Description

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!

Input

The first line of the input contains a single integer n (1 ≤ n ≤ 200 000) — the number of polyhedrons in Anton's collection.

Each of the following n lines of the input contains a string si — 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.

Output

Output one number — the total number of faces in all the polyhedrons in Anton's collection.

Sample Input

4

Icosahedron

Cube

Tetrahedron

Dodecahedron

Sample Output

42

Hint

题意

给你一堆多面体，然后问你总共多少个面。

题解：

实际上只需要if if if if就好了嘛

代码

#include<bits/stdc++.h>

using namespace std;

int n,ans=0;

string s;

int main(){

    cin>>n;

    for(int i=0;i<n;i++){

        cin>>s;

        if(s=="Tetrahedron")ans+=4;

        if(s=="Cube")ans+=6;

        if(s=="Octahedron")ans+=8;

        if(s=="Dodecahedron")ans+=12;

        if(s=="Icosahedron")ans+=20;

    }

    cout<<ans<<endl;

}
