思路：水题，翻译成代码就好。

代码如下：

#include <stdio.h>#include <stdlib.h>#include <string.h>/* run this program using the console pauser or add your own getch, system("pause") or input loop */int main(int argc, char *argv[]) {int n;int a[200];int sum;int i;while(scanf("%d",&n) && n!=0){memset(a,0,sizeof(a));sum=0;a[0]=0;for(i=1;i<=n;i++){scanf("%d",&a[i]);if(a[i]-a[i-1]>0){sum=sum+(a[i]-a[i-1])*6+5;}else{sum=sum+(a[i-1]-a[i])*4+5;}}printf("%d\n",sum);}return 0;}
