Given two binary stringsaandb, returntheir sum as a binary string. Example 1: Input:a = "11", b = "1"Output:"100" Example 2: Input:a = "1010", b = "1011"Output:"10101" Constraints: 1 <= a.length, b.length <= 104 aandbconsist only of'0'or'1'characters. Each string does...
Given two binary strings, return their sum (also a binary string). For example, a ="11" b ="1" Return"100". 解题思路1:判断当前字符所表示的数字,产生输出和进位。缺点:程序比较复杂。 代码1: class Solution { public: string addBinary(string a, string b) { char carry='0'; string c; ...

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...
