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 Format: 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 Format: 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.
