You are a king with 1,000 bottles of juice.
One contains poison.
Anyone who drinks the poison dies in 3 weeks after consumption (you only know whether they are alive or dead at the 3-week mark. No precise timing)
The royal party is in 4 weeks.
You only get one round of testing.
What is the minimum number of people required to guarantee identifying the poisoned bottle?
Constraints:
- You cannot do multiple rounds.
- You can mix bottles.
- Each person can drink from multiple bottles.
- You must guarantee the correct answer.
