Cube

// Cube
//Ivcho is a big computer genius. One day he was bored from all the girls that wanted to be with him and instead decided to wright //a computer game. Because he always likes to do things the hard way he decided to make a console game, but not any console game – //a 3D one! Just for the fun of it. But because he isn’t very good with graphics he needs your help with the basic building blocks //witch he can feed to his magic algorithm that produces HD 3D-reality in the console.
//Your task is to wright a program that supplies him with cubes (basic building blocks). He will give you a number N and you should //print a cube with width = height = depth = N as shown in the examples. Mark the sides with “:” (colon).
//In addition you will have to fill in some of the sides of the cube:
//•   The top should be filled in with “/” (slash)
//•   The side should be filled in with “X” (capital letter X)
