Your Goal
Complete the whole cube by achieving the following sub-goals.
Your Sub-Goal
Check the third layer's four corner sides for matching color pairs.
Then, position the matching pair on the left and execute the algorithm.
(If the cube doesn't have a pair of corner, the same algorithm will create a pair.)
Your Sub-Goal
Put the solved side at the back. Then, repeat the following algorithm until solved.
(If the cube doesn't have a solved side, the same algorithm will create a solved side.)
