Zone Movement
Zone Movement puzzles involve people moving between different zones over multiple time slots. Each person moves according to a fixed pattern, and multiple people can occupy the same zone simultaneously. You must track zone occupancy at different times and answer questions about which zone has a specific number of people.

Introduction to Zone Movement
Zone Movement puzzles involve people moving between different zones over multiple time slots. Each person moves according to a fixed pattern, and multiple people can occupy the same zone simultaneously. You must track zone occupancy at different times and answer questions about which zone has a specific number of people.
Prerequisites
How to Solve Zone Movement Problems
Step 1: Identify all persons, zones, and time slots
Step 2: Note each person's movement pattern (e.g., A→B→C, or stay, etc.)
Step 3: Create a table with time slots as columns and persons as rows
Step 4: Fill each person's zone at each time slot based on their movement pattern
Step 5: For each time slot, count how many people are in each zone
Step 6: Answer the specific question (e.g., which zone has exactly 2 people at time T)
Example Problem
Example: Four persons in zones A,B,C,D over 3 time slots. P1: A→B→C, P2: B→B→D, P3: C→D→A, P4: D→D→B. Which zone has exactly 2 people at time 2? Solution: Step 1: Time1: P1=A, P2=B, P3=C, P4=D (each zone 1 person) Step 2: Time2: P1=B, P2=B, P3=D, P4=D → B has 2, D has 2 Step 3: Time3: P1=C, P2=D, P3=A, P4=B → each 1 person Answer: Zones B and D have exactly 2 people at time 2
Pro Tips & Tricks
- Create a table: Persons × Time Slots
- A movement pattern like 'A→B→C' means zone changes each time
- A pattern like 'B→B→D' means person stays in B at time 2
- Each person's movement pattern is fixed and known
- Multiple people can be in the same zone at the same time
- Count occupancy by scanning each time slot column
