# Python Algorithm Rubik's Cube: Algorithm for 3x3 Rubik's Cube

The Rubik's Cube is a popular 3D combination puzzle that has been enjoyed by people around the world since the 1980s. Solving the Rubik's Cube requires a deep understanding of the puzzle's structure, as well as the ability to apply a series of algorithms to manipulate the cube's various components.

In this article, we will explore the algorithm for solving the 3x3 Rubik's Cube, as well as provide a sample implementation for you to try.

## The Algorithm for Solving the 3x3 Rubik's Cube

The algorithm for solving the 3x3 Rubik's Cube involves a series of steps that must be executed in a specific order. The following is a high-level overview of the algorithm:

### Step 1: Solve the Cross

The first step in solving the Rubik's Cube is to solve the cross on one side of the cube. This involves manipulating the cube's edge pieces until they are all aligned correctly. The following algorithm can be used to solve the cross:

#### Algorithm: F R U R' U' F'

### Step 2: Solve the Corners

Once the cross has been solved, the next step is to solve the corners on the same side of the cube. This involves manipulating the cube's corner pieces until they are all in the correct orientation. The following algorithm can be used to solve the corners:

### Algorithm: R U R' U' R' F R2 U' R' U' R U R' F'

### Step 3: Solve the Middle Layer

After the corners have been solved, the next step is to solve the middle layer of the cube. This involves manipulating the cube's middle layer pieces until they are all aligned correctly. The following algorithm can be used to solve the middle layer:

#### Algorithm: U R U' L' U R' U' L

### Step 4: Solve the Top Cross

Once the middle layer has been solved, the next step is to solve the cross on the top of the cube. This involves manipulating the cube's edge pieces until they are all aligned correctly. The following algorithm can be used to solve the top cross:

#### Algorithm: F R U R' U' F'

### Step 5: Solve the Top Corners

After the top cross has been solved, the next step is to solve the corners on the top of the cube. This involves manipulating the cube's corner pieces until they are all in the correct orientation. The following algorithm can be used to solve the top corners:

#### Algorithm: R U R' U' R' F R F'

### Step 6: Orient the Top Corners

The final step in solving the Rubik's Cube is to orient the top corners of the cube. This involves manipulating the cube's corner pieces until they are all in the correct orientation. The following algorithm can be used to orient the top corners:

#### Algorithm: R U' R U R U R U' R' U' R2

## Implementation

Now that you have an understanding of the algorithm for solving the 3x3 Rubik's Cube, it's time to try it out for yourself. The following is a sample implementation in Python:

def solve_cube(): # Step 1: Solve the Cross algorithm = "F R U R' U' F'" execute_algorithm(algorithm) # Step 2: Solve the Corners algorithm = "R U R' U' R' F R2 U' R' U' R U R' F'" execute_algorithm(algorithm) # Step 3: Solve the Middle Layer algorithm = "U R U' L' U R' U' L" execute_algorithm(algorithm) # Step 4: Solve the Top Cross algorithm = "F R U R' U' F'" execute_algorithm(algorithm) # Step 5: Solve the Top Corners algorithm = "R U R' U' R' F R F'" execute_algorithm(algorithm) # Step 6: Orient the Top Corners algorithm = "R U' R U R U R U' R' U' R2" execute_algorithm(algorithm) def execute_algorithm(algorithm): # Code to execute the algorithm on the Rubik's Cube goes here pass

Note: The execute_algorithm() function should contain the code to actually execute the algorithm on the Rubik's Cube. This will depend on how you are interfacing with the cube (e.g. physical cube, virtual cube in a simulator, etc.).

You can call the solve_cube() function to solve a scrambled Rubik's Cube using the algorithm described above. Remember to ensure that the cube is properly scrambled before attempting to solve it.

I hope this implementation helps you understand how the algorithm can be applied to solve a 3x3 Rubik's Cube. Good luck and happy solving!
