【ACM】HDU1008 Elevator 新手题前后不同的代码版本

【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<iostream>
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[i-1])continue;total+=4*(a[flag]-a[i-1]);flag=i-1;down=0;}}if(a[n]>a[n-1])total+=(a[n]-a[flag])*6;else    total+=(a[flag]-a[n])*4;total+=5*n;cout<<total<<endl;}return 0; }

2.2 现在的风格

#include <stdio.h>
 int main(){
      int count=0;int cur_floor=0;int last_floor=0;int total_time=0;int i=0;scanf("%d", &count);while (count != 0){
      total_time = 0;last_floor = 0;for (i=0; i<count; i++){
      scanf("%d", &cur_floor);if (cur_floor > last_floor){
      total_time += 6*(cur_floor-last_floor);}else{
      total_time += 4*(last_floor-cur_floor);}total_time += 5;last_floor = cur_floor;}printf("%d\n", total_time);scanf("%d", &count);}return 0; }
