The last layer of the Rubik's Cube has been put together, but only one side is intact on all sides. The middle of the other three sides is different. I forgot the formula. Can anyone tell me?

After the first two layers are assembled, first draw a cross on the third layer, using R'U'F'UFR. Do this formula at most three times and the cross will be drawn on the top layer, and then the fish will appear. Shape, that is, a cross plus a corner block. At this time, there are two formulas, (1): R'U'RU'R'U2'R (2): RUR'URU2R', use these two formulas Just restore the top surface, and then you have to memorize another formula to restore the entire Rubik's Cube. (3) LF'LB2L'FLB2L2. For beginners, you only need to memorize these four formulas. If you want to memorize it again, just memorize it again. There are two three-cycle formulas, one is forward and the other is inverse! After the first two layers are assembled, first draw a cross on the third layer and use R'U'F'UFR.
