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…
67. Add Binary Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 两个字符串存储二进制数,进行二进制加法,返回相加之后的结果. 代码如下: class Solution { public: string addBinary(string a, string b) { ;…
https://leetcode.com/problems/add-binary/ 题目: Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 思路: 数组模拟加法操做,注意首位进一的情况. class Solution { public: string addBinary(strin…
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…
Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 这个题目只要注意各种情况你就成功了一大半,特别要注意的是对进位赋值后可能产生的变化,以及最后一位进位为1时, 我们要把这个1插进来.同时注意字符串的低位是我们数值的高位 class Solution { public: string…
题目描述: Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 解题思路: 使用StringBuilder,且使用进位. 代码如下: public class Solution { public String addBinary(String a, String b) { String…
