In python Anton's favorite 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. 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  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. Examples: input 4 Icosahedron Cube Tetrahedron Dodecahedron output 42 input 3 Dodecahedron Octahedron Octahedron output 28
