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 ->…
2.5 You have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1's digit is at the head of the list. Write a function that adds the two numbers and returns the sum…
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…

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…
今天在页面上用到了js进行小数相加119.01+0.01,结果大家都知道应该是:119.02的,然而结果是119..0200000…. ,莫名其妙的,还以为是我写的程序有问题,后来查了下才知道这是javascript浮点运算的一个bug. 解决方案 1.这是因为Javascript的数字类型是以64位的IEEE 754格式存储的. 2.解决方法把相加的结果做下处理 function toDecimal(x) { var val = Number(x) if(!isNaN(parseFloat(v…
设计思想:定义双精度变量 i 和 s=0 ,定义另一个变量 n 作为计数,方便之后求平均值.程序里将数据输入 i 中,通过 s 来将各个数据求和,最后除 n 得平均值. 程序流程图: 源程序代码: package jiafa; import java.util.*; public class jia { public static void main(String[] args){ System.out.println("请输入相加的数(最后请输入任意字母来结束输入并进行运算):");…
