Anton and Polyhedrons
题意翻译
题目描述
Anton最喜欢的几何图形是正多面体。
有五种正多面体：
四面体：有4个4个三角形的面。
立方体：有6个6正方形的面。
八面体：有8个8个三角形的面。
十二面体：有12个12个五边形的面。
二十面体:有20个20个三角形的面。
形状如图：
编写程序，帮Anton求出他的n个多面体的总面数s。
输入输出格式
输入：
第一行为一个整数N（1<n<＝200000）
第2~n+1行包含一个字符串s[i]（Anton集合中的第i个多面体的名称）
输入方式如下（不带引号）：
“Tetrahedron”表示四面体；
“Cube”表示立方体；
“Octahedron”表示八面体；
“Dodecahedron”表示十二面体；
“Icosahedron”表示二十面体。
输出格式：
输出一个整数s。
说明：
在第一个样例输入中，Anton有一个二十面体、一个立方体、一个四面体和一个十二面体。二十面体有20个面，立方体有6个面，四面体有4个面，十二面体有12个面。所以，它们一共有20 + 6 + 4 + 12＝42个面。

题目描述
Anton's favourite geometric figures are regular polyhedrons. Note that there are five kinds of regular polyhedrons:
- Tetrahedron. Tetrahedron has $ 4 $ triangular faces.
- Cube. Cube has $ 6 $ square faces.
- Octahedron. Octahedron has $ 8 $ triangular faces.
- Dodecahedron. Dodecahedron has $ 12 $ pentagonal faces.
- Icosahedron. Icosahedron has $ 20 $ triangular faces.
All five kinds of polyhedrons are shown on the picture below:
Anton has a collection of $ n $ polyhedrons. One day he decided to know, how many faces his polyhedrons have in total. Help Anton and find this number!
输入输出格式
输入格式
The first line of the input contains a single integer $ n $ $ (1<=n<=200000) $ — the number of polyhedrons in Anton's collection.
Each of the following $ n $ lines of the input contains a string $ s_{i} $ — the name of the $ i $ -th polyhedron in Anton's collection. The string can look like this:
- "Tetrahedron" (without quotes), if the $ i $ -th polyhedron in Anton's collection is a tetrahedron.
- "Cube" (without quotes), if the $ i $ -th polyhedron in Anton's collection is a cube.
- "Octahedron" (without quotes), if the $ i $ -th polyhedron in Anton's collection is an octahedron.
- "Dodecahedron" (without quotes), if the $ i $ -th polyhedron in Anton's collection is a dodecahedron.
- "Icosahedron" (without quotes), if the $ i $ -th polyhedron in Anton's collection is an icosahedron.
输出格式
Output one number — the total number of faces in all the polyhedrons in Anton's collection.

说明
In the first sample Anton has one icosahedron, one cube, one tetrahedron and one dodecahedron. Icosahedron has $ 20 $ faces, cube has $ 6 $ faces, tetrahedron has $ 4 $ faces and dodecahedron has $ 12 $ faces. In total, they have $ 20+6+4+12=42 $ faces.
