Algorithmic Intuition & Recognition
The Greedy Single-Pass Decision technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:
- Core Strategy: Make a locally optimal choice while scanning once left to right, where the specific decision rule is simple enough not to warrant its own named pattern.
- When to use: Look for opportunities where repeated re-computation can be replaced by maintaining monotonic properties, state windows, or relational pointers.
- Interview Signal: Demonstrating this pattern shows mastery of Greedy foundations, reducing worst-case algorithmic complexity.
