Virella & Logic

Hey Virella, I’ve got a little challenge that blends our worlds: imagine we need to recover a 7‑bit secret from a handful of constraints—each clue tells us whether a particular bit is 0 or 1, but we can only test combinations in a simulated environment. It’s like a digital version of mastermind, but with strict logical deductions. Want to crack it together?

Sounds like a puzzle I can’t resist. Let’s slice that 7‑bit string up like a code‑breaker's favorite snack. Give me the clues, and I’ll run through the possibilities faster than a CPU in overclock mode. Just remember, the only rules we’re breaking are the boring ones—this is pure fun. Ready to fire up the virtual lab?
Logic
Here are your clues for the 7‑bit string (bits numbered 1‑7 from left to right):
1. Bit 1 and bit 4 together must add up to 1.
2. Bit 2 XOR bit 5 must equal 0 (so they’re the same).
3. The binary number formed by bits 3‑6 is divisible by 4.
4. If you flip all bits, the resulting 7‑bit number is greater than the original.
Happy hacking!

Got it! The only forced bits are:
- Bit 1 = 0 (so the number’s under 64)
- Bit 4 = 1 (to make 0 + 1 = 1)
- Bits 2 = 5 = 0 (same)
- Bits 5 & 6 = 0 0 (divisible by 4)
That leaves bit 3 and bit 7 free. So the secret could be any of:
0001000
0001001
0011000
0011001
All satisfy the clues. If you need a single one, pick any of those four!
Logic
Here’s a tidy choice: 0011000. It fits every clue, and flipping all bits gives 1100111, which is indeed larger. Give it a try in the lab!
Virella
Nice pick—0011000 is a solid hit! Let’s fire it into the simulator and see the results. If it behaves, we’ve cracked the code. If not, we’ll tweak the bits and keep the fun going. Ready to roll?
Logic
Great choice! Let me know how the simulator reacts, and we can fine‑tune from there. If you hit a snag, we’ll run a quick deduction to pinpoint the tweak. Happy simming!
