Layer By Layer
The Layer By Layer method involves solving the 3x3 cube layer by layer.
First step is to make a cross on one side of the cube.
After the first cross,
in this case, green, the next step would be to solve the first layer by
putting the corners into their respective positions.
When the first layer is solved, the next step would be to solve
the second layer.
Next step is to solve the top cross just like the bottom cross,
and then permutate the edges of the top cross.
Second Last step is to permutate the corners into their respective positions
starting with one.
Finally, we orientate the permutated corners and solve the cube!
