【前言】

    很久没有纯粹的写写小代码，偶然想起要回炉再来，就去HDU随便选了个最基础的题，也不记得曾经AC过；最后吃惊的发现，思路完全不一样了，代码风格啥的也有不小的变化。希望是成长了一点点吧。后面定期去做做题、保持青春的活力！

1、青年回炉

2、从代码中发现成长的轨迹

2.1 曾经的代码

#include
     
      using namespace std;int main(void){
         int a[100],i,j,n,flag,down;    long total;    while(cin>>n&&n)    {
             a[0]=total=flag=down=0;        for(i=1;i<=n;i++)        {
                 cin>>a[i];            if(!down)            {
                     if(a[i]>a[i-1])continue;                total+=6*(a[i-1]-a[flag]);                flag=i-1;down=1;            }            else            {
                     if(a[i]
      
       a[n-1])total+=(a[n]-a[flag])*6;        else    total+=(a[flag]-a[n])*4;        total+=5*n;        cout<
       
        <
