[leetcode] 67. Add Binary (easy)

原题链接 思路: 用一个数保存进制,从后往前不断pop出两个数字和进制数相加,放入返回值中. var addBinary = function(a, b) { var arrA = a.split(''); var arrB = b.split(''); var len = Math.max(a.length, b.length), c = 0, result = ''; while(len-- > 0 || c > 0) { let va = arrA.pop(); let vb = arr…

LeetCode 67. Add Binary【个位补0，不必对齐】【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: Input: a = "1010&q…

[leetcode]67. Add Binary 二进制加法

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. Example 1: Input: a = "11", b = "1" Output: "100" Example 2: Input: a = "1010&q…

LeetCode 67. Add Binary （二进制相加）

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…

[LeetCode] 67. Add Binary 二进制数相加

LeetCode 67. Add Binary

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 这个题目只要注意各种情况你就成功了一大半,特别要注意的是对进位赋值后可能产生的变化,以及最后一位进位为1时, 我们要把这个1插进来.同时注意字符串的低位是我们数值的高位 class Solution { public: string…

Java [Leetcode 67]Add Binary

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…
