good luck then! (unless you don't want to do my kata, of course)

ah, great minds think alike

I have no idea, every time I change the example test cases in editor and press "publish", the changes aren't made in the trainer itself. I do have the code for the correct sample test code, written below though. If you, or someone else would help change the sample tests to this, that would be really appreciated.

from solution import solve
import codewars_test as test
from preloaded import *

@test.describe("sample scrambles:")
def tests():
    def do_test(i, scramble):
        @test.it(f"fixed scramble #{i}: {scramble}")
        def _():
            cube = apply_moves(create_copy(SOLVED_CUBE), scramble)
            orig_cube, save_cube = create_copy(cube), create_copy(cube)
            solution = solve(cube).strip()
            apply_moves(orig_cube, solution)
            if is_solved(orig_cube):
                test.pass_()
            else:
                print(f'failed solve.\n\nscramble: {scramble}\n{cube_net(save_cube)}\n\nyour solution: {solution}\n\nresulting state:\n{cube_net(orig_cube)}')
                test.fail('')

    scrambles = [
        "L F2 R' B U' D2 U2 F B' D B2 L B' L' F'",
        "D2 F2 R' F' B' R' U' D2 F' D2 F L2 D2 U' L",
        "R2 F B2 R F U' R2 F R D B2 U2 D2 F R",
        "B' U2 D R2 F D' L D U2 F2 U2 B F2 L' D",
        "F2 R' L F2 R U F2 R B' F D2 L2 F' D' F'"
    ]
    
    for i, scramble in enumerate(scrambles, 1):
        do_test(i, scramble)

sorry, the example test code is wrong and I can't edit them, but the actual test cases do; please press 'attempt' instead of 'test' to test your solution.

thank you,

(reiterated in description)

you make a good point, dfhwze. changed to 4kyu.

agreed, call it "Rubik's Cube simulator" maybe?

ah, maybe I should change it to 4kyu. However the 3x3 solver it estimated at 3kyu only, and the my 2x2 one is much easier imo. Rank inflation is a thing to consider too... Oh well, maybe I should get more completions on my kata first, then let the community decide.

oh my bad, give me a second to fix it

done.

man, another banger problem dude. absolutely loved it, it was incredibly rewarding to finally solve this.

damn, it looks like we had the same idea but you executed it way cleaner, nice job!

glad you enjoyed it, and thanks for doing my kata man! Your solution looks really clean btw, and yeah, at least for me, this kata (and the series in general) wasn't as easy as I thought it was. (also partially because I cannot understand regular expressions for the life of me).

hey, dfhwze, thank you so much for approving my kata! I have just changed the description, does it look better now?

yup, it is the size of the grid, and i think maybe it's just a little more readable that way.

oh damn, that is a much cleaner version of my solution
