Can you beat The Matrix ?!
dev0 on 1:18 PM 06/06/2022: At the moment I can not beat the Matrix. Reversing it is fairly simple but the valid_key algorithm is a bit troubling. I see that the shift and multiply essentially divide by 2 and zero out the 2 least significant bits. When summed I do not see mathematically how the total that is compared can be computed with the algorithm. I know it has been solved because it is currently a lvl 3.6. Is there a way to mathematically calculate it with using brute force?
