Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". Hide Tags Math String class Solution { public: string addBinary(string a, string b) { string longer=a.length()>b.l…

Given a non-negative integer num, repeatedly add all its digits until the result has only one digit. For example: Given num = 38, the process is like: 3 + 8 = 11, 1 + 1 = 2. Since 2 has only one digit, return it. Follow up: Could you do it without an…

Given two binary strings, return their sum (also a binary string). For example,a = "11"b = "1"Return "100". 简单的二进制相加而已,只不过传入的参数是字符串而已.为了方便,先将string  reverse了一下,代码如下: class Solution { public: string addBinary(string a, string…

翻译 给定一个非负整型数字,反复相加其全部的数字直到最后的结果仅仅有一位数. 比如: 给定sum = 38,这个过程就像是:3 + 8 = 11.1 + 1 = 2.由于2仅仅有一位数.所以返回它. 紧接着: 你能够不用循环或递归在O(1)时间内完毕它吗? 原文 Given a non-negative integer num, repeatedly add all its digits until the result has only one digit. For example: Give…

翻译 给定两个二进制字符串,返回它们的和(也是二进制字符串). 比如, a = "11" b = "1" 返回 "100". 原文 Given two binary strings, return their sum (also a binary string). For example, a = "11" b = "1" Return "100". 分析 我一開始写了这个算法,尽管实现…

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…

package main import ( "fmt" ) func main() { // 字符串 str := "ABCDEFGHIJKLMNOPQRSTUVWXYZ" // 直接使用string强转 例如 string(65) = A fmt.Println(fmt.Sprint(string(str[2]),1)) }…

You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. Input: (2 -> 4 -> 3) + (5 -> 6 ->…

题目: 统计一个字符串中数字和字符串的个数,并分别进行排列,要求 1.数字,字符串可以从键盘获取. 2.储存在list 3.统计数字个数,字符串个数 4.把数字和字符串按从小到大的顺序输出 5.不能使用数组. List的用法 List包括List接口以及List接口的所有实现类.因为List接口实现了Collection接口,所以List接口拥有Collection接口提供的所有常用方法,又因为List是列表类型,所以List接口还提供了一些适合于自身的常用方法.[自行百度] List接口提供的…

You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers…
