Greedy Interval Scheduling

The Greedy Interval Scheduling technique is applied when tackling problems characterized by specific invariants in the problem state or constraints:

• Core Strategy: Sort intervals by end time and greedily keep/skip each one to maximize non-overlapping selections.
• 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.
