【Leetcode】Add Binary 题目: 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) { ...
class Solution: def addBinary(self, a: str, b: str) -> str: sumInt = int(a, 2) + int(b, 2) sumBin = bin(sumInt) #string starts with '0b' return sumBin[2:] # equally, but more precise # return bin( int(a, 2) + int(b, ) )[2:] # return '{:b}'.format(int(a...
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;
leetcode -- Add Binary -- 简单要了解 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...
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
Leetcode - Add Binary Paste_Image.png My code: public class Solution { public String addBinary(String a, String b) { if (a == null || a.length() == 0 || b == null || b.length() == 0) return null; int len = Math.max(a.length(), b.length()) + 1;...
Add Binary https://leetcode.com/problems/add-binary/description/ 主要是全加器的公式: s = abc c = (a^b)&c | (a&b) 其他的没什么 就去一下零处理 以及颠倒一下列表 classSolution(object):defaddBinary(self,a,b):""" :type a: str...
1.将两个字符串按数组相加得到新数组。 2.将新数组转换成结果。 代码如下: class Solution { public: string addBinary(string a, string b) { int sizeA = a.size(); int sizeB = b.size(); int carry = 0; vectorresult; string resultStr; ...
