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). 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(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…
题目: 二进制求和 给定两个二进制字符串,返回他们的和(用二进制表示). 样例 a = 11 b = 1 返回 100 解题: 和求两个链表的和很类似 考虑进位,考虑最后一项的进位 0+0 = 0 不需要进位 0+1 = 1 不需要进位 1+1 =0  进位 1 同时注意 低位进1,高位时1+1的情况,直接加就是3了,这个需要进位1 ,原位的结果也是1的情况 Java程序: public class Solution { /** * @param a a number * @param b a…
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…
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…
[抄题]: 以字符串的形式给出两个非负整数 num1 和 num2,返回 num1和 num2 的和. 比如一个50位+一个100位. 给定 num1 = "123",num2 = "45" 返回 "168" [暴力解法]: 时间分析: 空间分析: [思维问题]: [一句话思路]: [输入量]:空: 正常情况:特大:特小:程序里处理到的特殊情况:异常情况(不合法不合理的输入): [画图]: [一刷]: sum求和或者循环退出的条件都是i j &g…
