Code Explanation:
The provided code is designed to manipulate a simplified representation of a Rubik’s Cube using an algorithm to simulate rotating its faces either clockwise or counter-clockwise. Let’s break down the key components of this program to understand how it achieves its objectives:
- Cube Initialization: The cube is represented as a 6×9 numpy array where each row signifies a face of the cube, coded by colors (W-White, R-Red, B-Blue, O-Orange, G-Green, Y-Yellow).
- rotate_face Function: This function rotates a single face of the cube. It employs numpy’s rot90 method, which rotates arrays 90 degrees in the plane specified by axes. By adjusting the
kparameter based on the direction input, we achieve clockwise or counter-clockwise rotation. - rotate_cube Function: This function encapsulates the logic for rotating an entire layer of the cube around a specified face. The function first rotates the specified face itself. Then depending on the direction of rotation, it appropriately shifts the rows of adjacent faces to simulate a layer rotation in 3D space. The manipulation of indices and the use of slicing and reversing (
[::-1]) are critical to simulate the complex movement of cube layers. - Application: Our example demonstrates rotating the white face clockwise. Post-rotation, you observe that adjacent rows on connected faces have been shifted to new positions, simulating a real Rubik’s Cube rotation.
This simplified algorithm captures the essence of the complexity involved in programming solutions for physical puzzles like the Rubik’s Cube. Its modularity and the use of numpy make it easily extendable for implementing more complex operations and solving algorithms.
