leetCode 67.Add Binary (二进制加法) 解题思路和方法

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…

[leetcode]67. Add Binary 二进制加法

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…

Leetcode 67 Add Binary 大数加法+字符串处理

题意:两个二进制数相加,大数加法的变形 大数加法流程: 1.倒置两个大数,这一步能使所有大数对齐 2.逐位相加,同时进位 3.倒置两个大数的和作为输出 class Solution { public: string addBinary(string a, string b) { if(a.size() < b.size()){ string t = a; a = b; b = t; } //该步使的能大数加小数,使其能加 reverse(a.begin(),a.end()); reverse(b…

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…

(String) leetcode 67. Add Binary

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

[Leetcode] add binary 二进制加法

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,…

leetcode 67. Add Binary （高精度加法）

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 简单的二进制高精度加法. class Solution { public: string addBinary(string a, string b) { string ans=""; ,i=a.length()-,…

LeetCode 67. Add Binary （二进制相加）

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 题目标签:Math 题目给了我们两个string a 和 b,让我们把这两个二进制 相加. 首先把两个string 的长度得到,然后从右向左 取 两个string 的 digit. 增设一个 carry = 0: 每一轮把 digit…

LeetCode 67 Add Binary（二进制相加）（*）

翻译 给定两个二进制字符串,返回它们的和(也是二进制字符串). 比如, a = "11" b = "1" 返回 "100". 原文 Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 分析 我一開始写了这个算法,尽管实现…
