1 Do not go overboard on the line, I let a friend get married next of kin, he and other male relatives in the home, the results to the woman would not let us into the house, and then have to come up with jewelry worth 5000 then pro-when the entry fee, I We were a few guys who rely on it Cou Cou it has only over 2000, to the groom to call, he said, people first take out, and then to either the card directly into the account the woman's relatives, the results do not agree with people distracted, non- to ready-made jewelry, instrument allows to engage well done my friend, and directly with the phone is not connected to us yelling, and all floats all back to the hotel, this time for all when he invited all friends and family to eat dinner meal.

Answer 2

本人不会C#，算法相通，用c语言演示一下：
#include<stdio.h>
void main(void)
{
int zhengshu=0;
int result = 0;
scanf("%d\n",&zhengshu);
while(zhengshu!= 1)
{
if(zhengshu / 2 == 0)
{
zhengshu = zhengshu /2;
}else
{
zhengshu = zhengshu *3+1;
}
result ++;
}
printf("一共经过了%d次运算\n",result);
}
我没有测试，也没有编译，应该对的，你试试。。。本回答被提问者采纳

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string input;
int intNum;
do
{
Console.WriteLine("Press 'Q' to exit. \n");
Console.Write("请输入一个整数: ");
input = Console.ReadLine();
if (int.TryParse(input, out intNum))
{
Console.WriteLine("共计算了{0}次!", Calc(intNum));
}
} while (input.ToUpper() != "Q");
}

static int Calc(int intNum)
{
int iCalcCount = 0;
int iResult = 0;
if (intNum == 1) return 0;
if (intNum % 2 == 0) //偶数
{
iCalcCount++;
iResult = intNum / 2;
Console.WriteLine("算式: {0} / 2 = {1}", intNum, iResult);
iCalcCount += Calc(iResult);
}
else
{
iCalcCount++;
iResult = intNum * 3 + 1;
Console.WriteLine("算式: {0} * 3 + 1 = {1}", intNum, iResult);
iCalcCount += Calc(iResult);
}
return iCalcCount;
}
}
}

Answer 4

楼上的 应该是%2 代表余数 /2=0 那就是小于2了
