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.

题目大意

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。

提示

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.
