution { public String addBinary(String a, String b) { String s=""; int c=0; int i=a.len…
Leetcode 67:Add Binary(二进制求和) (python.java) 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. 给定两个二进制字符串,返回他们的和(用二进制表示). 输入为非空字符串且只包含数字 1 和 0. Example 1: Input…
Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 思路:二进制加法,比較简单.代码例如以下: public class Solution { public String addBinary(String a, String b) { int len = Math.max(a.l…
Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 解题思路: JAVA实现如下: static public String addBinary(String a, String b) { if (a.length() < b.length()) { String temp…
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&qu…

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,…
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…
