Rubik's cube was once known as one of the three largest intellectual toys in the world, but now I dare not say so. What? What are the other two? You can remember; That's the Ninth Ring Road of China, arrest and release Cao!

The Rubik's Cube can be disassembled. That's bullshit！ But ... have you opened it? If not, quickly remove the Rubik's cube piece by piece, gnome male-",is there a feeling of hitting the doomsday monster? Did you unload it? It can be seen that there are eight corner blocks and 12 edge blocks besides the six central blocks with different colors on the skeleton.

There is only one color in the center building block, two colors on the sides and three colors on the corners. Anyway, no two blocks are exactly the same. The central building block on the skeleton can't move, so the relative position of the central building block and the central building block is fixed, so the correct position of the building block on the corner side is also fixed. For example, a red, yellow and blue corner building block, its correct position is on the corner of the corresponding surface of the red, yellow and blue center building block. Our task is to turn the prism block and the corner block to their own positions.
