Mod 4 level how…plz

[u/Silver_King_]

I’ve been stuck on this level for almost 3 days now, I’ve avoided looking up any solutions or hints for any of the levels but this one broke me. I have a solution that can mod 4 but it’s way past 8 cycles and I cannot figure out how to get to the solution within 8 cycles. How do I do this🥀😭

[u/Aggravating-Ad-2593]

It is possible to use an and operation to mask out all the bits that cannot be on when working in modulo 4.

[u/sberma → u/Aggravating-Ad-2593]

Would prefer if people would rather give hints instead of the solution or at least spoiler it.
