Temporal Ordering Linear
Temporal Ordering Linear problems involve arranging items (tasks, people, events) in a linear sequence from first to last with constraints like 'X is immediately before Y', 'X is before Y', 'exactly n items between X and Y', and positional exclusions.

Introduction to Temporal Ordering Linear
Temporal Ordering Linear problems involve arranging items (tasks, people, events) in a linear sequence from first to last with constraints like 'X is immediately before Y', 'X is before Y', 'exactly n items between X and Y', and positional exclusions.
Prerequisites
How to Solve Temporal Ordering Linear Problems
Step 1: Number positions 1 to N (where N = number of items)
Step 2: Apply direct placement constraints (e.g., 'X is not first or last')
Step 3: Apply consecutive constraints: |pos(X) - pos(Y)| = 1
Step 4: Apply before constraints: pos(X) < pos(Y)
Step 5: Apply gap constraints: |pos(X) - pos(Y)| = gap + 1
Step 6: Use elimination to determine positions
Step 7: Answer which item is at a specific position
Example Problem
Example: Arrange A,B,C,D,E,F (6 items). Constraints: A before B. C and D consecutive. E not first or last. Two items between F and A. Which is third? Solution: Step 1: Positions 1-6 Step 2: E not in 1 or 6 Step 3: C and D consecutive → (1,2),(2,3),(3,4),(4,5),(5,6) Step 4: Two items between F and A → |pos(F)-pos(A)| = 3 Step 5: A before B → pos(A) < pos(B) Step 6: Systematic deduction yields specific arrangement Answer: [Item at position 3]
Pro Tips & Tricks
- Number positions 1 to N for easy reference
- Consecutive: positions differ by exactly 1
- Before: position of first < position of second
- Gap of n items: |pos1 - pos2| = n + 1
- Draw a line with position slots
- Use elimination table for positions
