Second order Rubik's Cube

Rubik's Cube can be used for its 6 free rotation of the face. Let's operate a 2 - order cube (1 ) for the sake of convenience, we have set up a coordinate system for it.

The initial state of each polygon is as follows:

X-axis positive: Green

X- axis reverse: Blue

y Axial direction: Red

y axis reverse: orange

Z Axial direction: white

Z axis reverse: yellow

Suppose we stipulate that the Rubik's Cube can only be 3 type of operation. Marked as:

x indicates a clockwise rotation on the x - axis.

y indicates a clockwise rotation on the y - axis.

z indicates clockwise rotation on z-axis

the effect after the basic rotation 2,3,4 is shown.

XYZ indicates sequential execution x, Y, Z 3 an operation

Program Input:

Gets a string from the standard input that represents the sequence of operations.

Program output: The one nearest to our little box 3 the color of the face.

The order is: x Face, y Face, Z face.

For example: In the initial state, the output should be:

Green Red and white

In the initial state, if the user enters:

X

The output should be:

Green and white Orange

In the initial state, if the user enters:

Zyx

The output should be:

Red, white and green

"Realization of thought"

Custom functions: Switch. Case (X Y Z), the string swap can be implemented.
