前言

1008 Elevator 一道比较简单的模拟题目， 注意翻译好题目意思.

题目概述

1008 Elevator

分数 20

The highest building in our city has only one elevator. A request list is made up with N positive numbers. The numbers denote at which floors the elevator will stop, in specified order. It costs 6 seconds to move the elevator up one floor, and 4 seconds to move down one floor. The elevator will stay for 5 seconds at each stop.

For a given request list, you are to compute the total time spent to fulfill the requests on the list. The elevator is on the 0th floor at the beginning and does not have to return to the ground floor when the requests are fulfilled.

Input Specification:

Each input file contains one test case. Each case contains a positive integer N, followed by N positive numbers. All the numbers in the input are less than 100.

Output Specification:

For each test case, print the total time on a single line.

Sample Input:

3 2 3 1

Sample Output:

41

分析思路

1. 题目很简单，就是每次上一层楼要花6s， 下一层楼要花4s， 然后每次把客人送到一个地方，要在那个地方停留5s，注意只是在有客人要下电梯的楼层等待5s，中途路过的楼层是不等的。

学习算法和数据结构真的是个很累的过程，不会做只能求助于题解。 因为写代码这个东西基本上是千人千面。同时网络上搜到的题解很多要么用到的是自己还没学到的知识，看不懂;要么内核过于简陋，只能糊弄当前题目，不具有普适性。
如果你是一个喜欢做洛谷，ACwing和PTA的题目的同学，欢迎关注我的博客，我主要在这三个平台上做题，认为有价值和有难度的题目我会写题解发布出来。
