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 $*s*_{*i*}$ — 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.

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.
