[067-Add Binary(二进制加法)] [LeetCode-面试算法经典-Java实现][全部题目文件夹索引] 原题 Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100" 题目大意 给定两个二进制的字符串,返回它们的和,也是二进行制字符串. 解题思路 先将相应的两个二进制字符

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

这些题目是高精度加法和高精度乘法相关的,复习了一下就做了,没想到难住自己的是C++里面string的用法. 原题地址: 415 Add Strings:https://leetcode.com/problems/add-strings/description/ 67 Add Binary: https://leetcode.com/problems/add-binary/description/ 43 Multiply Strings:https://leetcode.com/problems/

1.回合攻击问题 package com.hone.pdd; import java.util.Scanner; /** * 题目:模拟一个游戏场景,两种伤害,一种正常伤害,一种是先蓄力(也算一个回合),在伤害,问:最多需要多少个回合敌人就会打倒? * 思路:-主要区分bufferedAttach和normalAttach之间的大小,注意是两倍之间的大小区别. * @author Xia * */ public class Test1 { public static void main(Stri

Add Binary 本题收获: 对于相加而言,考虑进位以及进位之后的值为多少,全部进位完毕后进位还为1(11 + 11 = 110)需要添加一位.1.string中默认每个元素为char型 2.从int型转化为char型  s[i] - '0' 从char型转化为int型  s[i] + '0' 3.char型和int型相加时按上式会报错   s = (char)(s[i] + '0') +s s = (char)(s[i] + '0') +s 这样的写法 每次新的s(由(char)(s[i]

Add BinaryGiven two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". SOLUTION: 指针指到两个字符串的末尾,不断往前推进,用carry表示进位.用stringbuilder来记录结果. 使用insert(0, c)函数将加出的结果不断插入到STRINGBUILDER. pub

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:

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

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:

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

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

Add Binary https://leetcode.com/problems/add-binary/ Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 算法 1) 假设aLen表示string a的长度,那么它的第aLen - 1个元素表示的最低位:string b同 2)

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: Inp

题目: Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 题解: 二进制加法都是从最低位(从右加到左).所以对两个字符串要从最后一位开始加,如果遇见长度不一的情况,就把短的字符串高位补0. 每轮计算要加上进位,最后跳出循环后要坚持进位是否为1,以便更新结果. 代码如下(from

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

package addBinary67;/* Given two binary strings, return their sum (also a binary string).For example,a = "11"b = "1"Return "100". */public class Solution { public static String addBinary(String a, String b) { //ensure a.lengt

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

这是悦乐书的第157次更新,第159篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第16题(顺位题号是67).给定两个二进制字符串,返回它们的总和(也是二进制字符串).输入字符串都是非空的,只包含字符1或0. 例如: 输入:a ="11",b ="1" 输出:"100" 输入:a ="1010",b ="1011" 输出:"10101" 本次解题使用的开发工

Description Given two binary strings, return their sum (also a binary string). Example a = 11 b = 1 Return 100 解题:二进制相加.我的思路是,先转成StringBuilder对象(reverse方法比较好用),因为相加是从最后开始,所以先用reverse方法倒转过来.和上一题类似,用carry变量表示进位,0为不进位,1为需要进一位.最后的结果再倒过来.具体细节标注在代码中,代码如下:
