standard inputoutput

standard outputAnton'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 *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

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

Output

28

Note

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.
