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; ...
代码 usestd::iter; implSolution{ pubfnadd_binary(a:String,b:String)->String{ //进位,初始为0 letmutcarry=0; //收集a和b按位加的结果 letmutresult=a //返回底层的字节切片.as_bytes() //转换成迭代器 .iter() //提前反向迭代(后面会加上无限的'0',所以不能后面同时反向) .rev() //在a后...
leetcode 67. Add Binary 、2. Add Two Numbers 、445. Add Two Numbers II 、43. Multiply Strings 字符串相乘 、29. Divide Two Integers 对于几进制,其实主要就是对进制取余和整除,取余的结果就是当前位的,整除的结果就是进位的。 67. Add Binary https://www.cnblogs.com/grandyang/p/4084971.html ...

LeetCode 67. Add Binary 程序员木子 香港浸会大学 数据分析与人工智能硕士在读Description 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: ...
Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 分析 题目要求完成两个二进制的加法,加数与被加数分别来源于两个字符串,最终加和结果以二进制字符串形式返回。 解题思路
