    Fix 1 cube and try to rotate the other cubes in every possible ways. For one cube there will be 24 possible rotations, so there will be 24n - 1 possible combinations.

      Out of topic but do you know someone named Manh Hung Nguyen Phan and Phuoc Dat Nguyen? Are they still alive? I mean are they still coding?

      Back to C, well, I really did not expect brute force o.O (because I could not prove that the final setting will be that of one of the original cubes), but I see you make it AC, so thank you a lot :))

        Hung and Dat are my classmates. They both quit competitive programming over a year ago to focus on their study and research :D

        About C, the final setting may not be one of the original cubes. In each combination of rotations, you will paint the cubes with the colors that appear the most in each face.

It's ridiculous to remove me from the ranking list. My programs were all done by me and my teammate in 5 hour contest time.
