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…
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…
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:…
题目 Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 分析 一个简单的字符串相加,该题目要注意两点: 字符位的求和计算,必须转换为整型,即: 如下利用'0'字符作为中间转换,才得到正确结果. int temp = (a[i]-'0') + (b[i]-'0'); char c…
Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 简单的二进制相加而已,只不过传入的参数是字符串而已.为了方便,先将string reverse了一下,代码如下: class Solution { public: string addBinary(string a, string…
67. Add Binary Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". public class Solution { public String addBinary(String a, String b) { String res =""; int l1…
1.题目 67. Add Binary——easy 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:…
