A10961. Anton and Polyhedrons

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!

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.

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

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.
