leetcode add_binary 采坑记 尽管add_binary在leetcode中是一个简单难度,但是踩了不少坑,记录一下 描述: 给两个字符串形式的二进制数,要求求和并输出字符串形式的结果,其中a和b均不为空字符串 样例: a=“1010”,b="1011",输出“10101”. 过程: 刚看到题目的时候觉得很简单,只要每一位按位相加就好了,很...

代码: class Solution { public: string addBinary(string a, string b) { int temp,len_a,len_b; len_a = a.size(); len_b = b.size(); string::iterator itr_a = a.end() - 1; string::iterator itr_b = b.end() - 1; string str_a =a; string str_b =b; if(len_a<len_b)...
https://leetcode.com/problems/add-binary/ 知道二进制加法原理即可,这里只需要知道进位是除数,余数是结果就行。最后不要忽略reg里面的值 class Solution(object): def addBinary(self, a, b): """ :type a: str :type b: str :rtype: str
来自专栏 · 刻意练习之LeetCode #67.Add Binary 先尽量正确理解题目:实现二进制的加法。 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. Examples: Input: a = "11", b = "1"; Output: "100" Input...
