I'm looking for a Rubik's Cube export who can help me with my code for solving the 2 x 2 Rubik cube. I've been solving the 2x2 cube using a four step method: white bottom (R, U, R’, U’), bottom layer (R’, U’, R, L, U, L’, R’, U’, R), yellow top (R, U, R’, U, R, U2, R’), and final placement (R’, F, R’, B’2, R, F’, R, B’2, R2, B’2). My code works for all steps but there is an issue with the final line of code (R’, F, R’, B’2, R, F’, R, B’2, R2, B’2).
